Many therapists employ a communication model for couples work that assumes that most couples' problems derive from dysfunctional communication. The assumption seems to be that teaching better communication should resolve their difficulties. Unfortunately, most well-controlled studies show that only about one-third of the couples going through marital therapy are reporting significant post-treatment benefits. Those are not impressive statistics and they do not give much support for a simplistic communication therapy model. A couple's communication usually breaks down because of more complex emotional dynamics. Those dynamics can involve historical shame issues, personality deficits, knowledge deficits, and boundary interactions. These issues can be quite complex but are still understandable. At Allied Psychological Services, teaching effective communication is only one small piece of a more comprehensive strategy. Even more emphasis is placed upon teaching a couple principles of effective emotional regulation. This may involve learning how to influence one's own emotional state before projecting rage or behaving in a way that is toxic to the relationship. Old shame issues are clarified so that they do not unconsciously disrupt the relationship. Principles of "tact" are taught so that both partners experience less threat to their psychological boundaries while negotiating their needs. Couples are also taught about how "ego states" are often critical to getting their needs met and how to anticipate and schedule getting together so that both parties are receptive to each other. Sometimes, other forms of therapy will be a necessary first step in couple's work. For example, sometimes group therapy or individual therapy is necessary to change a person's internal emotional responses before the couple's external interactions can constructively become the main focus.
While teaching is often employed in good couple's work, an emphasis is also placed on homework between sessions. The therapist often assigns homework in the form of communication or behavioral exercises. For example, a couple may be assigned homework to re-enact a recent argument but to do it in a newly agreed upon way. An individual may also be given homework to practice self-talk or guided imagery to deal with irrational beliefs or old feelings of shame that are intruding into the relationship. There are many other forms of homework that are too numerous to list here. The main point is that Allied Psychological Services therapists place an emphasis on practice and implementation in addition to insight.

This type of individual therapy is the most simple and entails what people refer to as "counseling." It usually involves a lot of teaching and prescribed exercises at home. A significant part of counseling is to teach clients about human nature so that they have realistic expectations of themselves. Clients are often taught how to more effectively relax, how to fashion realistic goals from their own needs and desires, how to journal to promote emotional growth, how to compartmentalize grief, how to confront and replace automatic irrational beliefs, how to use autosuggestion for shifting emotions, how to manage situational cues to influence their emotional states, and many other self-management strategies. Our style of counseling has a reputation for being very direct and friendly.
Currently, individual psychotherapy for adults is being offered by Dr. Bryce Kaye. Check his staff profile to read about his style of psychotherapy.
"EMDR" is an acronym for "Eye Movement Desensitization and Reprocessing". This is a technique of therapy invented by a superb clinician Dr. Francine Shapiro in 1989. Dr. Shapiro discovered that the brain seems to metabolize and reduce the emotional pain from traumatic memory if a patient can simultaneously recall the memories while attending to bilateral sensory stimulation. The term "bilateral" here refers to a sensory stimulus that alternately arouses the right and left hemispheres of the brain. In the form of EMDR practiced by Dr. Kaye, a moving dot of light on a screen is used to provide the sensory stimulation while various components of the troubling memory are requested by the therapist. Brain scan research in the last 10 years has suggested that the amygdala and hypocampus areas of the brain are very involved in preventing and later resolving traumatic memory. EMDR therapy is thought to possibly stimulate this mechanism. Whatever the mechanism, there are more controlled effectiveness studies on EMDR than for any other form of treatment for Post Traumatic Stress Disorder. Many of the Oklahoma bombing survivors were treated using this technique. If interested, more background information on EMDR comparison studies can be mailed to you.

Who's behind the mysterious money hunt downtown?

A new San Diego startup is sending people on a wild goose chase of sorts. That company, GoMeta Inc., has crafted an iPhone app-powered adventure that will take the curious on a scavenger hunt through downtown city streets on Saturday. The game will conclude with one person finding at least $500 in cash.
GoMeta isn't giving away money just to be generous. The motive is to get the town buzzing about the startup's just-launched app, Metaverse, a kind of parallel universe that employs augmented reality in the same fashion as Pokemon Go. So just as Pokemon Go players can point their smartphone camera at the world around them to capture so-called pocket monsters, Metaverse users on Saturday afternoon can scan the streets with their phones to track down virtual clues on a quest to find free cash.
"Pokemon Go showed people that it's fun to walk around and discover things in the world," said Dmitry Shapiro, 47, who is CEO and co-founder of GoMeta. "And we're saying, 'Yes!'."
Those who want to play need only download the Metaverse iPhone application and make their way to the downtown area around noon. Then, they just await a ping from the app with instructions on what to do next.

For now, Metaverse is just a one-time scavenger hunt app. While the local company behind it has raised an undisclosed sum of seed funding for a grander vision around augmented reality, it's not ready to reveal the full scope of its machinations. In fact, until now, the startup has sought to keep its identity unknown, orchestrating the scavenger hunt through a Facebook event where nothing is revealed except the cash prize. The promise of free money has resulted in about 4,000 strangers on Facebook expressing interest in attending the event.
Before its official launch, GoMeta plans to orchestrate similar secretive out-and-about adventures in Los Angeles and San Francisco. Then, when Halloween rolls around, the real Metaverse will materialize.
The ambiguity is intentional. Shapiro, who recently spent over four years at Google before returning to San Diego, loves the idea of surprising people. Because that, he insists, is what gets people's serotonin pumping. And that also seems to be the overarching goal of Metaverse — to stimulate the senses in a real-slash-virtual game that kind of, sort of resembles life.

For said purpose, Shapiro, a repeat entrepreneur, has teamed with two first-timers, Sean Thielen and Jonathan Miller. The latter are both 23-year-old graduates of Chapman University, and they built the Metaverse app before recruiting Shapiro to the fold. Now the three men comprise an atypical family, cohabitating at Shapiro's expansive compound in Spring Valley, with Thielen and Miller living in the large garage.
The three co-founders are just starting to build a bigger team and are recruiting from big Bay Area tech companies, including Google. Right now, they all work together out of their neighbors' "room," though it's not just any room. The neighbors run a 13,000 square-foot bed-and-breakfast, called Vineyard Hacienda, and Shapiro likens their rented space to a castle. They've nicknamed this office, "The Lair."
The GoMeta team also keeps more traditional office space at EvoNexus downtown.
Despite being publicly cagey about the true intention of the Metaverse app, Shapiro is more than happy to boast that his master plan involves building a San Diego-based startup large enough to defy our sleepy-tech town reputation and perhaps even redefine that reputation altogether.
Free money is quick way to get attention. The true test, though? Once the money runs out, will anyone care?

This is the second in series of my trip to Radisson Blu Resort Temple Bay in Mahabalipuram. I challenged a North Indian friend, who said there's nothing to do near Chennai in the summers. I told him I could transform his life through experiences on a Saturday and Sunday. Lets dive in to the series! If you have landed directly here, Read Part-1 and Part-0 for context!
Soon after we finished cycling, we went over and had our breakfast at the Water's edge cafe. It was a good spread, but we were late and needed to finish it before they close. One thing we observed was that due to the searing heat, seats near the glass area were less air-conditioned than the ones inoculated from the heat. The summer is usually un-relenting for a body that is not used to such heat, and we had to find a cozy corner where the effect of the sun, does not eat into the air-conditioning. I had a couple of fruit juices along with Idli/Dosa and bread for my breakfast.
I had told Tej about the ATV ride at the beach, and we wanted to go and try it out. Both of us were excited about speeding in the sand, and turning at angle, throwing mud in the air. Some primal things as a kid, stay in our memory and pop up while outdoors like our wish lists.
These ATV machines need a strong grip to get used to. That may take about 5 minutes as the hands bonds with the controls. My ATV seemed to be inclined to curve right as opposed to go straight.
Tej was a little stronger than me, and he loved the ride on the sand. He went quite fast on the sand, and won the competition to ride better! But hey, never forget to have fun!
Secondly, the real fear is when you drive fast, what if you lose control and get into the sea. If the ATV gets into the sea, it will be a problem, as such devices/cars are not supposed to be in salt water, while they can otherwise be driven on wet sand.
Do watch and check how our ATV Ride went!
Wow not only your Temple bay Part 1, but even the part 2 seems to be very interesting. I have never tried ATV ride yet. I am sure it must have been very fun. I liked the tip where you mentioned that it takes at least 5 min for your hand to bond control with the vehicle. Have to keep that in mind.
Shreya-Thanks! It takes time to bond depending on the strength your arms have for adrenalin :-). My friend found it easy i guess!
Hell yeah! That looks like a cool trip. We used to ride ATV next to our summer house in Russia. And yeah, that is really cool.
WOW riding the quad bikes on the sand looks like an awesome experience. We ride them in the bush a lot here in Australia but haven't had the opportunity to let loose on the sand yet!
Thanks Daniel for your kind words! So you drove the ATV where in Vietnam? Do you have a link to the post?
All terrain vehicles can certainly be a lot of fun! Although you do really have to be careful when driving quickly on dry sand. I'm glad you had fun!
Sound do interesting. I would love to spend some time here.
This is a wonderful experience. I loved the video, I haven't ever been on a All Terrain Vehicle but I really like to to imagine the thrill ride that one would get on it.
Thanks Anshul. Its fun when you ride on a surface that you traditionally don't fancy driving. I just was in awe of the power this vehicle has, but it takes some time getting used to this.
Your series is quite interesting. Looked like you both had a lot of fun. I had wanted to ride an ATV in Mahabalipuram, but we were not allowed as it was raining that time. Maybe, next time!
ATV's are monsters and quite tough to handle. The first time we rode one, it took some time to master them. We did manage to climb a short hill and ride through some rough terrain. But never tried it on the sand. Must have been quite an experience that.
Whoa! This is super cool. I'm hoping to visit Mahabalipuram in a couple months. I have to introduce the fascinating place to my little gal. Guess I'll make time for myself too and check out the ATV machines!
Yes Bhushavalli. Its a nice place to soak yourself in an environment with relaxed vibes. The ATV is fun to drive around!

FIELD: physics.
SUBSTANCE: invention relates to the field of data processing. System and method for adaptive event recognition, in which a selected sensor of a head-mounted display device is used at a first polling frequency corresponding to a higher potential delay. Initial information associated with a user is received. When the initial information is consistent with a pre-event, the selected sensor is used at a second polling frequency greater than the first polling frequency and the corresponding lower potential delay. Subsequent information associated with the user is received. When the subsequent information is consistent with the selected target event, the estimated execution time is determined, when the selected target event occurs, and a feedback signal is issued to the user, associated with the selected target event, through the head-mounted display device.
EFFECT: technical result is to reduce the delay in processing the gesture input.
[0001] In user interface systems, minimizing the delay experienced by the user between user input and the system response to input creates a more natural and pleasant user experience. For example, in augmented reality systems, reducing such a delay provides a higher quality and more realistic perception of augmented reality. In some augmented reality systems, one or more sensors may receive user input that initiates a system response. To track such user input, the system may periodically poll sensors for input. The sampling delay corresponding to the polling rate can be a significant source of delay perceived by the user.
[0002] Additionally, with respect to portable and other self-powered devices, it is also possible to consider issues of reducing power consumption and, accordingly, increasing battery life. Although the constant use of high sensor sampling rates can reduce sample delay, it also leads to an undesirable increase in power consumption and shortened battery life. On the other hand, although the use of low sample rates can reduce power consumption and increase battery life, such low sample rates also increase latency.
[0003] Various embodiments are disclosed herein that relate to systems and methods for recognizing a selected target event. For example, one disclosed embodiment provides a method that includes, in a display device comprising a plurality of sensors, using the selected sensor at a first polling frequency corresponding to a higher potential delay. The initial user-related information from the selected sensor is received. The method includes determining whether the initial user-related information is consistent with one of a plurality of pre-events, each of the pre-events corresponding to one or more different pre-event patterns, and each of the patterns leads to a separate possible target event.
[0004] When the initial user-related information is consistent with one of a plurality of pre-events, the method includes using the selected sensor at a second polling frequency that is higher than the first polling frequency and which corresponds to a lower potential delay that is less than more high potential delay. Subsequent user information is received from the selected sensor. When subsequent information associated with the user is consistent with the selected target event from various possible target events, a feedback signal associated with the selected target event is provided to the user by the display device.
[0005] This summary of the invention is intended to present in a simplified form the basic principles, which are further described in the following detailed description. This summary of the invention is not intended to identify key features or essential features of the claimed invention, nor is it to be used to limit the scope of the claimed invention. In addition, the claimed invention is not limited to implementations that eliminate some or all of the disadvantages indicated in any part of this invention.
[0006] FIG. 1 is a schematic view of an adaptive event recognition system according to an embodiment of the present invention.
[0007] FIG. 2 shows an example of a head-mounted display device according to an embodiment of the present invention.
[0008] FIG. 3 is a schematic illustration of pre-events in the form of hand movements leading to a selected target event.
[0009] FIG. 4 is a schematic illustration of recorded upstream events shown in FIG. 3 and a polling frequency of a sensor controlled according to an embodiment of the present invention.
[0010] FIG. 5 is a schematic illustration of a plurality of pre-event patterns leading to various possible target events.
[0011] FIG. 6A and 6B are a flowchart of a method for recognizing a selected target event according to an embodiment of the present invention.
[0012] FIG. 7 is a simplified schematic illustration of an embodiment of a computing device.
[0013] FIG. 1 is a schematic view of one embodiment of an adaptive event recognition system 10. Adaptive event recognition system 10 includes an adaptive event recognition program 14 that can be stored in the high-capacity data storage 18 of computing device 22. Adaptive event recognition program 14 can be loaded into memory 26 and executed by processor 30 of computing device 22 to implement one or more methods and processes described in more detail below. Computing device 22 may further include a power source 32, such as a battery, for supplying power to components of the computing device.
[0014] The adaptive event recognition system 10 includes a mixed reality display program 34 that can generate a virtual environment 38 for display by a display device, such as a head-mounted display (HMD) device 42, to create a mixed reality environment 44. The mixed reality environment includes a virtual environment 38 displayed in the physical environment 48. As described in more detail below, user related information 52 can be received from the physical environment 48 via the HMD device 42.
[0015] Computing device 22 may take the form of a desktop computing device, a mobile computing device, such as a smartphone, laptop computer, laptop or tablet computer, network computer, home entertainment computer, interactive TV, gaming system, or other suitable computing device type. Additional details regarding the components and computing aspects of computing device 22 are described in more detail below with reference to FIG. 7.
[0016] Computing device 22 may be operatively connected to the HMD device 42 using a wired connection, or may use a wireless connection via WiFi, Bluetooth, or any other suitable wireless communication protocol. For example, computing device 22 may connect to a network 16 with the ability to transmit data. Network 16 may take the form of a local area network (LAN), wide area network (WAN), wired network, wireless network, personal area network, or a combination thereof, and may include the Internet.
[0017] Computing device 22 may also communicate with one or more other computing devices through network 16. Additionally, the example shown in FIG. 1 shows a computing device 22 as a separate component of an HMD device 42. Obviously, in other examples, computing device 22 may be integrated into HMD device 42.
[0018] Now, with reference also to FIG. 2, one example of an HMD 200 is provided in the form of a pair of wearable glasses with a transparent display 54. In other examples, the HMD 200 can take other suitable forms in which a transparent, translucent or opaque display is supported in front of the eye or eyes of the observer. It is also apparent that the HMD device 42 shown in FIG. 1 may take the form of an HMD 200 device, as described in more detail below, or any other suitable HMD device. Additionally, many other types and configurations of display devices having various form factors can also be used within the scope of the present invention. Such display devices may include handheld smartphones, tablet computers, and other suitable display devices.
[0019] With reference to FIG. 1 and 2, the HMD device 42 includes a display system 56 and a transparent display 54 that allows delivering images, for example, holographic objects, to the eyes of the user 46. The transparent display 54 may be configured to visually complement the appearance of the physical environment 48 to a user 46 observing the physical environment through the transparent display. For example, the appearance of the physical environment 48 may be supplemented by graphic content (for example, one or more pixels, each of which has a corresponding color and brightness), which is presented through a transparent display 54 to create a mixed reality environment.
[0020] The transparent display 54 may also be configured to allow a user to observe a physical object of the real world in the physical environment 48 through one or more partially transparent pixels that display a representation of the virtual object. As shown in FIG. 2, in one example, the transparent display 54 may include image forming elements located in the lenses 204 (e.g., for example, a transparent organic light emitting diode display (OLED)). As another example, the transparent display 54 may include a light modulator at the edge of the lens 204. In this example, the lens 204 can serve as a light guide to deliver light from the light modulator to the user's eyes. Such a light guide may enable the user to perceive a 3D holographic image located in the physical environment 48 observed by the user, while also allowing the user to observe physical objects in the physical environment, thereby creating a mixed reality environment 44.
[0021] The HMD device 42 may also include various sensors and associated systems. For example, the HMD device 42 may include an eye movement tracking system 60 that uses at least one inwardly facing sensor 208. The sensor 208 facing inward may be an image sensor that is configured to receive image data in the form of eye tracking data from the user's eyes. If the user has agreed to receive and use this information, the eye movement tracking system 60 may use this information to track the position and / or movement of the user's eyes.
[0022] In one example, the eye movement tracking system 60 includes a gaze direction detection subsystem configured to detect a gaze direction of each user's eye. The gaze direction detection subsystem may be configured to determine the gaze directions of each of the user's eyes in any suitable manner. For example, the gaze direction detection subsystem may comprise one or more light sources, for example, infrared light sources, configured to cause a flash of light to reflect from the cornea of each user's eye. One or more image sensors may be configured to capture an image of a user's eyes. In some examples, the eye movement tracking system 60 can also be used as a user input device to provide user related information 52, which allows the user to interact with the HMD device 42 through user eye movements.
[0023] The HMD device 42 may also include sensor systems that receive physical environment data, such as user related information 52, from the physical environment 48. For example, the HMD device 42 may include an optical sensor system 62 that uses at least one sensor 212 facing outward, for example, an optical sensor for capturing image data from the physical environment 48. The sensor 212 facing outward can detect movements in its field of view, such as gesture inputs or other movements performed by the user 46 or a person or physical object in the field of view. The outward facing sensor 212 can also capture two-dimensional image information and depth information from the physical environment 48 and the physical objects in the environment. For example, an outward facing sensor 212 may include a scene depth sensing camera, a visible light camera, an infrared light camera, and / or a position tracking camera.
[0024] The HMD device 42 may include depth sensing through one or more cameras with scene depth sensing. In one example, each camera with a scene depth perception may include left and right cameras of a stereoscopic vision system. Time-spaced images from one or more of these cameras with scene depth perception can be combined with each other and / or with images from another optical sensor, for example, a visible spectrum camera, and can be combined to produce depth-diversity video.
[0025] In other examples, a structured light camera with scene depth perception can be configured to project structured infrared lighting and form an image using lighting reflected from the scene onto which the lighting is projected. A map of the depths of the scene can be built based on the gaps between adjacent features in different parts of the depicted scene. In other examples, a scene depth sensing camera may take the form of a time-of-flight camera with scene depth sensing, configured to project pulsed infrared lighting onto a scene and register lighting reflected from the scene. Obviously, any other suitable camera with a perception of scene depth can be used within the scope of the present invention.
[0026] The outward facing sensor 212 may capture images of the physical environment 48 in which the user 46 is located. In one example, the mixed reality display program 34 may include a 3D modeling system that uses this input to generate a virtual environment 38 that models the physical environment 48 surrounding user 46.
[0027] The HMD device 42 may also include a position sensor system 66 that uses one or more motion sensors 220 to capture position data, and thus provide motion detection, position tracking and / or orientation detection of the HMD device. For example, position sensor system 66 may be used to determine the direction, speed, and / or acceleration of a user's head. The position sensor system 66 can also be used to determine the orientation of the head pose for the user's head. In one example, the position sensor system 66 may comprise an inertial measurement unit configured as a position sensor system with six axes or six degrees of freedom. In this example, a position sensor system may, for example, include three accelerometers and three gyroscopes for indicating or measuring the location change of the 42 HMD device in three-dimensional space along three orthogonal axes (e.g. x, y, z), and the orientation of the HMD device relative to three orthogonal axes (e.g. roll, pitch, yaw).
[0028] The position sensor system 66 may also support other suitable positioning methods, such as GPS or other global navigation systems. Additionally, although specific examples of position sensor systems have been described, it will be appreciated that other suitable position sensor systems may be used. In some examples, motion sensors 220 can also be used as user input devices to provide user related information 52, allowing the user to interact with the HMD device 42 through gestures of the neck and head, or even the body.
[0029] The HMD device 42 may also include a biometric sensor system 70 that uses one or more biometric sensors 232 to capture user biometric data. For example, biometric sensor system 70 may be used to measure or determine user biometric data, including, for example, heart rate, pupillary response, hemoglobin saturation, skin conduction, respiration, sweating, and brain activity.
[0030] The HMD device 42 may also include a microphone system 72 that includes one or more microphones 224 that capture audio data. In other examples, audio may be presented to the user through one or more speakers 228 on the HMD device 42. The first HMD device 42 may also include a battery 74 or other suitable portable power source that provides power to various components of the HMD device.
[0031] The HMD device 42 may also include a processor 236 having a logical subsystem and a storage subsystem, as discussed in more detail below with respect to FIG. 7, which communicate with various sensors and systems of the HMD device. In one example, the storage subsystem may include instructions executable by the logic subsystem for receiving signal inputs from sensors and forwarding such inputs to computing device 22 (in raw or processed form), and for presenting images to a user through a transparent display 54.
[0032] Obviously, the HMD device 42 and the corresponding sensors and other components described above and shown in FIG. 1 and 2 are provided by way of example. These examples are not intended to be limiting in any way, since any other suitable sensors, components, and / or a combination of sensors and components may be used. Therefore, it should be understood that the HMD device 42 may include additional and / or alternative sensors, cameras, microphones, input devices, output devices, etc. without deviating from the scope of this invention. Additionally, the physical configuration of the HMD device 42 and its various sensors and subcomponents can take a variety of forms without departing from the scope of this invention.
[0033] Also, and as discussed in more detail below, it is apparent that various sensor systems and corresponding components can operate at different polling rates or frequencies to track user related information 52 provided by the user 46. As described in more detail below, polling frequencies one or more sensors can be adjusted in response to a determination of whether user related information 52 is consistent with a pre-event.
[0034] Now, with reference to FIG. 3-5, we provide descriptions of use cases and embodiments of the adaptive event recognition system 10. In the following examples, user related information 52 in the form of hand movements and corresponding gestures is received by the optical sensor system 62. Obviously, in other examples, many other forms of user-related information 52 can be received and used by the adaptive event recognition system 10 to control the operation of the sensors, as described in more detail below. Such other forms of user related information 52 include, but are not limited to, other user movement data, eye tracking data, position data, biometric data, and audio data.
[0035] FIG. 3 schematically illustrates a pre-event in the form of hand movements leading to a selected target event containing a target gesture. In the example shown in FIG. 3, one or more optical sensors in the optical sensor system 62 of the HMD device 42 may capture image data of a user's hand 304 performing a hand gesture. In this example, the index finger 308 and thumb 312 make a pinch gesture in which the user starts with the finger and thumb forming an open, generally U-shaped pose 316. From this pose 316, the user closes the gap between the index finger 308 and thumb 312 until the finger and thumb converge, forming a plucked pose 330.
[0036] In one example, and as described in more detail below, upon detecting that the user has completed the pinch gesture by bringing the index finger 308 and thumb 312 into the pinch position 330, the adaptive event recognition system 10 may provide a feedback signal 78 to the user 46 through the device 42 HMD. The feedback signal 78 may comprise, for example, executing a command regarding a program executed by the HMD device 42. For example, the pinch gesture shown in FIG. 3 may be used by a photographic application to capture photographs of the physical environment 48. In this example, the feedback signal 78 may also include indicating to the user that the photograph is captured, for example, by providing shutter sound, a flashing icon, etc., by means of the device 42 HMD.
[0037] In other examples, the feedback signal 78 may comprise any other command used in the context of user input, for example, selecting, copying, or pasting an item displayed to the user through the HMD device 42. In other examples, the team may control the operational aspect of the HMD device 42 or other electronic device. Obviously, the above examples are merely illustrative, and that the feedback signal 78 may comprise any command, action, notification, or other event that is associated with a selected target event, for example, a target gesture, and be provided to the user.
[0038] As mentioned above, in order to provide a realistic and believable user experience, it is desirable to minimize any delay between the user input, for example, the target gesture, and the corresponding feedback signal. However, minimizing the delay may include the continuous use of sensors at high polling frequencies, which is associated with increased power consumption, increased computing load and, consequently, reduced battery life. Advantageously, and as described in more detail below, the adaptive event recognition system 10 can reduce latency while also minimizing power consumption and computational load, thereby prolonging battery life.
[0039] Also with reference to FIG. 4 and 5, in one example, the adaptive event recognition program 14 may be configured to receive user related information 52 containing image data from the optical sensor system 62, showing the user's hand 304 in various poses, including the poses shown in FIG. 3. As shown in FIG. 3 and 4, from the Start 402 state corresponding to the point in time, the adaptive event recognition program 14 can be configured to use the selected sensor from the optical sensor system 62 with the default polling frequency that corresponds to the highest potential delay. The default polling frequency may be, for example, 0.5 Hz, 1.0 Hz, 5.0 Hz, or any other suitable frequency. Such a default polling rate may also correspond to the lowest power state of the selected sensor.
[0040] The selected sensor operating at the default polling frequency can receive user-related information 52, for example, user hand image 304 data, and transmit such information to the adaptive event recognition program 14. Then, the adaptive event recognition program 14 may determine whether such information is consistent with one of a plurality of pre-events (PEs). Now, with reference to the example shown in FIG. 5, from the Start 402 state, the adaptive event recognition program 14 may determine whether the user related information 52 is consistent with the PE 506, PE 510, PE 514, or PE 518. As shown in FIG. 5, each of the pre-events PE 506, PE 510, PE 514, and PE 518 corresponds to one or more different pre-event patterns, and each of the patterns results in a separate possible target event (TE). For example, PE 510 corresponds to 3 different patterns indicated at 522, 526 and 530, which lead to 3 different target events TE 534, TE 538 and TE 542, respectively.
[0041] It is obvious that for each subsequent detected pre-event, the number of possible target events is reduced. Additionally, the likelihood that the user is in the process of executing a particular possible target event increases. Accordingly, and as described in more detail below, when each pre-event is detected and the current position in this pattern approaches the target event, the polling frequency of the selected sensor can be increased to reduce the delay. Additionally, until a subsequent upstream event has been detected, the polling frequency of the selected sensor may remain at a relatively lower frequency in order to thereby save energy and increase battery life.
[0042] In one example and also with reference to FIG. 3, the adaptive event recognition program 14 may receive image data of a user's hand 304 forming a generally U-shaped pose 316. The adaptive event recognition program 14 may determine that, in general, the U-shaped pose 316 is consistent with PE 510 in FIG. . 5. PE 510 is an element of patterns 522, 526, and 530.
[0043] Accordingly, the adaptive event recognition program 14 may transition to the state Detect1 406 in which the polling frequency of the selected sensor is increased to operate at the polling frequency Faster F1 which is higher than the default polling frequency of the Start 402. For example, when the default polling frequency is 1.0 Hz, the polling frequency of Faster F1 can be 10 Hz. The increased Faster F1 polling frequency of Detect1 406 state also corresponds to the increased power consumption of the selected sensor, indicated as Higher P1, compared to the power consumption of Start 402. The Faster F1 polling frequency of Detect1 406 also corresponds to a reduced potential delay, indicated as Reduced L1, which is less than Highest potential Start 402 state delay.
[0044] For the purposes of this invention, the potential delay of a sensor operating at a given polling frequency is defined as the maximum potential time period between the occurrence of an event, such as a pre-event or a target event, and the detection of the occurrence of an event by the sensor. For example, when the probe polling frequency is 1 Hz, the potential delay associated with this polling frequency may be approximately 0.99 s. In other words, approximately 0.99 s will be the maximum potential elapsed time between the occurrence of an event, for example, a pre-event or a target event, and the detection of the occurrence of the event by the sensor. Accordingly, increasing the polling frequency of the sensor, respectively, reduces the potential delay of this sensor. It is also obvious that in some examples, the actual delay between the occurrence of the event and the detection of the occurrence of the event by the sensor will be less than the potential delay in the operation of this sensor.
[0045] From the state Detect1 406, the adaptive event recognition program 14 may receive image data of a user's hand 304 forming a modified U-shaped pose 320, in which the index finger 308 and thumb 312 are closer to each other than in the previous pose 316. Program Adaptive Event Recognition 14 may determine that the modified U-shaped pose 320 is consistent with PE 550 in FIG. 5. PE 550 is an element of patterns 522 and 526. Thus, the possible target events are reduced to TE 534 and TE 538.
[0046] Accordingly, the adaptive event recognition program 14 may transition to a state of Detect2 410 in which the polling frequency of the selected sensor is increased to operate at the polling frequency Faster F2, which is higher than the polling frequency Faster F1 of the state Detect1 406. For example, when the polling frequency Faster F1 is 10 Hz, the polling frequency of Faster F2 can be 60 Hz. The increased Faster F2 polling rate of Detect2 410 status also corresponds to the increased power consumption of the selected sensor, indicated as Higher P2, compared to the higher power consumption of Dether Detector1 406 Higher P1. The Faster F2 polling rate of Detect2 410 also corresponds to an additionally reduced potential delay, indicated as Reduced L2, which less than the potential delay of the Reduced L1 state of Detect1 406.
[0047] From the state of Detect2 410, the adaptive event recognition program 14 may receive image data of a user's hand 304 forming a close to pinch pose 32 in which the index finger 308 and thumb 312 are separated by a smaller distance, for example, approximately 2 mm, compared with a modified U-shaped pose 320. The adaptive event recognition program 14 may determine that a close-pinch pose 324 is consistent with PE 554 in FIG. 5. PE 554 is an element of template 522. Thus, the possible target events are reduced to a single target event, TE 534.
[0048] Accordingly, the adaptive event recognition program 14 may transition to the Detect3 414 state in which the polling frequency of the selected sensor is increased to operate at the Faster F3 polling frequency, which is higher than the Faster F2 polling frequency of the Detect2 410 state. For example, when the Faster F2 polling frequency is 60 Hz, the polling frequency of Faster F3 can be 120 Hz. The increased Faster F3 polling rate for Detect3 414 state also corresponds to the increased power consumption of the selected sensor, indicated as Higher P3, compared to the higher power consumption of Detect2 410 status Higher P2. The Faster F3 polling frequency for Detect3 414 also corresponds to an additionally reduced potential delay indicated as Reduced L3, which less than the potential delay of the Reduced L2 Detect2 410 state.
[0049] From the Detect3 state 414, the adaptive event recognition program 14 may receive image data of a user's hand 304 forming a plucked pose 330, in which the index finger 308 and thumb 312 are in contact, as indicated by the occurrence state 418 of the target event 534. Adaptive recognition program 14 events can determine that the pinch position 330 is consistent with the selected target event TE 534 in FIG. 5. Then, the adaptive event recognition program 14 may provide a feedback signal associated with the selected target event TE 534 to the user via the HMD device 42.
[0050] With reference to FIG. 4 and 5, in some examples, the adaptive event recognition program 14 may be configured to reduce the sampling rate of the selected sensor when user related information 52 corresponding to the pre-event is not received within a predetermined time frame. For example, when the Detect1 state is triggered, the adaptive event recognition program 14 may start a timer. If user-related information 52 corresponding to one of the following possible pre-events PE 550 and PE 552 is not received within a predetermined time frame, then adaptive event recognition program 14 may provide a delay condition and return to Start 402 corresponding to a lower default polling rate and lowest power consumption.
[0051] Similar expiration conditions can be used for Detect2 and / or Detect3 states. Advantageously, in this way, power consumption can be reduced when the probability of receiving the next possible upstream event falls below a predetermined threshold that corresponds to a predetermined time frame. In one example, predefined time frames for an overdue condition may be 3 s for the Detect1 state, 2 s for the Detect2 state, and 1.0 s for the Detect3 state. Obviously, any suitable predetermined time frames and predetermined probability thresholds can be used.
[0052] Advantageously, by maintaining the polling frequencies of the sensor at lower frequencies until a pre-event is detected, the adaptive event recognition system 10 minimizes the power consumption of the sensor as well as the consumption of the sensor signal band. For example, waiting for the sensor to operate at the highest Faster F3 polling rate until PE 554 is detected, you can avoid the Higher P3 power state until the probability of the selected target event exceeding a predetermined threshold.
[0053] Additionally, the adaptive event recognition system 10 sequentially increases the sampling rate of the selected sensor as additional upstream events are detected. Thus, as shown in FIG. 3, the corresponding potential delays between the occurrence and the detection of a pre-event are successively reduced. In addition, using the sensor at the highest Faster F3 polling rate after detecting PE 554, the adaptive event recognition system 10 also minimizes the potential delay between the occurrence of the selected TE 534 target event and the event detection.
[0054] In another example, prior to detecting the selected target event 534, the adaptive event recognition program 14 may preselect at least a portion of the feedback signal 78 associated with one or more target events. For example, in the state of Detect2 410, which corresponds to PE 550 in FIG. 5, there remain two possible patterns 522 and 526 and two possible target events TE 534 and TE 538, respectively. In this example, in the Detect2 410 state, the adaptive event recognition program 14 can preselect a portion of the feedback signal 78 associated with both TE 534 and TE 538. In one example, 50% of the feedback signal 78 associated with both TE 534 can be preselected and TE 538. Obviously, any suitable portion of the feedback signal can be preselected. In some examples, you can pre-select 100% feedback.
[0055] For example, when the TE 534 corresponds to the shutter command for the camera application, the adaptive event recognition program 14 may preselect 50% of the data associated with the command and 50% of the image data to be provided to the user via the HMD device 42 to indicate that The image is captured. Similarly, when the TE 538 corresponds to the zoom command for the camera application, the adaptive event recognition program 14 can preselect 50% of the data associated with the zoom command and 50% of the image data to be provided to the user by the HMD device 42 to indicate that the camera is zooming .
[0056] In other examples, the adaptive event recognition program 14 may preselect at least a portion of the feedback signal 78 associated with one or more target events at other points in time that precede in time one or more target events along a time axis 302. For example, the adaptive event recognition program 14 may pre-select at least a portion of the feedback signal in the Detect3 414 state, which corresponds to PE 554 in FIG. 5, or in Detect1 406 state, which corresponds to PE 510 in FIG. 5.
[0057] In another example, when the user-related information 52 is consistent with a predictive pre-event that is not a selected target event, the adaptive event recognition program 14 may be configured to determine an estimated execution time when the selected target event occurs. For example, from the state of Detect2 410, the adaptive event recognition program 14 may receive user-related information 52 that is consistent with PE 554. PE 554 may be a predictive predictive event that corresponds to a predetermined probability that the target event TE 534 will subsequently occur.
[0058] With reference to FIG. 3, after matching the user-related information 52 with the predictive pre-event PE 554, the adaptive event recognition program 14 may determine the estimated execution time of the target event 534 when the event 534 occurs. In one example, the estimated execution time of the target event 534 can be determined referring to a predetermined estimated time interval illustrated by 340 in FIG. 3, between the detection of PE 554 and the occurrence of target event 534. As shown in FIG. 3, by summing the estimated time interval 340 with the actual detection time of the pre-event 554, it is possible to determine the estimated execution time of the target event 534.
[0059] Using the estimated execution time of the target event 534, the adaptive event recognition program 14 may provide a feedback signal 78 associated with the selected target event to the user either at the estimated execution time of the target event 534 or before the estimated execution time of the target event 534. In one As an example, feedback signal 78 may be provided at an estimated execution time of the target event 534, which may more accurately correspond to the actual time of the occurrence of event TE 534. Mostly, , the user may experience perceived delay which is substantially equal to zero, or possibly negligible.
[0060] In another example, feedback signal 78 may be provided before the estimated execution time of the target event 534 for a predetermined period of time. Advantageously, in this example, the user may experience a negative perceived delay when the feedback signal 78 is received by the user before the completion of the target event TE 534. In some examples, this may provide the user with improved perception of real-time interaction with the HMD device 42 and the adaptive event recognition system 10 . In some examples, providing feedback signal 78 to the estimated execution time of target event 534 can also be used to offset processing delays and / or other system delays and latencies that may be associated with providing feedback to the user through the HMD device 42. Thus, the delay associated with the feedback signal 78, which is perceived by the user, can be minimized.
[0061] In the above examples, it is obvious that any suitable sensor polling frequencies and the temporary development of increased polling frequencies can be used. Similarly, any suitable postures, gestures, or other hand movements can be indicated as pre-events and target events.
[0062] As mentioned above, it is also apparent that various other sensor systems can detect various other forms of user related information 52, and the HMD device 42 may transmit such information to the adaptive event recognition program 14. Such information may be correlated with other upstream events, patterns, and corresponding target events that relate to the information.
[0063] It is also apparent that the pre-events and patterns of FIG. 5 can be determined empirically through laboratory studies, user studies, or any other suitable methods. Estimated time intervals between the occurrence of pre-events and the execution of target events can be similarly determined by laboratory research, user research, or any other suitable means. When a selected target event is predicted, the threshold probability of occurrence of the selected target event after the penultimate pre-event can be used to reduce the occurrence of prediction errors. In some pre-event examples, target events, patterns, and estimated time intervals may be stored in high-capacity data storage 18 of computing device 22 or at a remote source accessible via network 16.
[0064] FIG. 6A and 6B show a flowchart of a method 600 for recognizing a selected target event according to an embodiment of the present invention. The following description of method 600 is provided with reference to the software and hardware components of the adaptive event recognition system 10 described above and shown in FIG. 1 and 2. Obviously, method 600 can also be implemented in other contexts using other suitable hardware and software components.
[0065] With reference to FIG. 6A, in step 604, the method 600 includes, in a display device comprising a plurality of sensors, using a selected sensor from a plurality of sensors at a first polling frequency corresponding to a higher potential delay. At 608, a plurality of input sensors can be selected from image sensors, position sensors, microphones, eye tracking sensors, and biometric sensors. At 612, the display device is a head-mounted display device.
[0066] At 616, method 600 may include receiving initial user related information from a selected sensor. At step 620, when initial user-related information is not received within a predetermined time frame, method 600 may include controlling a selected sensor to operate at an expired polling frequency that is lower than the first polling frequency. At step 624, method 600 may include determining whether the initial user-related information is consistent with one of a plurality of pre-events, each of the pre-events corresponding to one or more different pre-event patterns, and each of the patterns leads to a separate possible target event. At step 628, each of the templates may contain a separate sequence of pre-events.
[0067] In step 632, when the initial user-related information is consistent with one of a plurality of pre-events, method 600 may include using the selected sensor at a second polling frequency that is higher than the first polling frequency and which corresponds to a lower potential delay which is less than the higher potential delay. At step 636, after receiving the initial user-related information, the method 600 may include pre-sampling at least a portion of the feedback signal associated with the selected target event.
[0068] Now, with reference to FIG. 6B, after receiving initial information related to the user and before receiving subsequent information related to the user, at 640, method 600 may include receiving intermediate information related to the user from the selected sensor. At 644, method 600 may include determining whether intermediate information associated with the user is consistent with a pre-event from a subset of the many pre-events. At 648, when the user-related intermediate information is consistent with a pre-event from a subset of the many pre-events, the method 600 may include using a selected sensor at a third polling frequency that is higher than the first polling frequency and lower than the second polling frequency.
[0069] At 652, method 600 may include receiving subsequent user related information from a selected sensor. At step 656, when subsequent user-related information is consistent with the selected target event from various possible target events, method 600 may include providing a feedback signal associated with the selected target event to the user via a display device. At 660, the selected target event may include a hand gesture. At step 664, when subsequent user-related information is consistent with a predictive upstream event that is not a selected target event, method 600 may include determining an estimated execution time when the selected target event occurs. At step 668, the method may include providing a feedback signal associated with the selected target event to the user either at the estimated execution time or before the estimated execution time.
[0070] It is obvious that the method 600 is presented by way of example and not for purposes of limitation. Therefore, it should be understood that the method 600 may include steps additional and / or alternative to those shown in FIG. 6A and 6B. Additionally, it should be understood that method 600 may be carried out in any suitable order. In addition, it should be understood that one or more steps can be excluded from method 600 without deviating from the scope of this invention.
[0071] FIG. 7 schematically illustrates a non-limiting embodiment of a computing system 700 that can implement one or more of the above methods and processes. Computing device 22 may take the form of a computing system 700. Computing system 700 is shown in a simplified form.

Former principal spokesman for the 9/11 Commission Alvin S. Felzenberg discussed the legacy of political commentator William F. Buckley Jr. and his new book "A Man and His Presidents: The Political Odyssey of William F. Buckley Jr." on Nov. 13 at an event hosted by the Rebovich Institute for New Jersey Politics.
Felzenberg's interest in the conservative idol came about after Buckley's failed run for mayor of New York in 1965. A high school junior at the time, Felzenberg took a liking to Buckley's comedic take on a serious political race.
"Because of that campaign, I got my first glimpse of this fellow," he said. "He was asked what he would do if he was elected mayor of New York and he paused and said, 'Demand a recount.'"
Buckley went on to become one of Felzenberg's role models throughout his own political career, serving in two presidential administrations as advisor to the Departments of State and Defense, principal spokesman for the 9/11 Committee and director of communications for the Congress Joint Economic Committee.
Now, Felzenberg teaches at the University of Pennsylvania Annenberg School for Communication where he says his students are his biggest influencers.
He recalled the day Buckley died in 2008 when he asked his students if they knew of the commentator.
"The week that I was giving my first lecture, William F. Buckley passed away," he said. "I started by asking how many of them had actually heard of William F. Buckley Jr. I was astonished when all the hands went up. So I said, 'Who was he?' I was met with complete silence. I said, 'What did he do?' They just stared at me. Then I asked, 'Well, why did you raise your hands?' It turned out they were all getting email blasted to death by news outlets that William F. Buckley had died."
Instead of being disappointed by his students' lack of knowledge, Felzenberg used the situation as a learning opportunity to illustrate Buckley's successes in the political world.
"I decided to write this book for them," he said. "We had so much fun with him the first time around, why not bring him back for a whole new generation?"
Felzenberg took the audience through Buckley's entire career, emphasizing his wide range of career highs including his long-running magazine column detailing his conservative views and his even longer running talk show Firing Line.
"He dominated every form of communication that was available in his era," he said. "He dominated the world of magazines. He brought forth the first column by a conservative called On The Right. He was writing his last column when he passed away and left behind over 500 columns. He was also a master of public television and public debate. Firing Line ran 33 years in public television, and it was the longest running public affairs show by the same host."
Felzenberg also stressed that Buckley lived during a different, more exhilarating time of politics.
"This was a time where politics were fun," he said. "Politics were civil and his form appealed to the people of the United States because he tried to teach us things. We left lecture halls better informed than when we went in."
Director of the Rebovich Institute for New Jersey Politics Ben Dworkin appreciated Felzenberg's dedication to enlightening younger audiences on Buckley's views.
"To have somebody in the [President Donald] Trump era who can talk about intellectual conservatism, what its legacy was, the person who really drove that William F. Buckley Jr. and how it might manifest itself in the future. It's an important thing," Dworkin said.
