UWB stuff might benefit here by providing a reference point to anchor virtual objects to (e.g. saving a position and orientation relative to the physical chip in the car).</text><parent_chain><item><author>icanhackit</author><text>It feels like this is the key to unlocking useful AR [1] for low powered, lightweight headsets. If the heavy lifting for locating and interacting with objects in 4D space is done with UWB, you don&amp;#x27;t need to do too much computational heavy-lifting - reducing bulk, increasing available space for batteries and reducing battery draw.&lt;p&gt;[1] Right now I can&amp;#x27;t really see a killer app for AR, something that would make you super-human enough to want a layer of abstraction between you and the real world. However if I could remotely interact with objects through walls, like turning off a lamp in a bedroom or seeing where my wife is and opening up a audio chat with her so that we&amp;#x27;re not yelling to hear each other, all of a sudden the trade off of having to charge and wear another device seems less annoying. All of a sudden you have powers not unlike a sorcerer.</text></item></parent_chain></comment><story><title>The U1 chip in the iPhone 11 is the beginning of an Ultra Wideband revolution?</title><url>https://sixcolors.com/post/2019/09/the-u1-chip-in-the-iphone-11-is-the-beginning-of-an-ultra-wideband-revolution/</url></story>
