The machine was rather difficult to operate. For years radios had been operated by means of pressing buttons and turning dials; then as the technology became more sophisticated the controls were made touch-sensitive--you merely had to brush the panels with your fingers; now all you had to do was wave your hand in the general direction of the components and hope. It saved a lot of muscular expenditure, of course, but meant that you had to sit infuriatingly still if you wanted to keep listening to the same program.&lt;p&gt;&amp;gt; Zaphod waved a hand and the channel switched again.&lt;p&gt;&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;www.technovelgy.com&amp;#x2F;ct&amp;#x2F;content.asp?Bnum=1329&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.technovelgy.com&amp;#x2F;ct&amp;#x2F;content.asp?Bnum=1329&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>Google wins U.S. approval for radar-based hand motion sensor</title><url>https://www.reuters.com/article/us-google-sensor/google-wins-u-s-approval-for-radar-based-hand-motion-sensor-idUSKCN1OV1SH</url></story>

Gestures are extremely unintuitive on their own. Users need really clear prompts and&amp;#x2F;or training to understand how to use them. And if you want to innovate and create new and subtle gestures as your product evolves, it only gets worse.&lt;p&gt;The leap motion is already pretty good and has some useful applications, but it&amp;#x27;s still very, very niche. The Soli looks like a real evolution of the technology in terms of both precision and how embeddable it is, but it&amp;#x27;s going to have the same challenges in user adoption. I&amp;#x27;d expect this kind of thing to get more traction in industry than in people&amp;#x27;s homes.</text><parent_chain></parent_chain></comment><story><title>Google wins U.S. approval for radar-based hand motion sensor</title><url>https://www.reuters.com/article/us-google-sensor/google-wins-u-s-approval-for-radar-based-hand-motion-sensor-idUSKCN1OV1SH</url></story>
