Why has this not taken off? Off-the-surface gestures seem like they'd really enrich smartphone experience. I don't get why this low power proven tech has not been incorporated into phones. It's already 8 years old!

Why do you think it's not in use? Microchip calls it a "capacitive touch sensor" IC on their website. Plenty of phones have that.

Really? This one is a 3D sensor. Off-the-screen gestures. Have you seen people making gestures above the surface of their phones?

I haven't seen that. Why hasn't it happened yet?

edit: Anywho, let's check the Microchip website. They don't call it what you said. There's no capacitive touch on its page, just the title. It's all 3D e-field. I think you must have got the wrong chip. Where did you see it?

A slightly different take, Google Soli (in-phone radar), is in the Pixel 4.

Hope to see an wristband which recognizes hand gestures soon. Together with smartphone head tracking it could open the window to useful everyday AR.
