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!
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?
