A capacitive "touch sensor" is pretty much the same as a proximity sensor, just tuned to the touch surface, so I don't think that could be much of a problem. Just put the sensor plane behind the keys.
BTW, I've seen a keyboard prototype that used capacitive sensing of the user's fingertips as the key-actuation method. By doing that, the trackpad/keyboard might be even simpler.
- bogwog 4y agoYeah but the keys/switches themselves could become damaged by pushing them side to side. Maybe on a low height keyboard on a laptop it’s less of a problem, but trying to swipe my fingers across my mechanical keyboard and my X1 Yoga keyboard definitely feels like I’m going to break something. The BB Passport had almost no gaps between the keys, so it felt like a continuous, slightly bumpy surface. I don’t think that’d work well on a larger form factor, but maybe I’m wrong.
