The second one seems more of a technical one and can be solved if Soli can reliably recognize user attention, which can effectively be a "hotword" for gesture.

The second one seems more of a technical one and can be solved if Soli can reliably recognize user attention, which can effectively be a "hotword" for gesture. This is hard and not sure even it's feasible with this tech, but given all the excitements in this thread on potential privacy issues I guess it's doable :D The first one seems more troublesome. This is less intuitive than touch screen based interface. The only way I see fighting against this is to standardize a set of generic gestures, map onto existing equivalent touch/voice actions and push it to the Android ecosystem. But not sure how many third party manufacturers will join this parade. Does this technology work well under screen? The industry is now obsessed with getting rid of notch and if Soli blocks this path then it will be a pretty hopeless fight.
