> it opens the door for bleeding-edge to aim for larger detection distances, and eventually seeing hand gestures above the screen [...] our screen interactions need to be broadened [...] signal intent but not commitment (like hovering with a mouse, or looking with eye tracking) My laptop used to have several cameras (flopping up from behind screen) for 3D hand tracking, (crufty) keycap touch, and head/gaze pose. With shutter glasses, overlaying a slightly-raised transparent top-down view from a keyboard cam was helpful and tolerable. Browser-based stack. Input fusion with diverse latencies required app state rollback. Fun(ish). > _finally_ [...] even that got dropped a few years back [...] eventually [...] broadened This was profoundly frustrating. Waiting for a couple of giant companies, interested only in extremely difficult mass consumer markets, to make tech available so it can afterward be explored and nitches probed, with patents shackling everyone else, was just... sigh. Pharma turning the nation's explore-exploit dial hard over regrettably leaves a lot of paths forward nonviable.
