Just got to see some google effort at using the facial recognition tech to interpret a touchless interface based on hand gesturing in the space between user and device.
my iPad knows me, the device sort of checks to see if I'm paying attention. In the evening sunshine on Kings Way Bowling Lawn, and the screen brightness really low; you can see yourself reflected. If you touch your nose, that's as far forward as is sensible to go in that direction; the interaction space is the area from your nose to the visual display associated with your gaze.
