Tilt Control developed by Isobar, is a Google Glass app that proves to be advantageous for mobility-impaired individuals, allowing them to make full use of the entire Glass experience through head tilts and winking. When voice commands are not readily available, users can navigate system controls in a far more comprehensible way.
For instance, users can turn on the Glass screen with a single wink, or tilt their head to the left or right to scroll through the timeline in that direction. To prompt users of command acceptances, the app will sound a little knock after each request.
Mike DiGiovanni, designer of Tilt Control, highlighted some technical considerations for potential contributors on GitHub, with emphasis on device reboots and user-friendliness.
