CSI, Minority Report, and many sci-fi films and TV series all show
gesture control of computers. This of course for now available for
videogames and computers but smart phones have been left out because the
processing power requirements, until now.
Professor Otmar Hilliges and his staff at ETH Zurich have developed
an app for smartphones that uses the front camera to capture hand
gestures to control various functions of any smartphone. It uses less
processing power because it simplifies the process of recognizing the
gestures by creating an outline of the various hand positions.
The program also recognizes the distance of the hand from the camera
and warns the user it they are too far or too close. Currently the app
recognizes six different hand gestures that execute their corresponding
commands, but more can be added later. The requirements for the gestures
to work is that they have to be clearly defined to make a good outline
to be easily recognized.
Soon people will be waving their hands at their smartphones while
walking down the street as well as talking full volume to no one in
front of them! This app is meant to augment the functions of smartphones
and not replace the touchscreen.
