Camera Phone Based Interaction Methods

TinyMotion published by Jingtao Wang and John Canny on Group for User Interface is a pure software approach that detects the movements of cell phones in real time by analyzing image sequences captured by the built-in camera.

Typical movements that TinyMotion detects include - horizontal and vertical movements, rotational movements and tilt movements. As a result, a user can activate and access different functions of a phone (for example, scrolling and selecting the phone menu, Zooming in/out pictures, Moving an on-screen cursor to a given region and even gesture/handwriting input) by moving, tilting or rotating the phone.

Different from existing research work, TinyMotion does not require existing research work and can run on today’s main-stream camera phones without hardware modification. Even more, TinyMotion can detect camera movement reliablely under diverse background and illumination conditions.
