Lateral Touch Detection and Localization for Interactive, Augmented Planar Surfaces

摘要

This work regards fingertip contact detection and localization upon planar surfaces to provide interactivity in augmented displays implemented upon these surfaces, by projector-camera systems. In contrast to the widely employed approach where user hands are observed from above, lateral camera placement avails increased sensitivity to touch detection. An algorithmic approach for the treatment of the laterally acquired visual input is proposed and is comparatively evaluated against the conventional.
