Finger detection based on data fusion of fish-eye stereo camera for 3D-gesture input interface

There is a growing importance of the in-air hand operation for the input devices. In order to introduce such in-air operation, we require an image sensing technology that enables 3D position detection of the user´s hand in wide range. In this paper, as a practical application system, we focus on the Zooming Touch Panel [1] that connects the touch-panel and in-air operations seamlessly. In order to provide wide operation space for this type of the system, we propose a new hand detection method based on data fusion of fish-eye stereo camera. This technique enables both high-accuracy and wide-range 3D hand detection. Also this paper shows two example demonstrations.
