Image-based finger pose measurement for hand user interface

This paper presents image-based finger pose measurement for hand user interface. The aim of this measurement technique is to make a better user interface enabling three dimensional operation by hand. The measurement technique uses stereo vision, and approximates the hand motion based on anatomical constraints. Distinctive feature of the measurement technique is usage of ring markers, which enable to determine the position and direction of the finger link where the marker put on. The appropriateness of the measurement technique is evaluated through experiments.
