Abstract

Tabletop hand tracking techniques have evolved much during the last few years from single to multiple cameras, offering users an improved interactive experience. MirrorTrack is one of such techniques. This paper demonstrates the comparison of accuracy between MirrorTrack and top-down approach, which is generally used for table top tasks. In this paper, we focus on the comparison of distance errors in finger trajectory, and clicking errors by manual monitoring.
