Abstract

We have proposed a finger indexing interface for distance lectures. We have developed an algorithm to measure where on a monitor or display is pointed at by using a stereo camera pair. In this paper, we have evaluated the accuracy of the measurement algorithm. As experimental results, about 85% of finger indexing positions are correctly measured if a user stands in front of the monitor and his index finger is 1 meter far from there. When he stands in front of but at an oblique angle to the monitor, the algorithm sometimes causes errors.
