A finger pointing system is described that can specify the position of a pointed target. A 3D position is generally detected and measured using stereoscopic images of multi-lens camera system. This pair of stereo images allows us to obtain the 3D information about the object. However it is possible to estimate the position of fingertip using a single image without stereo images. The geometric model of human gives estimates of the length of an arm and the 3D position of a fingertip. We approximately find out the length of an arm from stature and shoulder lengths, then the 3D position of a fingertip is estimated using the geometric model. We have developed a prototype finger pointing system using a single camera and a personal computer. This paper proposes the measuring method of the positions of finger and pointed target using a single camera.
