A robust finger pointing interaction in Intelligent Space

In this paper, we proposed a pointing interaction system which allows users to control devises in Intelligent Space by using hand pointing. This system consists of multiple camera devices and a pan-tilt projector. This system recognizes user´s face, user´s head orientation and a spot where user points with the camera devices. However, to achieve a real interaction, an intuitive feedback is required to let a user know what the Intelligent Space recognizes. We placed a pan-tilt projector in Intelligent Space and we developed an intuitive feedback method based on user´s location. The experimental results show the performance and the validity of the proposed system in this paper.
