Abstract :
Most of the current laser pointing interfaces use a vision based approach, which requires camera calibration. This paper presents the use of a planar homography-based auto-calibrated technique to eliminate the camera calibration step, thus simplifying the setup process. The system performance of a user interface implemented with this technique is then analyzed in details.
