Preliminary investigation of the impact of visual feedback on a camera-based mouse-replacement system

This paper reports the design, implementation, and results of a carefully designed experiment that examined the performance of a camera-based mouse-replacement interface that was supported with visual feedback. Four different visual feedback modes were tested during the pointing-task experiment. Quantitative results, based on three metrics, do not show statistically significant difference between these modes. Qualitative feedback from the participants of the experiments, however, shows that user experience is improved by static and animated visual feedback during the pointing task.
