Quantitative analysys of pseudo-haptics based on three types of hand form and two phases of perception

Haptic media, as a third type of 3D media besides 3D visual and 3D audio, is essential to realize the true 3D multimedia. Recently, pseudo-haptics has gained considerable attention since it can produce a haptic feeling without specific hardware. We first categorized pseudo-haptics into three types based on perception phases and virtual hand form. A series of experiments quantitatively proved that all three types of pseudo-haptics can be perceived and exhibit interesting phenomena, e.g., pseudo-haptics might be deduced by real haptic sensation or specific visual effect.
