Altering resistive force perception by modulating velocity of dot pattern projected onto hand

In this paper, we explore the possibility of altering user's resistive force perception by using pseudo-haptics in spatial augmented reality. Through a psychophysical experiment, we investigated the effect of changing the velocity of a dot pattern projected onto a participant's hand during the resistive force perception. A statistical analysis of the result reveals that the speed of the dot pattern movement affects the perceived force such that a faster movement makes participants feel a smaller force, and the direction of the movement has no effect.
