[Letter] Pseudo-haptic Sensation Elicited by Background Visual Motion

Abstract

Haptic interaction techniques based on visual feedback have been proposed. The primary principle of presenting the pseudo-haptic sensations is to change the ratio between displacement of user's input and visual displacement of its indicator. Here I report that a pseudo-haptic sensation can also be produced simply by modulating the speeds of background visual images, without changing the movement of visual indicator itself. In this work, I performed two psychophysical experiments to study dominant parameters for generating the pseudo-haptic sensation elicited by background visual motion.
