Holo-Haptics: Haptic interaction with a see-through 3D display

In this paper, we present Holo-Haptics, which is an interactive haptic system to provide the illusion of touch that users are interacting directly and intuitively with 3D virtual contents. In order to provide haptic feedback, we use a thimble-formed pneumatic balloon display. It allows users to feel tactile sensation of contact, direction, and movement.
