Image projection to the Volumetric Haptic Display

Abstract

This paper describes image projection to the volumetric haptic display. The volumetric haptic display can represent a physical characteristic of 3-D virtual objects, such as shape and elasticity, as a real object in the real world. We try to project image around this 3-D object with using projector and create integrated environment that contains haptic information and visual sense, but there are two problems. One is distortion of the image on the screen, and the other is that the image has been projected on the user's hand during interaction. These problems destroy the feeling of unity in the haptic information and visual sense. To solve them, we approached distortion collection method using simulator and image extraction method using rotary mechanical shutter. Experimental result shows that these methods enable more natural projection.
