Visuo-Haptic Display Using Head-mounted Projector

This paper proposes a novel ‘Visuo-Haptic Display’ using a Head-Mounted Projector (HMP) with X’tal Vision optics. Our goal is to develop the device which enables an observer to touch a virtual object just as it is seen. We describe the detail design of an HMP with X’tal Vision, which is very suitable for Augmented Reality. For instance, the HMP makes almost-correct occlusion relationship between the virtual and the real environment. Accordingly, the observer can observe his/her real hand with the virtual objects. Furthermore, the HMP reduce eye fatigue, because of low inconsistency of accommodation and convergence. Therefore, we applied HMP-model 2 to a visuo-haptic displays with the camouflage technique. This technique is called Optical Camouflage. This technique makes an obstacle object like a haptic display become translucent. By using this method, a user can observe a stereoscopic virtual object with almost-correct occlusion relationship between the virtual and the real en...
