Abstract
In order to construct virtual environments, 3D displays using retinal disparity have been employed in most of the system. However, depth perception of virtual objects with such displays is known different from that of real objects, due to the unbalance of ophthalmic accommodation and convergence. In this study, we developed a device providing depth cue by use of haptic phantom sensation elicited by mechanical vibrators in order to handle virtual objects. The depth cue is mapped to the position of the phantom sensation. Operators' task performances with this device to move and deform virtual objects were measured, and the effectiveness of the device related to 3D information display methods are discussed.
