WEARABLE HAPTIC DISPLAY FOR IMMERSIVE VIRTUAL ENVIRONMENT

抄録

Recently a number of immersive displays that project virtual environment on large-sized screens have been developed. In applications of virtual reality technology for such large immersiveenvironments, it is important to develop some haptic display that gives a real feedback sensation such as forceor tactile to users from the virtual environment. Especially, it is necessary to develop small, light and safety actuators for the wearable haptic display. In this paper, the haptic display system using pneumatics for theimmersive virtual environment is proposed and developed. The system consists of a tactile and a force reflecting type wearable haptic displays using pneumatic pressure control. Experiments for grasping virtual objects in the virtual environment are performed by the wearable haptic displays using pneumatic actuators. It is experimentally verified that the performance of the haptic display system is effective to touch and grasp the virtual objects.
