Design of force feedback utilizing air pressure toward untethered human interface

In order to apply VR technologies to tools for everyday life, it is necessary to develop human interface technologies that do not constrain the users' activities. To achieve this goal, we propose a new force feedback method that utilizes air pressure to provide a force sensation to users. This force feedback system does not constrain users by an arm or a wire that connected with devices, and allows users to move their bodies and hands freely. This paper introduces the concept and the initial implementation of the air-pressure-based force feedback system.
