Virtual ISU: locomotion interface for immersive VR gaming in seated position

Abstract

This paper describes a new locomotion interface suitable for immersive virtual reality (VR) gaming in a seated position. In the proposed approach, the user can roam in virtual space while sitting on the Virtual Intuitive Striding Unit (ISU). This device is equipped with pressure sensors in a seat cushion. The sensors detect the user's leg and body movements to estimate walking direction and speed. With Virtual ISU, sensors are not attached to the user's body or the floor and can be used various people, including the elderly and physically handicapped.
