We introduce a novel virtual reality (VR) ride system consisting of a head-mounted display (HMD), an electric wheelchair and an electric wheeled ramp as an amusement park attraction. The electric wheeled ramp which is a customized electric wheelchair can carry a user wearing an HMD and is able to control its speed, acceleration, and orientation. This system presents the sense of continuous moving on a slope and the sense of movement on a slope with varying curvatures in the ascending and descending experiences, thus amplifying the perception of virtual ascent and descent.

We proposed a VR game named ''Boomshin'' using an encountered-type haptic display and investigated the effects of switching the presence of haptic feedback for objects in the VR space over time. We named objects with and without haptic feedback as ''real entities and ''clones respectively, and evaluated the impression of the VR game experience under the various temporal presentation patterns of them. The results showed that the players' surprise and satisfaction were higher when real entities and clones were mixed than when only real entities or clones appeared. In addition, a sudden change in the frequency of appearance of real entities brought an impression impact.
