Examination of Experience Improvement Effects on Impact-like Motion Feedbacks Added on a Virtual Reality Entertainment System Using a Car

Abstract

We are developing a virtual reality entertainment system using a car as a motion platform. The feasibility and usefulness of this system has been evaluated on prototypes based on an electric car. However, the prototype has two problems, one is feeling of mismatch between the images and the movements, and the other is lack of realism for situations with shaking. As these issues were supposed to be caused by limited bandwidth of the car motion, we propose to add vibrators on the system and to combine the car movement with the vibrotactile stimulus. The vibrators expand the frequency limit of vibration stimulus by the car, as well as the car movement itself compensates the lack of the vibrators' power. The results of user evaluation showed that the mismatches were reduced and the shaking feeling was improved.
