Effect of Vibrotactile Feedback on Simulator Sickness, Performance, and User Satisfaction with Virtual Reality Glasses.

This study investigated the effects of vibrotactile feedback on simulator sickness, human performance, and user satisfaction when wearing virtual reality glasses. A total of 36 participants were recruited and 30 of them finished the experiments. They were asked to wear virtual reality glasses to play a car race game with a vibrotactile vest and a vibrotactile gamepad. The vest and gamepad provided vibration feedback, which was turned on in one task and turned off in the other task. The performance was measured during the tasks and simulator sickness and satisfaction were measured through questionnaires. The results showed that the participants suffered severe simulator sickness without vibrotactile feedback and they were more satisfied with vibrotactile feedback. However, there was no significant difference observed in terms of performance. This study suggested that virtual reality glasses with vibrotactile feedback would improve the user experience. The result can help VR developers to choose proper vibrotactile feedback in VR applications.
