Effects of Vibrotactile Feedback in Commercial Virtual Reality Systems
This study investigates the effects of vibrotactile feedback by motion controllers of a commercial virtual reality (VR) system on immersion, actual and perceived user performance, and perceived difficulty of specific tasks in VR.
To this end, we developed two different tasks in VR with different types of interactions: entering numbers by rotating a number dial and stirring a pot. In a within-subject experiment, 14 participants completed the two tasks with and without vibrotactile feedback.
The results showed that for both tasks self-reported immersion was significantly improved by vibrotactile feedback, while perceived difficulty was significantly reduced for one task, and perceived performance was significantly increased for the other task. These results show that even the limited vibrotactile feedback by motion controllers of commercial VR systems is capable of significantly changing VR experiences.
