Grip Comfort Study of Virtual Reality Handles

Virtual reality (VR) devices are increasingly being utilized in a variety of scenarios. The aim of this study was to investigate the grip comfort of VR handles in different scenes. Thirty-two representative participants were recruited for the study, and three different VR handles, including the O-shaped, H-shaped and I-shaped, were evaluated. Four dimensions of grip comfort were subjectively rated by the participants in both dynamic and static scenes, and subjective interviews were conducted. A high-precision 3D scan was performed on the participants' grip posture, and the Average-Hand was determined from the scan results. The fit of the product was analyzed through a deviation analysis test, which was combined with the subjective rating method to obtain visualization of the human-product fit results. It was found that in the dynamic scene, larger handles such as the H-shaped handles provide better stability and grip comfort. In static scene, handles with a better distribution and smaller dimensions such as O-shaped and I-shaped handles provide less pressure and fatigue and thus better grip comfort.
