Investigating the Effect of Targets’ Spatial Distribution on the Performance of Gesture Interaction in Virtual Reality Environment

In virtual reality(VR) environment, how to accurately and effectively select target objects is an important part of interactive tasks such as virtual simulation and virtual assembly. Gesture is one of the most crucial interaction technologies in human-computer interaction. This study conducted a multi-factor experiment in VR environment to explore the effects on the performance of pointing task under different depths and different perspectives. Participants need to point to the target objects in different viewing angle areas at different depth levels with HTC-Vive headset and Noitom HI5 gloves. The results show that the higher the depth level and the closer the target is to the visual center, the higher the pointing accuracy, and the pointing deviation is smaller on the dominant hand side than the non-dominant hand side. The research results have reference value for the spatial distribution of target objects for gesture interactive tasks in VR environment.
