3D Virtual Hand Selection with EMS and Vibration Feedback

Abstract

Selection is one of the most basic interaction methods in 3D user interfaces. Previous work has shown that visual feedback improves such actions. However, haptic feedback can increase the realism or also help for occluded targets. Here we investigate if 3D virtual hand selection benefits from electrical muscle stimulation (EMS) and vibration. In our experiment we used a 3D version of a Fitts' task to compare visual, EMS, vibration, and no feedback. The results demonstrate that both EMS and vibration are reasonable alternatives to visual feedback. We also found good user acceptance for both technologies.
