Max Pfeiffer was at the IEEE VR talking about a demo where he’s experimenting with off-the-shelf Electrical Muscle Stimulation (ESM) message devices in order to provide haptic feedback for pointing with your hand within 3D virtual environments. He’s tracking the hands with a depth sensor camera to detect finger pointing, and then providing haptic feedback on the arms to stimulate a subtle haptic feedback. He did a Fitts’ Law analysis of the efficiency of this technique, and he found that “results demonstrate that both EMS and vibration provide reasonable addition to visual feedback. We also found good user acceptance for both technologies.”
