Applying "Out Of Body" Vibrotactile Illusion To Two-Finger Interaction For Perception Of Object Dynamics

Vibrotactile feedback is an effective and economical approach for enriching interactive feedback. However, its effects are mostly limited to providing supplementary alarms or conveying the sense of simple object presence or contact. We propose to apply the "out of body" tactile illusion for selecting and manipulating a virtual moving object while also being able to feel its dynamics using two fingers. We assessed the user experience (focusing on the perception of the dynamics of the selected object) of the proposed method by comparing it to the conventional contact-based method. Our results indicate that users were able to perceive the dynamic feedback, and preferred it over the conventional method.
