Charrot: Pseudo-haptics with Mid-air CG Character and Small Robot

We propose Charrot, a novel pseudo-haptic approach for interaction with computer-generated (CG) characters that are displayed by mid-air imaging technology. Pseudo-haptic approach is based on the combination of the visual representation of the CG character movement and the vibrotactile cues. The vibrotactile cues are generated by a small robot that can be easily handled by children. We designed the movements of a CG character pushing or pulling the small robot. Experiments have been carried out to evaluate the interaction between the visual representation of the CG character movements and the vibrotactile cues. The results showed that the visual representation of the CG character movement can change the direction of the perceived force. We demonstrated a game that allows to interact with the CG characters using pseudo-haptics at the open campus of the University of Electro-Communications.
