 In this paper, we explored the effects of multimodal haptic feedback combining vibrotactile and electrical muscle stimulation on expressing virtual collisions. To express virtual collisions, we first decomposed collision responses into force and vibration. Then, we used EMS and vibration to represent both components, respectively. We presented a wearable multimodal haptic device generating both mechanical vibration and EMS stimuli and designed a haptic rendering method. We applied it to two sports, boxing and tennis, and conducted the user study.
