In this paper, we explore the effects of multimodal haptic feedback combining vibrotactile and electrical muscle stimulation (EMS) on expressing virtual collisions. We first present a wearable multimodal haptic device capable of generating both mechanical vibration and EMS stimuli. The two types of haptic stimulus are combined into a haptic rendering method that conveys improved virtual collision sensations. This multimodal rendering method highlights the strengths of each modality while compensating for mutual weaknesses. The multimodal rendering method is compared in subjective quality with two unimodal methods (vibration only and EMS only) by a user study. Experimental results demonstrate that our multimodal feedback method can elicit more realistic, enjoyable, expressive, and preferable user experiences. #haptics #haptics2024 #multimodal #vibrotactile #ems
