Haptopus: Transferring the Touch Sense of the Hand to the Face Using Suction Mechanism Embedded in HMD

Along with the spread of VR experiences by HMD, many proposals have been made to improve the experience by providing tactile information to the fingertip, but there are problems such as difficulty in attaching and detaching and hindering free movement of fingers. As a method to solve these issues, we developed Haptopus, which embeds the tactile display in the HMD and presents tactile sense associated with fingers to the face. In this paper, we conducted a preliminary investigation on the best suction pressure and compared with the conventional tactile presentation approaches. As a result, it was confirmed that Haptopus improves the quality of the VR experience.
