ElasticVR: Providing Multi-level Active and Passive Force Feedback in Virtual Reality Using Elasticity

摘要

We propose a light-weight, wearable device ElasticVR to provide various force feedback in multi-level in virtual reality (VR) for more immersive and realistic VR experiences. Force feedback is generally categorized into passive and active force feedback. Passive force is produced passively and continuously against the body part movement, e.g., elasticity and resistance. Active force is triggered by events and rendered actively and discretely to stimulate users, e.g., recoil and impact. ElasticVR consists of an elastic band, servo motors and mechanical locks to provide both passive and active force feedback. By changing length and extension distance of the elastic band, different elasticity levels produce various force feedback levels. By observing multi-level force feedback perception, we provide 5-level passive and 3-level active force feedback on the finger. We expect that realistic force feedback from ElasticVR enhances VR experiences.
