QuadStretch: A Forearm-wearable Skin Stretch Display for Immersive VR Experience

Force feedback is important for immersive VR experience but requires a cumbersome device restricting the use of the hand. An alternative to work around this problem is the use of substituted tactile feedback. QuadStretch is a lightweight and flexible forearm-wearable device for providing substituted skin-stretch feedback to express force on the arm. Consisting of four pairs of tactors, it does not require a ground point and can express the directional sense of force accompanying arm movements. In this demo, we prepared six demo scenarios, Boxing, Archery, Wings, Climbing, Slingshot, and Fishing, to show how the expressive power of QuadStretch can enhance the VR experience.
