Abstract
Tactile feedback is widely used to enhance realism in virtual reality (VR). When touching virtual objects, stifness and roughness are common and obvious factors perceived by the users. Furthermore, when touching a surface with complicated surface structure, differences from not only stifness and roughness but also surface height are crucial. To integrate these factors, we propose a pinbased handheld device, HairTouch, to provide stifness diferences, roughness diferences, surface height diferences and their combinations. HairTouch consists of two pins for the two fnger segments close to the index fngertip, respectively. By controlling brush hairs' length and bending direction to change the hairs' elasticity and hair tip direction, each pin renders various stifness and roughness, respectively. By further independently controlling the hairs' confguration and pins' height, versatile stifness, roughness and surface height diferences are achieved. We conducted a perception study to realize users' distinguishability of stifness and roughness on each of the segments. Based on the results, we performed a VR experience study to verify that the tactile feedback from HairTouch enhances VR realism.
