PhantomTouch: Creating an Extended Reality by the Illusion of Touch using a Shape-Memory Alloy Matrix
SIGGRAPH Asia 2019 XR(2019)
摘要
With the rise of VR applications, the ability to experience physical touches becomes progressively important to increase immersion. In this paper, we propose PhantomTouch, a wearable forearm augmentation, that enables recreation of natural touch sensation by applying shear forces onto the skin. In contrast to commonly used vibration-based haptics, our approach consists of arranging light-weight and stretchable 3 × 3cm plasters in a matrix onto the skin. Individual plasters were embedded with lines of shape-memory alloy (SMA) wires to control shear forces.
The matrix arrangement of the plasters enables the illusion of a phantom touch, for instance, feeling a wrist grab or an arm stroke.
