Description

This paper describes design of a surface type haptic interface for presentation of hardness distribution in an elastic object. The haptic interface is composed of an elastic plate and a linear actuator array. It provides a spatially continuous surface on which users can effectively touch virtual objects using any part of their bare hand. The elastic plate is made of rubber and sponge. When the actuator pushes the plate, its hardness increases. The user feels as if hard object is submerged in a soft object. We analyze the performance of the device through measurements of rigidity and psychophysical tests.
