Analysis of tactual impression by audio and visual stimulation for user interface design in mixed reality environment

Abstract

In a mixed-reality (MR) environment, a touchable object can be made to change its appearance when a computer-generated image (MR visual stimulation) is superimposed onto it. In this research, we conduct experiments to study the effects of MR visual and audio stimuli on the tactual impression of the "roughness" of an object. We show that MR visual stimulation alters a subject's tactual impression of the roughness of an object and that the addition of MR audio stimulation intensifies that effect. © 2009 Springer Berlin Heidelberg.
