Discrimination of tactile rendering on virtual surfaces

Abstract
An array of vibrating contactors on the fingertip can provide information about virtual objects during active exploration of a virtual environment – for example, information about contact area, edges, corners and surface texture. For the operation of such a device, it is necessary to generate in real time an individually specified drive waveform for each contactor of the stimulator array. To reduce the complexity of the problem, a system has been developed at Exeter in which each drive

signal is specified as a mixture of a small number of sinewaves.

An array of vibrating contactors on the fingertip can provide information about virtual objects during active exploration of a virtual environment – for example, information about contact area, edges, corners and surface texture. For the operation of such a device, it is necessary to generate in real time an individually specified drive waveform for each contactor of the stimulator array. To reduce the complexity of the problem, a system has been developed at Exeter in which each drive

signal is specified as a mixture of a small number of sinewaves.



The aim of this study is to investigate the discrimination of the virtual textures which can be produced in this way, with the aim of developing a library of textures for use in virtual reality applications. Textures produced by mixtures of sinewaves are differentiated in terms of the mean amplitude and the spatial distribution at each sinewave frequency. Experimental questions include

the number of categories (i.e., requency/amplitude/spatial combinations) that can be distinguished and the possible correspondence between virtual and real textures. (Less)
