Obtaining geographical information from a virtual map with a haptic mouse

Abstract

The aim was to investigate the potentials of obtaining geographical information from a virtual map with the VTPlayer, a haptic mouse with two matrices of 4x4 pins, one for each of two fingers. The experimental task was to find the location of states on a USA map under two conditions: with or without tactile matrix information. In both cases auditory and kinaesthetic information was available. The result was that the tactile matrix information had no effect. During the study several general problems with a haptic mouse for users deprived of vision were noted. It is, for example, difficult to navigate with a mouse without visual feedback and the tactile information is very limited. In spite of the problems encountered with the haptic mouse and its software, it may be worthwhile to investigate the possibilities of improvements, not the least because of the participants enjoyment and expectation of its usefulness. Some possible improvements are discussed.
