Abstract:
In this presentation, we report on recent facets of our ongoing research on a wayfinding device for visually impaired or blind travelers. We summarize previous efforts using virtual (spatialized) sound, spatial language, and several direction/distance giving information processes. Based on our experiences with Remote Infrared Auditory Signage (RIAS), a haptic device was developed to provide directional guidance. Experiments were undertaken to explore the relative effectiveness of spatialized sound (tones), verbal prompts, and vibratory stimuli as guidance techniques. A more detailed discussion of the vibratory deice is then provided together with suggested ways of testing the effectiveness of each interface.
