Abstract

This paper presents the first results on a user study in which people with visual impairments (PVI) explored a virtual environment (VE) by walking in a virtual reality (VR) treadmill. As recently suggested, we have now acquired first results from our feasibility study investigating this walk-in-place interaction. This represents a new, more intuitive way of for example virtually exploring unknown spaces in advance. Our prototype consists of off-the-shelf VR components (i.e., treadmill, headphones, glasses, and controller) providing a simplified white cane simulation and was tested by six visually impaired subjects. Our results indicate that this interaction is yet difficult, but promising and an important step to make VR more and better usable for PVIs. As an impact on the CHI community, we would like to make this research field known to a wider audience by sharing our intermediate results and suggestions for improvements, on some of which we are already working on.
