Tabletop virtual haptics

  • When thinking of Virtual Reality (VR), most people think of stunning audio-visual environments in the context of entertainment. However, VR can also provide haptic information, e.g., to convey spatial information to blind and visually impaired people. In this context of accessibility they might be able to explore independently and self-determined tactile graphics, e.g., the structure of unknown real places prior to visiting them. Thus, we propose and evaluate tabletop virtual objects that can be felt by nowadays commercially available VR components, instead of exploring physical models (e.g., 3D printed maps) with the bare hand. These can be easily placed on an empty table, giving the blind user faster and more independent access to tactile information than with real physical representations. Our comprehensive pilot user study shows that it is possible to recognize floor plans and simple geometric shapes in this context. Also, the insights gained with regard to the suitability for practical application in this context point out theWhen thinking of Virtual Reality (VR), most people think of stunning audio-visual environments in the context of entertainment.
