Jason Morris, Tom Elliot, Thomas LoganSpatial information is often presented in the form of maps that viewers actively explore to learn about an area. People who cannot see cannot share the benefits of such a visual representation, and have traditionally relied on audio descriptions, tactile maps, guidance from others, and even trial and error when learning the layout of a region. On-going assistive technology research has yielded a number of promising techniques to help people who have visual impairments plan daily walks and get directions, but little has been done to promote the same kind of spatial awareness provided by visual maps. The Blind Audio Tactile Mapping System (BATS) project focuses on the latter area of research by helping people without sight access and explore spatial information.
