These interactive maps for the blind are touch-sensitive and use audio instructions to direct the visually impaired around campus. Touch Graphics and the University of Buffalo's Center for Inclusive Design and Environmental Access developed the 3D printed mapping solution. Installed at a number of institutions across the United States, the most recent is the Talking Campus model at Perkins School for the Blind.
Both seeing and non-seeing visitors can use the multi-sensory maps for the blind. In addition to a touch-sensitive 3D surface and audio feedback, the Blind Talking Campus model also features an overhead video projector that floods the monochromatic surface with light to bring the map to life visually.
IDEA Center researcher Heamchand Subryan foresees the technology being incorporated into malls, museums and other academic institutions.
