This paper reports the results of three experiments on tactile perception, spatial representation, and tactile display design for assistive mobility devices for blind, partially sighted, and deaf blind people. The results indicate the potentials of tactile displays for supporting environmental exploration and mobility. Voluntary test subjects showed reasonably good ability to determine the direction of motion of an arrow, with best recognition rates in the up and right directions. They showed reasonably good ability to use a tactile display to detect and avoid obstacles after a very short learning period and more limited ability to learn and remember an environmental representation using information from a tactile display and walking through the environment without specific instructions.
