Spatial information is necessary to solve such problems. Maps are effective means used to store and communicate spatial information, and tactile direction maps are maps designed for supporting way-finding activities.Audio tactile technology emerged that aimed to reduce the burden onthe sighted guide and provide a more interactive experience to the learner. Audio tactile technology in volvesa touchpad connected to a computer.The tactile direction maps is placed on the touchpad and relevant audio feedback is provided to the blind people when they press on different areas of the tactile. The purpose of this study was to help visual impaired to access and explore spatial information by establishing a cognitive map of public place using IVEO hands-on learning system and tactile direction map. The IVEO hands-on learning system combines touch, sound, and sight, using touch and sound learning modalities to help the blind and visually impaired to learn faster and retain information longer, meanwhile making learning more interesting and interactive. Subjects were divided into four groups in terms of route familiarity and IVEO Aids of exposure, with an equal number of subjects (N=4) in each group. Then, the subject performed an actual Way-finding test to get back and forth between Ximending and TDTB (Taiwan Digital Talking Books 3 association). The dependent variables were total time, number of miss route, and number of request. The results revealed a significant effect of IVEO Aids, and the subjects could perform better through IVEO Aids. This research provided a learning method of orientation and mobility for the blind and visually impaired, and assisted them to be familiar with the route safer and faster.
