Tactile Mapping for Visually Impaired Children

Dr. Regina Vasconcellos Department of Geography/University of Sao Paulo C.P.8105 Sao Paulo SP Brazil 05508-900 Fax: 55118183159 E-mail: [email protected] The paper presents the results of five years of research on tactile mapping for visually impaired children carried out at the University of Sao Paulo, Brazil. Based upon empirical research, the author has developed a model for tactual cartograph...

Mapping the internal geometry of tactile space.

A large body of research has shown spatial distortions in the perception of tactile distances on the skin. For example, perceived tactile distance is increased on sensitive compared to less sensitive skin regions, and larger for stimuli oriented along the medio-lateral axis than the proximo-distal axis of the limbs. In this study we aimed to investigate the spatial coherence of these distortion...

BATS: The Blind Audio Tactile Mapping System

The BATS project focuses on helping students with visual impairments access and explore spatial information using standard computer hardware and open source software. Our work is largely based on prior techniques used in presenting maps to the blind such as text-to-speech synthesis, auditory icons, and tactile feedback. We add spatial sound to position auditory icons and speech callouts in thre...
