Abstract :
The authors describe work toward the implementation of a tactile vision information system (TVIS). The prototype system consists of a video camera for image acquisition, a microcomputer for image processing, and a 16×16 vibro-tactile array for image transfer to the skin. The characteristics of the TVIS are discussed and proposed modifications are analyzed to determine the optimum configuration. The mechanical impedance of both vibrator and selected skin sites are discussed and related to the image-transfer process. This is combined with the published properties of the tactile sensors to determine the overall transfer function of electromechanical-physiological interface
