A wireless tactile communication device for the blind using finger braille –

Tactile information transfer is a mapping problem. To simulate this mapping, we have developed a glove embedded with accelerometers, magnetometers, and a controller. When the glove operator taps Braille codes using his/her fingers, the controller maps them to ASCII codes. Conversely, when ASCII codes are sent to the operator, the controller maps them to finger-vibration-Braille codes. – Link
