Talking Signs

An assistive technology system that uses infrared (IR) frequency modulated voice signals to transmit spoken information about signage to people with vision loss. Developed by the Smith-Kettlewell Eye Research Institute in 1992, Talking Signs broadcast recorded messages that can be received by a handheld or wearable receiver with a directional antenna, allowing users to scan their surroundings and listen to sign content from a distance. The system addresses the fundamental problem that people with severe vision loss cannot locate or read conventional signage, even tactile or Braille signs, without first finding them by touch.
