According to RFID News, a UK-based charitable organization known as Guide Dogs is working with the University of Reading to employ RFID technology to provide the visually impared with the means to choose how they get about. The way-finding system consists of three main components: RFID tags, a handheld receiver, and a database of pre-recorded messages about each tag’s location.
The tags are embedded in the surrounding environment such as at bus stops or indoor shopping centers. When it comes into range, the handheld reader scans the tag and speaks to the user, telling exactly where he/she is. The system, dubbed Talking Tags can also provide additional information about the immediate environment around them. Users and potential service providers such as city officals, retail outlets, and transit providers recently tested the system in London and gave it positive reviews.
