A mobile computer that reads wireless transmitters, allowing blind people to navigate a city, could serve seeing pedestrians as well, students at the University of Michigan at Ann Arbor say.
The students have developed Talking Points, an urban-orientation system, to give users context about their surroundings.
“If it caught on, this would be an effective way to tag the whole world,” Jason Stewart, a master’s student at Ann Arbor, said in a written statement. “Anyone with a reader could use it to find out more information about where they are.”
The system’s mobile computers, about the size of paperback books, read Bluetooth tags — on city landmarks and other points of interest — and convey information visually or aloud. Members of the Talking Points community can edit that information, which is stored in an online database.
The project is similar to others — including one at Carnegie Mellon University — but Michigan says its use of Bluetooth, voice-command software, and user-generated content sets Talking Points apart. —Sara Lipka
