University of Florida researchers are developing a navigational aid for the blind and partially sighted which can steer users around obstacles and guide them to their destination.
The system comprises a waist-worn computer the size of an egg box, speech recognition software, a mobile phone and a headset, and is connected remotely to a map database server using satellite positioning technology.
The user enters their location and where they want to go, and the system responds with directions based on the user's starting point.
If the person veers off the pavement, travels too far, or strays into the path of a hazard, the system provides verbal corrections and warnings.
The researchers hope to develop the system into a commercial product in the next two years.
