Satnav will guide blind; TECHNOLOGY.
Monty Lilburn, 33, created the mapping software Loadstone, which uses GPS co-ordinates of bus stops, cashpoints and train stations.
The system can be downloaded free and has been praised by phone giant Nokia.
People with sight problems who use it will carry a small GPS transmitter and get instructions from their phone.
Mr Lilburn, from Glasgow, said yesterday: "When you're in a taxi, for example, you can be confident you're being taken on the shortest route."
