This paper lists and describes several items of new technology, and shows how they can be used to assist blind and partially sighted people. One problem that blind and partially sighted people have is to know what facilities are available to them and how to access them. Visual signs can be supplemented by talking information systems and audio talking maps, to enable them to visit shopping centres, transport interchanges, universities, sports areas, and other places. Orientation devices for these people aim to give them information, which they can use to reach their destination from their starting point, while following a safe and sensible route. They include: (1) remotely triggered signs, which can read out information from public displays to which they are connected; (2) the REACT radio frequency beacon system, where the user carries a small device to trigger speech from a nearby beacon; (3) the Pathfinder infrared beacon system, whose user part transmits messages to users coming within range; (4) talking information systems; (5) audio tactile maps; and (6) global positioning satellite systems and talking maps. There are also devices that people can use to call help. Work is also being done on adaptations of automatic teller machines (ATMs) for use by people with various disabilities, and on communication devices.
