Adaptation of a cash dispenser to the needs of blind and visually impaired people

An existing cash dispenser was implemented with speech output to give access to blind and visually impaired people. Additionally, the screen graphics and the function access were modified. The hardware was not changed. Blind and visually impaired subjects performed a usability-test, and experts in the field of human-computer-interaction evaluated the dispenser system?s usability heuristically. The results showed that the modifications help blind and visually impaired people to access such machines, but adaptations of the hardware are necessary to maintain usability. The two evaluation methods did not produce consistent results.
