Audio phonebook for the blind people

The technology can in many ways help visually impaired people, but problem of memorizing a large number of phone numbers for most of blind people is still not resolved. The aim of this study was to design, construct and test a device that would serve as a phone book for landline phones. The device is connected between the phone and the phone line and therefore can serve as a memory for phone numbers. It is important that it has a very simple interface and allows unobstructed use of the phone. The device was tested by visually impaired people and feedback showed that it could be used without any problem and without special training.
