Braillex: First Refreshable Braille Display
In 1975, Papenmeier Reha Technology produced the first commercial refreshable braille display, the Braillex. Research on the Braillex began several years earlier in a program with Prof. Dr. Werner Boldt of Dortmund University. The original Braillex used a cassette tape for memory storage, and allowed users to input information using braille input, and read stored information on a braille display. According to Papenmeier’s history page (which includes a picture of the original Braillex), users found it easy to use and reported the information retrieval was fast.
