Braille keyboard uses MEMS technology From: Electronic Design - October 21, 2002 - page 164 A Braille keyboard display system implements refreshable micro-actuated keys that communicate with the computer. A "miracle worker" is coming for the blind thanks to micro-electromechanical systems (MEMS) technology, in the form of a Braille keyboard display system that allows the blind to access information via computer. The keyboard's keys are formed from Braille characters that react to computer signals by popping in and out, so the blind person can "read" what's on the computer screen. Relying on MEMS microvalves, these upcoming systems would dramatically lower the cost of today's keyboard-like Braille display systems. Orbital Research Inc.'s team is involved in developing microvalves for a Refreshable Braille Display System (RBDS). RBDS will allow blind people to access internet and other electronic communications at a much faster rate. Development of a Refreshable Braille Display System This project will design, fabricate, and test a multi line Refreshable Braille Display System (RBDS) that utilizes MEMS microvalves. The close proximity of Braille dots and between Braille characters create a complex network of wires and actuators that limit the number of Braille characters and increases the size of current Braille displays. Improved actuation mechanisms are required to provide more Braille characters that would emulate a sheet of Braille text and/or the computer monitor. Any new devices must require the proper vertical deployment of the Braille dots, spacing between dots, low power, fit into tight spaces, and provide rapid (real-time) response, all while being affordable. In Phase I, Orbital Research demonstrated the feasibility of most of the necessary components of the RBDS including a MEMS microvalve. This multi-line display will be composed of Braille modules with a fixed number of Braille characters that can be integrated into larger Braille display. The display would produce computer based information either from the hard drive, CDROM, or the Internet in literary Braille, computer or math code using commercially available software. Thus, this device would more effectively enhance educational and research opportunities for visually impaired and also visually and hearing impaired individuals.
