From Screen to Braille

For a blind or visually impaired computer user, the Braille display replaces the computer video monitor and mouse. Text is converted into a tactile alphabet (Braille), on a row of 44 Braille cells. The information presented in the cells is refreshed in order to display another portion of the screen. The unique Satellite key concept enables the user to issue reading, navigation and related commands directly from the ALVA Satellite 544 Traveller. Productivity is increased by minimizing hand movement between the Braille display and computer keyboard.

Universal Compatibility
The ALVA 544 Satellite Traveller braille display can be readily integrated with most popular operating systems, hardware platforms, graphical screen readers, and speech synthesizers. The ergonomic design of the operating keys, buttons and switches are optimized for use in a variety of computing environments. USB and serial connections enable versatile and high-speed connectivity to the host computer.

Enhanced ergonomic design
The philosophy behind the ALVA Satellite 544 Traveller’s enhanced ergonomic design stems from the desire to have as much computer functionality directly from the Braille display as possible. Every key, button and Braille cells are smoothly coated and elegantly provide tactile feedback when pressed or toggled. The ALVA 544 Satellite Traveller is easy to transport and easy to use anywhere.
