The ZEN or “Z-axis Enabled” computer is comprised of “an electronic surface that can take different physical shape and can be manipulated by the user.” It lets you “read Braille text on it, make out windows, icons, and different textures.” No word yet on availability.

You can press into the surface, or scratch it with your fingers. All input output is made with the sense of touch. ZEN software uses a Tactile User Interface (TUI). The visually impaired are a negated market.
