Textured Tactile Touchscreens

HizookRobotics writes "A new covering developed by Senseg and Toshiba Information Systems gives touchpads, LCDs, and other curved surfaces (eg. cellphones) programmable texture using a high-resolution electrotactile array — a grid of electrodes that excite nerves in the skin with small pulses of current to trick the body into perceiving texture, pressure, or pin-pricks depending on the current amplitude and electrode resolution. The new covering has many potential applications: interactive gaming, touchscreens with texture, robot interfaces, etc."
