Tactile Video Displays in the works

by

tactile-display.jpgThe National Institute of Standards and Technology has successfully developed active Braille-like technology that aims to bring a newfound sense of freedom and empowerment to blind folk, letting them “feel” images just like how the rest of us sighted folk see on a video screen. This technology has already been licensed to a commercial firm in order for it to be manufactured into actual products that could be purchased off the shelf by ordinary folk. Sounds pretty interesting, eh – read on for more after the jump.

ELIA Life Technology Inc. of New York, N.Y., licensed for commercialization both the tactile graphic display device and fingertip graphic reader developed by NIST researchers. The former, first introduced as a prototype in 2002, allows a person to feel a succession of images on a reusable surface by raising some 3,600 small pins (actuator points) into a pattern that can be locked in place, read by touch and then reset to display the next graphic in line. Each image-from scanned illustrations, Web pages, electronic books or other sources-is sent electronically to the reader where special software determines how to create a matching tactile display. (For more information, see “NIST ‘Pins’ Down Imaging System for the Blind”.)

An array of about 100 small, very closely spaced (1/10 of a millimeter apart) actuator points set against a user’s fingertip is the key to the more recently created “tactile graphic display for localized sensory stimulation.” To “view” a computer graphic with this technology, a blind or visually impaired person moves the device-tipped finger across a surface like a computer mouse to scan an image in computer memory. The computer sends a signal to the display device and moves the actuators against the skin to “translate” the pattern, replicating the sensation of the finger moving over the pattern being displayed. With further development, the technology could possibly be used to make fingertip tactile graphics practical for virtual reality systems or give a detailed sense of touch to robotic control (teleoperation) and space suit gloves.

I wonder how this would affect other industries for the sighted – I can just imagine folks surfing porn sites and implementing such technology in order to increase the level of “realism” of their content.
