Researchers have developed two technologies wich could help the visually impaired “see” electronic images just like “reading” with Braille… Researchers Oliver Slattery and John Roberts use the tactile graphic display device to depict the NIST logo. Their new systems translate electronic images in to Braille—like patterns, enabling the visually impaired to “see” the images. Researchers John Roberts and Oliver Slattery of the National Institute of the Standard Technologies (NIST) Information Technology Laboratory have created tow tactile graphic displays that bring electronic images to the blind and visually impaired in the same way that Braille makes words readable. The inspiration for both tactile graphic displays came from a “bed of nails” toy. “watching the pins in the toy depress under fingers and then return to their original state got us thinking about how the principle could be applied to electronic signals,” said researcher John Robert. thanks, mukesh jain.
