"A legally blind poet at the Massachusetts Institute of Technology has designed a "seeing machine" that allows people with limited vision to see faces of friends, read or study the layouts of buildings they intend to visit.
The device, which MIT estimates costs about $4,000 to manufacture, plugs into a personal computer and uses light-emitting diodes to project selected images into a person's eye, allowing visually impaired users to see words or pictures. "The advantage of this kind of display is there's no extraneous stuff in your peripheral vision that gets in the way," Elizabeth Goldring, who has published three volumes of poetry, said in an interview. "The image gets projected right onto the retina."
The device, which Goldring calls a "seeing machine," is housed in a box that measures about 12 inches by 6 inches by 6 inches."
