Elizabeth Goldring, a blind specialist working at the Massachusetts Institute of Technology (MIT) in the United States, has designed a “seeing machine” that allows people with limited vision to see the faces of friends, images, and words.
This device—estimated by MIT to cost around $4,000 to produce—plugs into a personal computer and uses light-emitting diodes to project selected images onto the eyes of the user, enabling those with vision impairment to see words and images.
According to Goldring, the device fits neatly in a box that is 30.48 cm long and 15.24 cm wide. The device has been tested on 10 individuals with low vision, specifically those who cannot see anything smaller than the letter E on an eye chart, and most reported being able to see images and recognize simple words.
