Pixels guide the way for the visually impaired

Images have been transformed into pixels and projected onto a headset to help the visually impaired in everyday tasks such as navigation, route-planning and object finding. Developed using a video camera and mathematical algorithm, the researchers from the University of Southern California hope the pixels can provide more information and enhance the vision of patients already fitted with retinal implants.
Lead author of the paper, James Weiland, said: "Blind people with retinal implants can detect motion and large objects and haveimproved orientation when walking. In most cases, they can also read large letters."
"At the moment, retinal implants are still low-resolution. We believe that our algorithm will enhance retinal implants by providing the user with more information when they are looking for a specific item."
