The device looks like a small camera attached to the side of a pair of glasses.
Using OCR – optical character reading – technology, the camera and tiny computer it contains can read printed materials.
Researchers at the University of California said the new system dramatically improves the ability of people with limited sight to read books, menus, newspapers and emails.
The camera is not limited to text: its makers said it can also recognise faces and products.
The research paper ‘Evaluation of a Portable Artificial Vision Device among Patients with Low Vision’ has been published in the US journal JAMA Ophthalmology. Source
