Elizabeth Goldring smiles as she shows a visitor photos she's taken -- and can see - with her blind eye. The demonstration comes more than 20 years after Goldring, a senior fellow at MIT's Center for Advanced Visual Studies, and colleagues began work on a "seeing machine" that can allow some people who are blind or visually challenged to access the Internet, view the face of a friend and much more. The team has moved from Goldring's inspiration, a large diagnostic device costing some $100,000. (source: web.mit.edu)
