What are the latest technology aids for the visually impaired ?

technological advances in OCR (Optical Charecter Recognition) and Speech synthesizers can greatly help the visually impaired. Can it replace Braille ? can the visually impaired have access to all the reading material others have? Do they still need the support of a scribe to appear for an examination?
