A History of Assistive Vision

  • Series
Black and white photographic portrait of a close-up of a man's face. He is holding up a smartphone close to his eyes such that it obscures his nose and mouth. His eyes are directed towards the phone's screen. His finders are visible holding the phone on either side and the camera lenses of the phone appear in the bottom right corner of the image. The man's face and hands are spotlit in a small circle of light. He is standing against a black background which means he is surrounded by darkness.

He asks why Braille took so long to become popular, how the simple white cane has been hard to improve on, what people might be able to see that machines never will, and who is responsible for the parlous state of audio description in the UK’s cinemas.
