Viper Vision

Vipers “see” by sensing the infrared radiation emitted by the heat of their prey using sensitive organs on their head. Inventor John Stapleton of New Jersey, US, thinks same trick could enable the visually impaired to better sense the world around them.  Stapleton’s device uses an ordinary digital camera light sensor to capture a scene which it converts into a mosaic of light spots. An array of infrared LEDs then transforms this mosaic into a pattern of heat points which can be projected onto a user’s forehead.
