electronics design
Modern TV programmes have disability access for the blind, including audio description. The program guide however still requires menu navigation using a remote control. Circad were asked to develop the electronics design for a product that would retail for under £100 to allow the Electronic Program Guide on SKY to be used by a blind person. 
We created Speaking Sky, a product that connected between a standard Television set and the SKY box. 
Working in real time it decoded infrared signals from the Sky remote control, then captured screen shots from Sky TV into a microprocessor. The screenshots were analysed using optical character recognition, and announced through the TV's own audio by a text to speech processor.
