Sailing by sound

Client: Lancelot Robson <Lancelot.Robson@metaswitch.com>

People with visual impairments enjoy outdoor activities as much as we all do, and local sailing organisations are pleased to provide opportunities for disabled and visually impaired people to experience sailing. One disappointing limitation is that the standard navigation instruments (location, windspeed, compass heading etc) all have visual readouts, so visually impaired people are not able to participate in this central aspect of sailing. Your task in this project is to create an embedded device (you will have technical assistance with hardware - bdj23@cam.ac.uk) that uses a Raspberry Pi to communicate with navigational instruments using the NMEA2K standard, and provides users with speech output in response to commands given via a small number of waterproof buttons on the outside of the unit.
