Light Detector is a light detection program designed for use by individuals who are blind or have low vision. This application (or app) allows a person to use their Apple iPhone, iPod Touch or iPad to detect light sources. Light Detector transforms natural or artificial light sources it encounters into sounds. The user launches the app, points the device’s camera towards a direction, and the app will produce a higher or lower sound depending on the intensity of the light. Light Detector can be used at home to check whether the lights are on or off, to check locations of windows, and to check whether the shades are drawn by moving the device up and down. COMPATIBILTY: For use with the Apple iPhone, iPod Touch, or iPad. Each device must be equipped with a camera. SYSTEM REQUIREMENTS: Apple iOS 4.0 or later.
