    CamIO (short for “Camera Input-Output”) is a system to make physical objects (such as documents, maps, devices and 3D models) accessible to blind and visually impaired persons, by providing real-time audio feedback in response to the location on an object that the user is touching. CamIO currently works on iOS using the built-in camera and an inexpensive hand-held stylus, made out of materials such as 3D-printed plastic, paper or wood.

    See a short video demonstration of CamIO here , showing how the user can trigger audio labels by pointing a stylus at “hotspots” on a 3D map of a playground. See…
