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…
Crosswatch is a smartphone-based system developed for providing real-time guidance to blind and visually impaired travelers at traffic intersections. Using the smartphone's built-in camera and other sensors, Crosswatch is designed to tell blind and visually impaired travelers what kind of traffic intersection they are near, how to align themselves properly to the crosswalk, and when the walk light or other traffic light indicates it is time to cross.

The goal of the Display Reader project is to develop a computer vision system that runs on smartphones and tablets to enable blind and visually impaired persons to read appliance displays. Such displays are found on an increasing array of appliances such as microwave ovens, thermostats and home medical devices.
