Vanderbilt University. The college's Medical and Electromechanical Design Laboratory (MED Lab) is working on an Android app that turns tablets into a teaching aid for the visually impaired. Areas of math that rely heavily on visual elements, such as algebra and calculus, prove problematic for students with poor eyesight. A common solution involves pipe cleaners, a cork board and push pins, to recreate graphs, but the method is quite slow. The MED Lab is looking to haptic feedback as a way to help the visually impaired identify lines, graph points and other data that is normally represented visually.
