App turns Android tabs into math tools for the visually impaired (video)

Two high school students are taking part in a bit of an experiment at 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. For more details about the project check out the video after the break.
