Visual Touch Therapy's creator Eric Medine has told Engadget that he hopes his platform will become the "Candy Crush" of physical therapy. Medine's system uses a video game, computer, and Leap Motion controller to provide a way for physical therapists to help their patients and track progress.
Using the Leap, patients control either a dog or jetpack with relatively simple motions. However, their ability to perform the correct motions and move the on-screen items allows physical therapists to see improvement in certain areas. Of course, Candy Crush is sort of an odd comparison, but we understand Medine's point.
Visual Touch Therapy costs just $25 per patient, so it is a relatively affordable system that could be integrated into physical therapy.
