The IU Neuroscience Center has developed a new form of art therapy that uses technology to assist ALS patients. Amyotrophic lateral sclerosis (ALS) is a condition that gradually takes control over one's muscles and ultimately locks a person in their body. This makes it impossible for them to communicate with their loved ones, as well as share their inner experience with the world. Some people can still control their breathing and others are able to control their eye movements. In the later stages, many patients are unable to control their breathing. Technology can be used creatively to uncover even subtle changes in a person's biology and transform them into art or expression. Greg Hull (Dean of Indiana University Indianapolis' Herron School of Art and Design) and Juliet King (art therapist and former director of Herron’s art therapy program), developed the project in collaboration with Dr. Robert Pascuzzi, neurologist, and Juliet King. Hull combined his technological knowledge and microprocessors to produce expressive imagery. He used physiological data from patients to translate it into digital images. The videos are then transformed by subtle changes to the patient's physiology. These tools allow these patients to express themselves using their breathing, eye movements, and physiological data. The digital artwork is then projected on the walls of their rooms.
