AI summary

A system for music, physical therapy and rehabilitation has been developed that allows for differently-abled users of many types to create and perform music by use of their bodies, in ways found to be physiologically therapeutic. Many use cases including rehabilitation, physical therapies of various types, music therapies of different types and especially the combination of music and physical therapies are made possible by the system which uses a set of human-computer-interaction devices for input, such as eye trackers, motion trackers, IMUs and so on as input devices to a computer system outfitted with a number of software applications. The software applications in turn control outputs including music production systems as well as lighting and in some cases physical instruments, and the user can choose from a wealth of options to create a self-guided program of improvement.
