Experiential systems, health and well-being

We are strongly motivated by the applications of our algorithmic innovations in the emerging area of interactive experiential systems: as diverse as real-time feedback for stroke and Parkinson’s rehab, to media-systems for general well-being, to next generation of interactive performative techniques. We collaborate widely with researchers in bio-mechanics, exercise science, physical therapy, and media-arts. In many of these application, our core approach is to model underlying dynamical processes relevant to the human activity of interest, and extract interpretable data streams which can be used to drive real-time feedback via sonification, haptification, and other diverse forms of sensorial feedback. Some of our sample work in this area is given below.
