The research of the Economics of Movement group shows that movement and movement learning are similar in many respects. Our Sensors (Eyes, Ears, Skin etc) are not perfect but are noisy. Moreover, our muscles are noisy and if we try to do the same movement over and over it will be different each time. This means that if we make a movement, say swing a golf club, we will have uncertainty in the potential movement outcomes.

Our Sensors (Eyes, Ears, Skin etc) are not perfect but are noisy. Moreover, our muscles are noisy and if we try to do the same movement over and over it will be different each time. This means that if we make a movement, say swing a golf club, we will have uncertainty in the potential movement outcomes. Our group studies how people make movement decisions in the presence of such uncertainty. Our research has three main thrusts. (1)We study experimentally how people move and how their movements are affected by uncertainty. (2) We build computational models using Bayesian statistics to calculate how people could move optimally or learn to move optimally. (3) We build Bayesian Algorithms to solve problems that we find interesting. For example we analyze how neurons are connected in the nervous system. (4) We use mobile phone and gaming technology to improve rehabilitation and to improve diagnoses.

The main thrust of our current research is to allow for better rehabilitation procedures through an understanding of motor learning.[Shorten text]
