Title:
Exploratory Data Analysis for Human Motion Data

Abstract:
This talk will discuss data that is collected by placing sensors on a subject's body as he walks a treadmill. In this case we will consider exploratory data analysis for the knee joint. Considering the upper and lower legs as rigid bodies, the motion of one relative to the other can be described by a path in the rotation group in three dimensions SO(3). Our approaches to exploratory data analysis will be deeply rooted the geometry of SO(3).

The talk will be highly preliminary in that it is based upon a few days of conversations between the speaker, Peter Kim of Univ. of Guelph Statistics, and Michael Pierrynowski of McMaster Univ. Rehabilitation Sciences. Any suggestions from the audience will be highly welcome.
