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.
