ME Graduate Seminar: 'A Dynamic Approach to Inertial Motion Capture'

Thursday, November 3 at 3:30 pm to 4:20 pm
2217 Seamans Center

Eric Frick, a PhD candidate in the Department of Biomedical Engineering at the University of Iowa, will present "A Dynamics Approach to Inertial Motion Capture." Abstract: Due to technological advances in recent decades, inertial motion capture (IMC) has presented itself as a viable alternative to the more traditional optical motion capture (OMC). IMC has many benefits over OMC, particularly its lower cost and ease of use, but it also suffers from several limitations, particularly its inability to directly measure position. The goal of most motion capture is to digitize motion via identification of the joint centers and associated joint angles. Most approaches to IMC do this by estimating orientation and propagating it through a biomechanical/kinematic model, similar to the OMC process. While useful, this approach tends to accumulate error, and ignores much of the information IMC offers. By approaching the motion capture problem from a dynamics perspective, previously unused relationships can be exploited to directly yield the joint centers, from which the joint angles can be calculated. This approach is far more direct, reducing the accumulation of error. Individuals with disabilities are encouraged to attend all University of Iowa sponsored events.
