Inertial measurement units (IMUs) are self-contained devices that measure kinematic information without emitting signals or requiring external references. Advances in MEMs technology combined with improved sensor fusion and estimation techniques have made IMUs the preferred sensing modality for a growing number of biomechanical applications. IMUs attached to the feet can provide measures of stride distances and variabilities during walking, with accuracy comparable to more expensive and less portable systems such as optical-based motion capture system and gait mats. We have proven that adding an additional sensor to the subject's torso provides enough information to generate high-quality reconstructions of more complex events such as losses-of-balance and falls. This talk will discuss a number of medical applications that utilize IMUs, including gait assessment, long-term monitoring, event reconstruction, and biofeedback.

Motion capturing beyond the laboratory

Lauro Ojeda, PhD

Research Scientist Mechanical Engineering, College of Engineering University of Michigan

Lauro Ojeda is a Research Scientist at the University of Michigan. He studied Electrical Engineering at the Army Polytechnic School in Quito-Ecuador. He has over 20 years of experience in the fields of inertial sensing, sensor data fusion, estimation techniques, Kalman filtering, biomechanics, and gait analysis. His work in these fields has been the basis of current unrestrictive gait analysis research, conducted in collaboration with several departments at the University of Michigan and other research centers across the world. He developed identification and reconstruction techniques capable of providing the first biomechanical measurements and reconstruction of loss of balance events as they occur in ordinary life.
