Dr. Habibi is an assistant professor in the Department of Integrated Engineering at the Minnesota State University-Mankato. He received his undergraduate and graduate degrees in Electrical Engineering. Following his postdoctoral appointments at the University of Wisconsin-Milwaukee, he joined the Iron Range Engineering (IRE) Program in August 2011. The IRE is an innovative, 100% project-based, upper division engineering program located in Virginia-Minnesota which promotes learning in the context of engineering projects, professionalism and reflection (metacognition). His research in the area of engineering education is focused on project-based learning, design and innovation, professionalism and self-directed learning.

Developing an integrated motion capture and video recording for pediatric biomechanical studiesA kinematic understanding of gait has numerous applications in biomechanics, such asdeveloping biometrics for gait pathologies and studying neuromuscular disorders. Motioncapture (mocap) and, video recording have been extensively used to study, evaluate and developeffective treatments for movement problems. Mocap provides valuable information that can notbe seen by eyes and significantly makes a difference in treatment methods.A commonly used method of mocap involves attaching reflective markers to a patient's joints,and then using an array of infrared cameras to record the movement of joints or muscles as a setof points. Mocap and video recording from multiple perspectives can be simultaneouslyperformed and synchronized by a controller.However, some problems such as high costs (up-front and maintenance), adhering markers ontodelicate skin of infants, high computer hardware requirements, and parental concern have beenreported. There is a need for a low-cost, markerless motion capturing, integrated with videorecording to address the problems associated with current mocap systems.Since the Microsoft Kinect is an array of sensors with motion capture capabilities, we selectedthe Kinect as the motion capture camera. Our solution involves using multiple Kinects to recordmotion data and a graphical user interface (GUI) that enables the user to interact with the system.The GUI also synchronizes multiple video clips and integrates them with the motion capturedata. Playback, frame-by-frame control of the video and motion data simultaneously, showingframe number in sections of interest during playback are some of the GUI features.This project is the result of collaboration between the Pediatric Neuromotor Laboratory at theUniversity of Wisconsin-Milwaukee and the Iron Range Engineering (IRE) program ofMinnesota State University-Mankato. The faculty mentored the student team and helped todevelop the idea. IRE students investigated the options and completed the project. This projectprovided both technical and professional learning for the students.The draft will consist of the following: An introduction to the application of motion capture/video recording in pediatric physical therapy Current issues associated with using the mocap technology on infants Project overview and methods Students’ technical and professional learning Results and discussion Conclusion and future work
