Pages of interest: Motor Control, Motion capture, Kinematics, Microsoft Kinect, Accelerometer

Reaching kinematics provide insight to how people adapt to visual information during the performance of visuomotor tasks. To understand how people control their arm reaching kinematics, researchers have been using various motion capture systems. Commonly, researchers are using the optical motion capture system with passive reflective markers. This system allows us to monitor the 3-dimensional position of human body with high resolution. In recently, emerging computer vision technology allows us to develop markerless optical motion capture system. Along with these optical systems, researchers have also been using inertial sensors and/or magnetic sensors to research human reaching kinematics. The inertial motion capture systems including gyroscopes and accelerometers can record the rotation and acceleration of the subject. Magnetic motion capture system using Anisotropic Magneto Resistive (AMR) sensors can capture the position and orientation of the object by quantifying magnetic field electronically . Each of these motion capture systems captures the human arm reaching kinematics differently, and these have pros and cons respectively. So researchers have been trying to combine different types of motion capture systems to record the human arm reaching movement, and it can help us to capture the human reaching movement kinematics accurately. Also, by using the low cost motion capture systems, such as Microsoft Kinect, we can develop the home-based motion monitor system for evaluating older adults' movement quality, and home-based rehabilitation tools for individuals with movement disorder.

Assignment 1: Bokkyu Kim — Background, research interests, and goals for the course

I am a licensed physical therapist in South Korea. I graduated from Korea University Dept. of Physical Therapy which is the best Physical Therapy program in South Korea. As a physical therapist, I have three-year clinical experiences in neurologic physical therapy area in South Korea. Also, I was conferred a Master of Science degree in Rehabilitation Science by Korea University. My research during the master's course was identifying the mechanism underlying functional recovery after spinal cord injury with animal models. My current research interest is more pragmatic than my works during the master's program. My research interest is understanding mechanism underlying motor learning of individuals after stroke, and developing novel therapeutic approaches for people with neurologic disorder based on the motor learning mechanism to ameliorate their physical function. The goals for this course is to improve my scientific writing skills, and to learn about how I can communicate effectively with other people about my research.
