Motion Capture System Using Wiimote Motion Sensors

The purpose of this study is to examine the Wiimote MotionPlus system as a method to capture angular kinematic data of the knee, hip and back of a participant performing a lifting task. Twenty one subjects were recruited and asked to perform a lifting task while having four Wiimotes strapped to the lower leg, upper leg, and back at the hip and below the shoulder blades. The raw signals from the four Wiimotes were filtered and normalized before being combined to obtain the proper change in angular data. The results of the study demonstrate that it is feasible to combine the data from multiple Wiimotes to obtain kinematic data which may be used in ergonomic analysis.
