RESUMO
The low cost, simple, robust, mobile, and easy to use Mobile Motion Capture (MiMiC) system is presented and the constraints which guided the design of MiMiC are discussed. The MiMiC Android application allows motion data to be captured from kinematic modules such as Shimmer 2r sensors over Bluetooth. MiMiC is cost effective and can be used for an entire day in a person's daily routine without being intrusive. MiMiC is a flexible motion capture system which can be used for many applications including fall detection, detection of fatigue in industry workers, and analysis of individuals' work patterns in various environments.

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.

Motion capture systems may be difficult to use in harsh environments such as a poultry plant, and therefore should be self-contained, portable, unobtrusive, and not interfere with or be degraded by plant machinery or processes. The purpose of this study was to evaluate the validity, reliability and accuracy of the ShapeTape system as a potential solution. This was accomplished by comparing kinematic data from the ShapeTape against the Vicon system. Subjects performed cyclical movements along a plane angled 45° up from the horizontal using their right arms. Results revealed that the ShapeTape kinematic data was significantly larger than the Vicon data, yet statistically reliable.
