Contrasting Analysis Between Motion Capture Technologies

This research has explored capturing the motion of the human arm, and after a series of approaches, the two, most vigorous methods have been proven to be these two: A motion capturing method using the video camera known as the Microsoft Kinect, that was initially developed for use in the role of a game controller. The second motion capture method does not involve video, but a group of rotary linear potentiometers, known for their major performance in the domain of robotics. In the video-based motion capture, the interpretation of the arm's joints and elements, with their movements on the three spatial axis is done in software, with the help of the MATLAB environment, while the potentiometer-based motion capture, the angles are measured by the potentiometers themselves, the data being sent from the potentiometers to a computer's serial monitor through an Arduino development board. In all motion capture cases, the arm from which the motion is captured, has a well-established set of movements and trajectories. For the potentiometer-based motion capture, the arm is wearing an exoskeleton type of device, designed specifically for the task of motion capture, which includes the rotary potentiometers, for each joint and its possible motions, so that the shoulder has three potentiometers, the elbow has one, and the wrist has another one that measures the rotation of the forearm on the three spatial axes.
