ABSTRACT
Motion capture has been used to analyze various aspects of human motion. There are two basic approaches to analyze motion, two dimensional and three dimensional. These approaches are often supplemented with the use of computer packages in order to handle complex calculations. The research performed attempted to determine whether a modest, portable motion analysis tool can provide results comparable to those obtained using 3D motion capturing system (Vicon) during a simple motion. The 2D software under investigation is called Dartfish which uses digital video as input and is able to generate values for the location of markers in two dimensions. It was found that the magnitudes of the differences in the markers' trajectories between Dartfish and Vicon were about ±5 mm. Based on the statistical analysis, it was concluded that this 2D method has serious potential for future studies that involves more complex movements.
