Abstract: | Camera techniques are typically used in the study of human movement. However, as the number of joints and markers involved
in a study increases, data extraction and calculation become increasingly tedious and complicated. To overcome this challenge,
we propose a method of study that simplifies data extraction and calculation by using an electrogoniometer and dual Euler
angles. The contribution of the rotation of each arm segment to produce a racket head’s speed was identified in the context
of a badminton smash. The contribution of each segment rotation was computed using dual velocity analysis. A set of orthogonal
Cartesian frames was established for computing the anatomical rotational velocities for each of the three segments of the
upper arm. Electrogoniometers were attached to the subjects during the execution of the smash to obtain measurements of joint
angles throughout the motion. To test the algorithm, the calculated velocity of the racket head was compared to the measured
velocity. The calculated velocity was derived from an algorithm, while the measured velocity was obtained from a video image.
The results are similar, indicating that the dual velocity method is suitable for determining segmental velocities in such
kinematic situations. |
