Games and their use in rehabilitation have formed a new and rapidly growing area
of research. A critical hardware component of rehabilitation programs is the
input device that measures the patients' movements. After Microsoft released
Kinect, extensive research has been initiated on its applications as an input
device for rehabilitation. However, since most of the works in this area rely on
a qualitative determination of the joints' movements rather than an accurate
quantitative one, detailed analysis of patients' movements is hindered. The aim
of this article is to determine the accuracy of the Kinect's joint tracking. To
fulfill this task, a model of upper body was fabricated. The displacements of the
joint centers were estimated by Kinect at different positions and were then
compared with the actual ones from measurement. Moreover, the dependency of
Kinect's error on distance and joint type was measured and analyzed. IMPLICATIONS FOR REHABILITATION: It measures and reports the accuracy of a sensor that can be
directly used for monitoring physical therapy exercises. Using this sensor
facilitates remote rehabilitation.
