3D avatar developments in real time and accuracy assessments

This paper focuses on an application motion control of avatar and accuracy measurements using Kinect. The development of this application has used C++ Builder as a compiler and libraries to connect with Kinect and show 3D virtual world and avatars. OpenNI library is to detect a depth image while NITE Primesense library is to connect with Kinect, and Chai3D to display virtual worlds and avatar (human motion models). The tests to measure the application performance consist of 2D-3D angular measurements and time delay measurements on motions between avatar and a controller. The paired T-Test results on angular measurements showed that 2D and 3D angular measurements can be substitutable depended on the positions between Kinect and a controller. Furthermore, comparisons by ratio between the time difference showed varies due to the motion factors, the number of vertices and the distance between Kinect and the controller.
