Upper body tracking using the Polhemus Fastrak
Scott McMillian · Calhoun: The Naval Postgraduate School Institutional Archive (Naval Postgraduate School) · 1996
This technical report presents the design and implementation of the sensor system used to track the arms and rifie motions with respect to the upper body. This was performed as part of the AUSA '95 dismounted infantry vvork - an effort to insert humans into NPSNet's distributed virtual environment. The sensor work can be divided into three areas: (1) the Fastrak setup including sensor positions and interface to the computer as well as the device driver software, (2) the software interface to the Jack model and the inverse kinematics algorithm needed to achieve "reasonable'' arm tracking, and (3) the implementation of the rifie tracking and the initial at.tempts at targeting.
