Abstract: Immersive exergames at home have become popular due to the advance in gaming headsets. A typical commercial gaming headset contains a head-mounted display (HMD) and a pair of hand-held controllers for interacting with virtual objects. Given this setup, an additional motion capture camera will be needed to allow full-body motion tracking. However, using the motion capture system within the immersive virtual environment (IVE) at home could be challenging since proper setup and calibration are required for a specific home environment. Hence, to simplify the camera setup and calibration issue, this work introduces the design of the calibration module for a motion capture system using the Azure Kinect camera. The calibration module allows the user to perform calibration and self-evaluate the camera setup in the immersive virtual environment. Once it has been calibrated, users can drive a full-body avatar through their body movements in the first-person perspective.
