A Low-Cost Approach to Fish Tank Virtual Reality with Semi-Automatic Calibration Support

We describe the components and implementation of a cost-effective fish tank virtual reality system. It is based on commodity hardware and provides accurate view tracking combined with high resolution stereoscopic rendering. The system is calibrated very quickly in a semi-automatic step using computer vision. By avoiding the resolution disadvantages of current VR headsets, our prototype is suitable for a wide range of perceptual VR studies.
