Calibration Methods for Effective Fish Tank VR in Multi-screen Displays.

We present cubic and spherical multi-screen fish tank virtual reality displays that use novel interactive and automatic calibration techniques to achieve convincing 3D effects. The two displays contrast the challenges and benefits of multiple projectors or flat-panel screens, borders or borderless, and the performance of headtrackers. Individuals will be able to subjectively evaluate the visual fidelity of the displays by comparing physical objects to their virtual counterparts, comparing the two displays, and by changing the level of calibration accuracy. They will be able to test the first markerless, interactive, and user-dependent headtracker calibration that promises accurate viewpoint registration without the need for manual measurements. In conjunction with an automatic screen calibration technique, the displays will offer a unique and convincing 3D experience.
