Abstract

We designed and implemented a tangible game interface using projector-camera systems. The system offers a simple and quick setup and economic design. The projection onto a paper board held by the user provides more direct viewing as well as more natural and flexible interaction than bulky HMD's or monitor-based game interfaces. Homography calibration techniques are used to provide geometrically compensated projections on the board with robustness and accuracy.
