Our system consists in tracking a portable artifact based on color evalua· tion by computer vision, and use it as a 3D input device. Using vision-based techniques, we are able to detect and track the motion of a physical object through color analysis and segmentation, and then perform virtual interactivity to the user, which is extremely important in a Tangible Augmented Reality approach.Augmented Reality (AR)Mixed Reality (MR)Tangible Interface6DOFCalor SegmentationCamera CalibrationMotion Prediction10.2312/pt.2004150199-108
