摘要
In this paper, we describe an augmented reality tool for collaborative work called the MagicBoard. The MagicBoard is based on an ordinary white board which has been enhanced by a video-projector and a steerable camera. A supervisor coordinates the cooperation of several modules including gesture recognition, finger tracking and white board scanning for digitalisation of the content. The gesture recognition module uses an approach based on local spatio-temporal appearance of activities. The tracking module is designed for use with cluttered backgrounds and variable lighting conditions. The white board scanner eliminates global luminosity differences by adaptive thresholding and the result can serve to digitise the content of the board. The supervisor is based on a rule-based architecture and is easily extendable. The selected modules fit together to a compact system, that largely increases the functionality of a white board and makes it a useful tool in the future office environments.
