| Research Abstract |
We developed augmented desk system, named Enhanced Desk, which smoothly integrates paper and digital information on a desk. The system provides users an intelligent environment that automatically retrieves and displays digital information corresponding to the real objects (e.g. books) on the desk by using computer vision. The system also provides users direct manipulation of digital information by using their own hands and fingers for more natural and more intuitive interaction.
We developed a novel method for real-time finger tracking on Enhanced Desk by introducing a infrared camera, pattern matching with normalized correlation, a pan-tilt camera. We extended the method from 2-D to 3-D by using multiple cameras. In order to recognize objects on Enhanced Desk, we first used 2-D barcode. However, it is sometimes difficult to attach the barcode to some objects. In order to, solve this problem, we developed a new method for interactive object registration and registration by using color information of the objects. Then we discussed the use of head pose and position for human-interaction by using real-time face tracking system.
Finally, we developed some applications on Enhanced Desk. The first application is Interactive Textbook, which is aimed at providing an effective learning environment. The second application is the Interactive Venn Diagram, which is aimed at supporting effective information retrieval. The third application is Snap Link, which enable interactive object registration and recognition. The forth application is a two-handed drawing tool on Enhanced Desk
