1. The Vice-Chancellor’s Cup of Student Innovation 2005 UI/06 Augmented Reality Table for Interactive Card Games Supervisor: Prof Michael Lyu Presented by: Kevin Chow, Albert Lam

2. Introduction What is Augmented Reality? What is Augmented Reality? Mixed Reality combines the content from the real world with virtual imaginaryMixed Reality combines the content from the real world with virtual imaginary Augmented Reality is a subset of this where virtual content is overlaid into real objects of the worldAugmented Reality is a subset of this where virtual content is overlaid into real objects of the world

3. Introduction An AR system has the following three main characteristics: An AR system has the following three main characteristics: Combines real and virtual objects in a real environmentCombines real and virtual objects in a real environment Runs interactively, and in real timeRuns interactively, and in real time Registers virtual objects onto the real worldRegisters virtual objects onto the real world

4. Introduction ART stands for Augmented Reality Table ART stands for Augmented Reality Table User can play Card Games on the ART.User can play Card Games on the ART. ART can enhance the visual effect during the playing of the card game.ART can enhance the visual effect during the playing of the card game.

5. Traditional Card Game vs Computer Card Game Traditional Card Game Traditional Card Game Interact with reason personInteract with reason person lack of sound and visual effectlack of sound and visual effect Computer Card Game Computer Card Game 3D Animation3D Animation Interact with computer onlyInteract with computer only

6. New Playing Style No product currently combine the two card game playing style except our ART system No product currently combine the two card game playing style except our ART system
