The Vice-Chancellors Cup of Student Innovation
2005UI/06Augmented Reality Table for
Interactive Card Games

• Supervisor Prof Michael Lyu
• Presented by Kevin Chow, Albert Lam

Introduction

• What is Augmented Reality?
• Mixed 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 world

3
Introduction

• An AR system has the following three main
  characteristics
• Combines real and virtual objects in a real
  environment
• Runs interactively, and in real time
• Registers virtual objects onto the real world

4
Introduction

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

5
Traditional Card Gamevs Computer Card Game

• Traditional Card Game
• Interact with reason person
• lack of sound and visual effect
• Computer Card Game
• 3D Animation
• Interact with computer only

6
New Playing Style

• No product currently combine the two card game
  playing style except our ART system

7
Objective

• Develop a generic Interactive ART Trading Card
  Game application.
• Enhance the traditional card games
• Visual effect
• Sound effect
• Complex calculation

8
Trading Card Game

• Trading Card Games
• Two players play a match.
• Players play cards to fight with each other. It
  includes summoning monster, casting magic, or
  setting traps, etc.
• We choose YU-GI-OHas our implementation

Architecture

• Hardware Setup
• Plasma monitor
• Overhead camera

Image Processing
Binary image difference
Image difference
Edge detection
Contour detection

Image Recognition

• Are they the same?

?
15
Image Recognition

• Select the best matched card from the candidates
  
• Split the captured image into 4 channels
• Compare only inner image
• Compare the different channels to the database
  separately
• Find the pixel difference

16
Rulebase

• Rulebase as game engine to maintain game logic
• e.g.

17
Database

• Contains all game information
• Image Database
• Contain all card image
• Card Database
• Contain all card information
• Rule Database
• Contain all game rule and card rule

Practical Application Value

• Image Database
• Support query an image from low resolution
  distorted image
• Virtual Button
• Use monitor and camera to function as a touch
  screen device
• Much cheaper than buying a touch screen monitor

20
Market opportunity

• Provide a generic prototype for most card games
• Attractive to producers of trading card game
• AR game playing style interests arcade game
  manufacturer

21
Summary

• We have designed and implemented the prototype of
  ART system
• We have developed a rule-based game engine which
  is generic and extensible for card games
