  1. An Application of Mixed Reality -- Camera “Pong” Game Name: Wang Jian ID: 0501794

  2. An Application of Mixed Reality -- Camera “Pong” Game Some Key Word • Virtual Reality • Mixed Reality • “Pong” • Camera “Pong”

  3. An Application of Mixed Reality -- Camera “Pong” Game Virtual Reality Virtual reality is a high-end user-computer interface that involves real-time simulation and interactions through multiple sensorial channels. These sensorial modalities are visual, auditory, tactile, smell and taste. (Grigore C. Burdea, Philippe Coiffet, 2003) Mixed Reality Mixed reality is a particular subset of virtual reality related technologies that involve the merging of real and virtual worlds somewhere along the "Virtuality continuum", which connects completely real environments to completely virtual ones (Milgram, 1994).

  4. An Application of Mixed Reality -- Camera “Pong” Game “Pong” “Pong” is a basic simulation of the racket sport of table tennis. A small square representing a ping pong ball travels across the screen in a linear trajectory. If the square strikes the perimeter of the playing field, or one of the simulated paddles, the square ricochets based on the angle of the impact. Game play consists of players moving their respective paddles vertically to defend their scoring zones. Players score one point by maneuvering the square past their opponent's paddle.

  5. An Application of Mixed Reality -- Camera “Pong” Game Camera “Pong” Camera “Pong” is just as its name implies – a “Pong” game but played with a camera. A simple “Pong” game sees a ball rebound on a screen, with nothing at its bottom except for a small board which is controlled by the player. It is possible to move this board flatly but if you are unable to rebound back the ball when it comes to the bottom of the screen, the game is over. But Camera “Pong” is a bit different as it changes the position of the board so that it is on the same level as the player’s head.

  6. An Application of Mixed Reality -- Camera “Pong” Game is the game designed for? Who • Who is disabled that can not play game using their hands Out of 2,100,429 people living in Shan Xi province, China, 93,049 of them have a disability. 49,569 people have a disability involving the use of their arm. This means that almost 2.4% people cannot use a mouse, a keyboard or a game joystick as normally as everybody else. Unfortunately, it is also the case then that more than 99% of computer games we use today have to played with a joystick. Therefore, for an entire 2.4% of the population of this region it is almost impossible for them to find any computer game that they can play. (Data source: Shan Xi Province partial areas disabled person sample investigation report.) • Who want relax their back or neck after a heave work in front of screen Experts have considered that computers have had too many bad effects on people, effects which computer users do not consider seriously enough. According to a number of investigations, 83% of people who used computers frequently felt eye strain, 63.9% of people felt back, neck and arm strain. Others suffered from headaches and a lack of appetite and these people account for 56.1% and 54.4% respectively. Over-exposure to computers is also alleged to cause depression, arteriosclerosis etc. If you do one exercise such as turning your neck or moving your back a few times every hour – as you sit in front of a computer - then 70% of those symptoms will be alleviated.(Data source: magazine “Computer and health”) • Who is sick to always work with computer using keyboard or mouse By December 31, 2005, China had a total of 111 million internet users and the average length of time these users spent on the Internet was 15.9 hours per week. That means that these people normally use the Internet for roughly 2 hours a day. This data is limited only to those people who use the Internet regularly; if you were to include those people who use the computer regularly but not for Internet-use the average length of time that they spent at their computers would be much more than the figures cited above. Virtually every movement of the computer involves the use of the keyboard or the mouse. (Data source17th Statistical Survey Report on the Internet Development in China ) • Who can not use mouse skillfully and who want try some new games

  7. An Application of Mixed Reality -- Camera “Pong” Game How to construct Camera “Pong”?

  8. An Application of Mixed Reality -- Camera “Pong” Game First step:Make sure what kind of game it is and the equipments we need for it. How will I make Camera “Pong”

  9. An Application of Mixed Reality -- Camera “Pong” Game Second Step: Establish playing rules for the game. 1. Computer will draw the outline of your head and compute its area/size automatically. If the computer does not see any head in the camera shot, the game will not start. 2. "Pang" rebounds on a screen when it hits both the rim of the video camera and the outline of the player’s head. 3. If the head area is greater than 1/5 of the whole video camera area or if half of the head leaves the area of the camera shot, then the game pauses. The head area will affect the score you get. 4. The semi-diameter of the “Pang” or the game’s speed can be changed as you wish by increasing or decreasing game level. Any change of these two will affect the score you get. 5. Support single player. 6. The rebound of “Pang” will according as physics. How will I make Camera “Pong”

  10. angle of incidence tangent angle of reflection Head outline

  11. An Application of Mixed Reality -- Camera “Pong” Game Third step:Make a Schedule for this activity This work will take 2 weeks as a stage, totally 5 stages. The schedule as below: 22/5/06 – 5/6/06 Establish a simple “Pang” game with director. 6/6/06 – 19/6/06 Improve the head identify system then try to combine these two parts together. 20/6/06 – 3/7/06 Debug this game and add a control function for the “Pong” and an area computation function for head outline. 4/7/06 – 17/7/06 Build a scoring system as relating to a different “Pong” size and differing head area. 18/7/06 – 31/7/06 Complete this game and do some preparation working for the final thesis. 1/8/06 -- Writing work. How will I make Camera “Pong”

  12. An Application of Mixed Reality -- Camera “Pong” Game Some technical problems • Definable problems • Graphic delay • Single software use cannot achieve the best function • The mixed reality technology is too advanced to come cross the threshold. • Problems not yet Evident

  13. An Application of Mixed Reality -- Camera “Pong” Game The EndThanks for attention!
