Abstract:	最近任天堂公司以及新力公司開發出了Wii以及Play Station 3，使用者可以利用手中感測器的按鈕或揮動感測器來控制遊戲畫面當中人物的一舉一動以及視野的改變，可以讓使用者感覺有趣好玩。本論文的目的為捨棄所有的感測器，單單只利用一台便宜的視訊攝影機來達到以上功能。本論文完成的主要目的有以下三大項： 1. 3D虛擬環境開發，用以和影像偵測結果互動。 2. 利用影像偵測與辨識技術抓取視訊畫面當中人臉的區塊，然後驅使所建立好的3D虛擬環境做出對應人臉移動的視野轉換，讓使用者感覺電腦螢幕上之3D視野是會隨著使用者頭部移動而有所改變，彷彿在看真實的物體一般。 3. 使用者手中抓取著一個簡單的有色光源(比如手電筒)，利用影像偵測技術抓取出光源的位置，並且判斷光源的移動方向，藉此移動電腦螢幕上之3D虛擬實境當中的物件。本論文最大的成就是不用藉由貴重的感測器，只要一台視訊攝影機就可以在電腦螢幕上完成和3D環境互動的效果。此技術成本低廉且不只是可以應用在遊戲上面，舉凡有使用到3D虛擬實境相關應用皆可以直接套用，而且不用另外特製的立體眼鏡或是面板。期許此技術推出之後可以達到拋磚引玉的效果，讓現有的3D技術可以更引人注目並引進更大的商機。 Recently, both Nintendo and Sony produce some fashionable 3D video game consoles such as Wii and Play Station 3. The 3D objects or 3D view could be controlled by pressing the buttons of the gamepad or by waving a remote control. It is much more fun when more interaction is added to the 3D environment. This thesis provides some methods which make the 3D environment have more interactive with users using only one webcam, without any other sensors, gamepad or remote controller held in hand. The goals of this thesis are as follows. First, the 3D environment is developed. Second, using image detection techniques to obtain the position of user’s face and change 3D view according to the moving of user’s face such that the user sees a real object in front of his face. Finally, the user holds a color flashlight. The moving direction of the flashlight is detected and then makes the 3D objects move following the moving direction of the flashlight. The most important achievement of this thesis is that there is much interaction between user and computer in 3D environment without any gamepads and sensors except a webcame. These techniques can be applied to not only 3D games, but also any other virtual realities. Furthermore, it does not need a special-make monitor or 3D-glasses.
