摘要

虛擬實境系統由於其本身並不受地點以及空間的限制，虛擬情境可以彈性變化，具有方便以及安全等特性，常用於「娛樂」或是「模擬訓練」等方面。
在本文中我們就以飛艇當作一個例子來說明所製作的運動模擬機。利用虛擬實境的運動模擬機取代實機飛行測試來訓練飛行駕駛員可解決其龐大花費及高危險性的問題，而設計良好的虛擬實境動態模擬系統可提供駕駛員擬真的即時互動環境，使其有身歷其境的感受。

做法方面：先設計控制搖桿，把輸訊號藉由搖桿來控制馬達，之後把訊後由程式傳送給虛擬實境作運算，在把值傳送給輸出馬達來作出使用者想要的動作。

結果方面：成功得研發出一套運動模擬系統和一套MATLAB模擬系統，此系統可以事先預測機構的運動情形並減少實際操作時犯錯的機會。


本論文主要特點有下列三點:
1. 低自由度模擬高自由度
2. 有限空間模擬無限空間
3. 視覺頭盔:可以使玩家有更好的視覺效果

Abstract

Virtual solid Jing system due to it also be free from the restriction of location and space, virtual scenario can flexible variety, have characteristics, such as convenience and security...etc., in common use at the aspects such as"amusement" or"imitate train" etc..

In this text we regard as an example by dirigible airship to explain exercise manufactured to imitate machine.Making use of the exercise of virtual solid Jing emulation machine's replacing solid machine to fly to test's canning solve its problem of huge cost and high risk, and designing a good virtual solid Jing dynamic state emulation system to training flight a pilot can provide a pilot to draw up to really and immediately interact environment, making it have the feeling for experiencing personally.

Modus: Design control joystick first, lose a signal by joystick to control motor, after Xun behind is delivered by the program to make an operation for conjecture solid Jing, is delivering the value to output motor to make the action that the user wants。
Result: Succeed develop the emulation system of a set of exercise and a set of MATLAB to imitate system, this system can in advance predict the exercise situation of organization and reduce actual operation hour make mistake of chance.

The main distinguishing feature includes following 3 point

1：The low freedom degree imitates a high freedom degree

2：The limited space imitates infinite space

3：Vision helmet:can make the player have a better visual effect
