人機(計算機)交互(Human-Computer Interaction)系統包括人、計算機輸入、輸出設備及其相應人機界面(Human-Computer Interface )。本文針對一種筆式三維人機交互系統進行了研究，用二自由度機械跟蹤器、DSP數據采集器、藍牙通信模塊、PC 機以及研制的界面軟件，設計了一種三維人機交互設備,系統能夠比較真實的模擬筆在紙面上的運動軌跡,在一定的硬件條件下，系統能夠較好地完成實時交互，同時交互過程中能夠保證良好的手感。

Based on OpenGLMan-machine Interaction System Design Li jinhmin (JiLin Business and technology college Jilin changchun 130062) Astract: Human-Computer the computer and its interaction(HCI) system contents the human, I/O Devices of Human-Computer Interface. This paper researches a pen-based 3D-HCI system. . It has designed one kind of three dimensional man-machine interaction equipment which consists of a 2 degrees,mechanical tracker, DSP device, bluetooth, PC and the interface software. Under certain hardware condition, the system can complete well real-time, simultaneously is alternately interactive in the process to be able to guarantee the good feel.
