在日常生活中，壓力是無所不在的，所伴隨的相關情緒上的變化例如緊張、焦慮也更是常被忽略的。焦慮不只是心理上或情緒上的感覺而已，它還會對身體的功能造成某種程度的影響。站在預防醫學的立場，面對從四面八方來的內外壓力，要正視它，讓健康危害的程度降低到最小。
　　本研究主要是量測與記錄末稍血流、眉心肌電訊號等生理訊號，並做各生理參數相互間的分析，且找出受測者的生理變化趨勢。本研究以PC為發展系統，建立生理參數的量測技術並將其模組化，且透過電腦介面整合在一起。以LabVIEW為軟體的撰寫工具，找出各生理訊號與生理狀況的相互關係，作為研判參考之用。
　　在動態實驗中，當遭遇生理壓力時，焦慮組需要較多的時間回復；在靜態實驗中，在眉心EMG部分，因工作關係，焦慮組所量測的數據較基準值高出76％，諧波分析也隨著工作時數加長，而越容易產生不規則的變化。

　　In the daily life, the pressure is omnipresent. How to detect the pressure source then further guard against it to cause the damage is a very important study topic for each person nowadays. Simultaneously following the pressure is those related mood change, ex: intense, anxious are also often neglected. Anxious is not only a feeling in psychological or mood, it but can create influence to the body function. In the preventive medicine standpoint, facing the pressure which comes in all directions, understanding it and unblocking it, finally conquering it is the only way to reduce the danger from health .
　　The purpose of this study is to measure and record the several physiological activities (such as heart rate, peripheral blood flow waveform and eyebrow electromyography), and also to examine the relationship among them, then show the status of patient with animation. The aim of the research is to construct a virtual medical equipment environment in a personal computer to measure those physiological activities. The LabVIEW software is used to collect and organize the data.
