爲瞭解頭配顯示器(Head Mounted Display, HMD)對人體生理影響與相關產品的設計和開發，本研究首先以自行設計的心律檢測系統配合疲勞度視覺問卷，對年輕受測者進行視覺機能與不適性的感覺模擬實驗和分析，並藉由觀看不同類型影片，監測受測者心律變異度、視覺疲勞度、目標追蹤以及瞳孔距離(Inter-Pupillary Distance, IPD)改變情形。根據本研究量測獲得之資料分析結果，顯示長時間使用頭配顯示器，確實對使用者造成生理機能上的負面影響，其中包括心率變化量有明顯的改變、交感神經與副交感神經均呈現顯著的變化、在快速移動下容易造成眼部肌肉疲勞與視覺不適性等。為改善因瞳孔距離不良所造成視覺不舒適性部分，後續利用電腦輔助整合設計進行可調式瞳孔距離同動機構的設計與運動模擬分析，並配合產品意象尺度(Image Scale)、產品設計方法及理論等完成產品的設計與開發。最後，則依據測試之結果與實際產品設計開發過程之經驗，提供此產品的相關設計準則，作為產品開發單位在設計上之參考依據。

To understand the physiological effects of head-mounted display (HMD) on human, experiments were conducted to measure the subjects' heart rate variability (HRV), degree of visual exhaustion, eye-movement tracking, and inter-pupillary distance (IPD) while watching different types of films. All subjects were also asked to complete a questionnaire after each experiment. Experimental results reveal that the use of HMD indeed poses negative physiological effects, including visual discomfort and fatigue after long-term viewing of the HMD screen. To overcome such drawbacks, an adjustable IPD mechanism for motion simulation analysis was developed using computer-aided integrated design system. Finally, a HMD product was designed according to product image scale, products design method and theory. Results of this study can serve as useful references for HDM design.
