摘要

有鑑於自動化設備的普及與近年來工廠生產線逐漸轉變為客製化、低產量的生產型態，使得物件有更小且複雜的趨勢，在品檢上人工目視檢驗（Visual inspection，VI）仍是較有效的方法。照明環境是影響視覺感官的主要因素之一，不同的光將產生出不同的生心理情緒變化及視覺感受，因此本研究將探討人於不同色溫照明環境下進行目檢作業時，對於生心理反應與工作績效之影響，以兩種照明環境（4000K750lx和5600K750lx）做為研究變項，透過模擬目檢作業並蒐集目檢任務中的生理變化（皮膚電反應、皮膚溫度和心率）、眼球運動（停留與凝視次數）、視覺疲勞（主觀問卷）與工作績效（總產量、訊號偵測理論，SDT），藉以分析在兩種照明環境時對於檢驗作業上的影響。本研究結果顯示，兩種照明對目檢的工作績效表現並無明顯變化；但於4000K750lx照明環境下，檢驗缺陷晶粒時生理反應呈現專注以及產生更高的視覺疲勞；反之在5600K750lx照明環境下，則發生高喚醒以及較低的視覺疲勞感受。因此對於目檢任務，環境色溫的不足將影響人員的生理以及視覺感受。

During the last few decades, automatic manufacturing makes the product smaller and more complex. Consequently, visual inspection is still an efficient method of quality control. Besides, visual performance has mainly been affected by the environment lighting, different lighting conditions may have caused the different psychophysiological effects. This paper examines the psychophysiological response and working effect of the visual inspection task under two different correlated color temperature (CCT) lighting. The research experiment with the inspect wafer defects was carried out in a 4000K 750lx and 5600K 750lx a LED lighting environment. During the inspection task, the direction to participants' physiological signal (Skin Conduction Level, Skin Temperature, and Heart Rate), subjective visual fatigue (Subjective Questionnaire), work performance (Signal Detection Theory, SDT), and eye movements (Number of Fixation and Number of Dwell) were collected to compare subject’s performance in two lighting conditions. The results showed that CCT had no effect on the working performance of inspection tasks. When lighting condition with 4000K 750lux, compared to 5600K 750lux, the psychophysiological became focused and the visual fatigue was higher. Besides, the physiological arousal will increase after the inspection task with 5600K. Therefore, for inspection tasks, the CCT significant impact on the psychophysiological response and subjective visual fatigue. These findings have implications for visual inspector tasks and inspectors.
