龍門核電廠運轉員情境察覺衡量方法之探討

目前有許多情境察覺衡量方法能測量出操作人員在一定時間與空間下，是否有察覺到重要資訊，進而去理解其含義並且預測其在不久所將會發生的情況。本研究回顧各類情境察覺衡量方法，比較各類方法之特性後，挑選有別於主觀衡量方式並具有客觀且量化的情境察覺衡量方法，評估龍門核電廠主控室中觸控式螢幕(VDU)SPDS 092不同的顯示介面對於受測者在執行水位監控任務的情境察覺程度是否有所差異，並以SAGAT搭配凝視追蹤技術之衡量法所蒐集的量化數據來解釋為何有其差異，以彌補SA-SWORD主觀評比方式對於數據解釋能力較不足之處。研究結果顯示，受測者對於龍門核電廠新、舊介面資訊判讀的情境察覺程度有所差異，受測者在新介面的情境察覺答題正確率為舊介面的1.92倍，更進一步獲悉受測者在執行監控任務時所關注的區域及注意力的分布情形，受測者在新介面的搜尋異常值時間為舊介面的0.3倍，受測者在新介面的凝視重要資訊百分比(％)為舊介面的5.58倍。根據上述結果，本研究使用SAGAT(探測法)與凝視追蹤技術(生理參數衡量法)之結果與龍門核電廠運轉員使用主觀評比結果一致，為一客觀且有效衡量情境察覺之方法，並可進一步以量化的方式詮釋情境察覺程度差異之所在；評估新設計的介面時，在尋找受測者方面較為簡單，並非需要運轉員作為受測者，以工學院學生作為受測者也可獲得一致之結果。

There are many situational awareness measurements to measure whether operators are aware of environmental elements within a volume of time and space, comprehend their meaning, and predict their status in the near future. The purpose of this study is to review various types of situational awareness measurements, and then select possible and effective measurements for the Video Display Unit screen SPDS 092 which was the reactor water level monitoring screen in the Lungmen Nuclear Power Plant main control room. In this study, the SAGAT with gaze tracking technology was applied to measure operator situation awareness, and the results were compared to the results from the SA-SWORD (subjective rating methods) measurement in a previous study. Results showed that the subjects’ SA scores with the new interface was 1.92 times higher than with the original interface. The subjects’ search times with the new interface was 0.3 times faster than with the original interface, and the subjects’ gaze percentage on important information with the new interface was 5.58 times higher than with the original interface. Further, the results of this study used SAGAT (probe measurement) with the gaze tracking technology (physiological parameter measurement) were consistent with operators’ results used SA-SWORD. In other word, the measurement in this study was an effective measurement, and it could further quantify the degree of difference in situations awareness; evaluate the new design interface.
