| 摘要: | 本研究藉由模擬室內讀書環境，透過檯燈及吸頂燈建構出不同環境照度均勻度作為閱讀情境，以僅開檯燈的集中光、只開吸頂燈的均勻光以及檯燈及吸頂燈皆使用的混合光，探討不同照明情境下對使用者的生心理影響以及專注程度差異。本研究將承襲實驗室先前所使用的照明人因評估技術，招募受試者進行靜態紙本測驗，分析所設計之情境對受試者的影響。
數據量測方面，使用Neurosky腦波儀量測並記錄受試者在照明情境下進行智力測驗、d2-test及休息時的腦波訊號以利後續分析。實驗分析中利用了經驗模態分解法(empirical mode decomposition, EMD)、希爾伯特轉換(Hilbert transform, HT)、機率密度函數(probability density function, PDF)以及接收者操作特徵曲線(receiver operating characteristic curve, ROC curve)進行運算。客觀指標為智力測驗與d2-test作答情形、接收者操作特徵曲線的曲線下面積(area under the curve, AUC)以及特徵指標轉換專注度成績；而以受試者填寫的自我評估問卷作為主觀指標，並且將主客觀指標匯入SPSS統計軟體進行變異數分析，檢定以上指標在不同情境間是否具有顯著差異，進而探討照明對受試者之影響。
研究結果顯示在客觀指標上，受試者在不同情境間，專注與休息時的腦波並無明顯的分類差異，在智力測驗及d2-test作答情形上，不同情境間並無明顯差異，但d2-test有練習效應的產生。從專注度成績換算中可以得出，受試者於均勻光情境時，進行專注活動比較無法進入狀態，而休息時處於集中光情境比較難以放鬆。而就主觀指標而言，對於環境照明的喜好程度皆為混和光最優，並且眼睛最也不容易感到乾澀痠痛。
;This study simulates an indoor reading environment by using desk lamps and ceiling lights to create different illuminance uniformity conditions as lighting scenarios. These scenarios include focused light with only the desk lamp on, uniform light with only the ceiling light on, and mixed light with both the desk lamp and ceiling light on. It aims to explore the physiological and psychological effects of lighting on users and the differences in users’ levels of concentration under various scenarios. The study will adopt the lighting human factors assessment techniques previously used by the research team in the laboratory. Participants will be recruited to take static paper tests, and the impact of the designed scenarios on the participants will be analyzed.
In terms of data measurement, a Neurosky EEG device will be used to measure and record the participants′ brainwave signals while they perform intelligence tests, d2-tests, and during rest sessions in different lighting scenarios to facilitate subsequent analysis. The experimental analysis will employ empirical mode decomposition (EMD), Hilbert transform (HT), probability density function (PDF), and receiver operating characteristic curve (ROC curve) for computation. Objective indicators include the performance on intelligence tests and d2-tests, the area under the curve (AUC) of the receiver operating characteristic curve, and the attention score derived from brainwave features. Subjective indicators will be based on self-assessment questionnaires filled out by the participants. Both objective and subjective indicators will be analyzed using statistical software SPSS to conduct variance analysis and determine whether there are significant differences among the different scenarios, thereby investigating the impact of lighting on the participants.
The results indicate that, in terms of objective indicators, there is no significant classification difference in brainwaves between different scenarios during concentration and rest. The performance on intelligence tests and d2-tests also shows no significant differences between scenarios, although there is a practice effect observed in the d2-test. The calculation of attention scores reveals that participants find it harder to concentrate during focused activities in uniform lighting scenarios, and they find it harder to relax during rest sessions in concentrated lighting scenarios. Regarding subjective indicators, mixed lighting is preferred for environmental illumination, and participants report that their eyes are less likely to feel dry or strained. |
