中文摘要 根據定義,情緒是受到某種刺激所產生的身心激動狀態。現代人在忙碌的工作下,常常累積許多壓力,當一個人累積過多壓力後,常常因為沒有適當的宣洩壓力,而將這個刺激表現在情緒上,往往造成同事、同學間的口角,引起許多誤會。情緒會引起如交感神經、副交感神經和心率的變化的生理反應及如開懷大笑、愁眉苦臉等表情反應。為了能夠辨別情緒,本研究主要建立一套量測系統,透過ZigBee無線傳輸來傳送所量測到的生理參數,並分析之。
雖然臉部表情來辨識情緒有一定的可行性,但一個經過訓練的人可能做出假的表情來造成系統誤判,最直接的方式就是測量生理訊號,生理反應源自自律神經系統,沒有辦法造假,所以本系統採用生理訊號分析來取代臉部表情辨識。而最能夠代表情緒的生理參數就是心電圖訊號,利用無線傳輸將收集到的ECG訊號送到電腦端作心率變異率(HRV)分析,再藉由這些參數的趨勢來判斷目前處於正面情緒或是負面情緒;另外也使用最近鄰居(KNN)分類器來將參數作分類,並與SAM量表作比較。若是準確率高,就可以使用本系統達到情緒辨識的目的,擺脫使用問卷來判斷情緒的方法。
英文摘要 By definition, emotion is an excited state generated by some kind of physical and mental stimulation. Under the busy works in modern time, a lot of people accumulate heavy pressure. When a person accumulated too much pressure, and no proper manner to vent pressure, it may be presented on emotional responses, and often resulting in a quarrel with colleagues or students. Finally, it may also lead to a lot of misunderstanding. The emotion will cause physiological and expression responses. The physiological responses are such as sympathetic, parasympathetic and heart rate (HR) changes. The expression responses are such as laughing face, frown, etc. In order to identify emotions, this study establishes a measurement system of physiological parameters and transmit the measured data through ZigBee wireless transmission systems and then analyzing the physiological parameters.
Although face recognition authentication has some viability, a trained person may make a false expression, and cause the system’s recognition error. The most direct way is to measure physiological signals. As the physiological responses are originated from Autonomic Nervous System (ANS), it is impossible to fake. Therefore, the system uses the physiological signal analysis instead of the facial expression recognition. Furthermore, the most suitable physiological parameter to represent emotional responses is the ECG signal. By using wireless transmission, it can transmit the measured ECG signal to the PC for heart rate variability (HRV) analysis. And then we use these parameters to determine the current trend of positive emotions or negative emotions. In addition, we also use the nearest neighbor (KNN) classifier to classify other parameters and compare with the SAM scale. If it has high accuracy, you can use this system instead of questionnaires to recognize the emotional responses.
