A real-time emotion recognition system for individuals could be implemented with related bio-information. In this research, specific music is chosen to elicit the user’s emotions (relaxed, positive and negative). The physiological signals were acquired through four biosensors: electromyogram, skin conductance, respiration and pulse. Physiological features are acquired by features extraction methods such as filtering, segmentation, calibration and normalization. At the same time, physiological features are classified using pattern recognition techniques. The accuracy of off-line analysis achieved 95.61% and 91.69% on recognition of “relaxed vs. excited” and “positive vs. negative”, respectively. Besides, our results show the tendency of user’s skin conductance responses matches other research results.urthermore, the accuracy of real-time analysis are 94.69% and 81.00% on recognition of “relaxed vs. excited” and “positive vs. negative”, respectively. Finally, the limitations of real-time emotion recognition for individual are listed and will be solved in the future; there are still some works need to be optimized formplementation of a real-time emotion recognition system for individual.目錄試委員會審定書….…………………………………………… i謝 ……………………………………………………………... ii文摘要 ………………………………………………………... iii文摘要 ……………………………………………………….. iv目錄 ………………………………………………………….. v目錄 …………………………………………………………... vi一章 緒論 ………………………………………………….. 1.1 研究背景 ……………………………………………….. 1.2 研究主題 ……………………………………………….. 2.3 情緒辨識相關文獻回顧………………………………… 3.4 論文架構 ……………………………………………… 7二章 生理訊號相關理論……………………………………. 8.1 交感神經與副交感神經系統…………………………… 8.2 情緒狀態與生理反應關聯性…………………………… 9.3 使用者生理訊號及其特徵 …………………………….. 11.3.1 肌電圖 ……………………………………………. 11.3.2 呼吸 ………………………………………………. 13.3.3 脈搏 ………………………………………………. 14.3.4 表面皮膚導電反應 ………………………………. 16.3.5 生理訊號特徵值 …………………………………. 17三章 研究方法………………………………………………. 19.1 研究方法流程 ………………………………………….. 19.2 實驗設計 ……………………………………………….. 20.3 生理訊號濾波與切割 ………………………………….. 22.4 生理訊號特徵校正與正規化 ………………………….. 25.5 資訊交叉比對 ………………………………………….. 26.6 分類演算法: KNN ……………………………………… 27.7 特徵分析演算法-資訊增益 ………………………….. 28.8 單人即時情緒分析系統 ……………………………….. 30四章 結果 …………………………………………………... 31.1 單人的離線分類結果 ………………………………….. 31.2 單人情緒狀態與特徵關聯性 ………………………….. 38.3 單人即時情緒辨識結果 ……………………………….. 41五章 討論、結論與未來展望 ……………………………… 47.1 討論 …………………………………………………….. 47.2 結論 …………………………………………………….. 52.3 未來工作 ……………………………………………….. 52amp;#63851;考文獻 ………………………………………………………... 54錄 ……………………………………………………………... 563829692 bytesapplication/pdfen-US音樂情緒辨識即時生理訊號人機互動MusicEmotion recognitionReal-timePhysiological signalsHuman-computer interaction以生理訊號分析系統即時評估音樂環境之使用者情感反應Estimation of User’s Affective Response on Musicontents Using Real-Time Analysis System of Physiological Signalsthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/188094/1/ntu-98-R95921104-1.pdf
