    摘要: 目前偵測一般人情緒的方式大部分在研究人的行為,例如:臉部表情,以及分析人體的各項生理數值,例如:心跳、體溫以及呼吸頻率。然而這些研究只單純探討人的外在行為或生理訊號在不同情緒下的變化,而人的眼睛包含外在行為跟生理訊號,本研究將探討不同情緒下眼睛有什麼特別的反應。
    我們先制訂一套實驗流程,在流程中我們以不一樣的情緒圖片給予受測者刺激,然後記錄受測者的眼動反應,並且讓受測者回報自己的情緒狀態。本研究也記錄受測者在情緒刺激下的眼動反應,並將眼動之反應轉換成序列資料,再針對不同情緒下的序列建立隱藏馬可夫模型(Hidden Markov Models:HMM)。希望藉著情緒模型,從眼動行為中偵測受刺激者處於何種情緒狀態。
    本研究發現人在看圖時會依據對圖片內容的好惡,產生有意義的眼動反應。我們利用相對應的眼動反應建立情緒辨識系統,在辨識三種情緒時,辨識率能夠達到六成。
