本研究中嘗試監測較短時間(<10sec)的生理資訊,期望以一近乎即時的方式判讀並回饋使用者適當的資訊,對於生理訊號與情緒狀態的關聯性研究,將以IAPS(International Affective Picture System) 素材為來源,進行較過去嚴謹的實驗設計與程序,以探究生理訊號特徵如何應用於情緒分類。
Physiological signals can be used to measure a subject’s response to a particular stimulus, and infer the emotional status accordingly. This research investigates the feasibility of emotion recognition using physiological measurements in a smart living space. It also addresses important issues regarding the integration of classification results from multiple modalities.
Most past research regarded the recognition of emotion from physiological data as a mapping mechanism which can be learned from training data. These data were collected over a long period of time, and can not model the immediate cause-effect relationship effectively. Our research employs a more rigorous experiment design to study the relationship between a specific physiological signal and the emotion status. The newly designed procedure will enable us to identify and validate the discriminating power of each type of physiological signal in recognizing emotion.
Our research monitors short term (< 10s) physiological signals. We use the IAPS (International Affective Picture System) as our experiment material. Physiological data were collected during the presentation of various genres of pictures. With such controlled experiments, we expect the cause-effect relation to be better explained than previous black-box approaches.
Our research employs dimensional approach for emotion modeling. However, emotion recognition based on audio and/or visual clues mostly adopt categorical method (or basic emotion types). It becomes necessary to integrate results from these different modalities. Toward this end, we have also developed a mapping process to convert the result encoded in dimensional format into categorical data.
