情感能力是人类智能的重要标志,情感的缺失会影响网络远程教育的教学质量和学习者的学习效果.情感计算是和谐人机交互与人工智能领域中新的研究方向.在网络远程教育系统中应用情感计算理论与技术,可以进一步优化网络远程教育的功能,帮助教师监测远程学习者的情感变化,调整教学策略和方法,实时给予学习者情感反馈,使教学质量达到最佳.目前国内外情感计算在远程教育方面的应用研究还处于起步与探索阶段,所构建的远程教学系统对远程教学中师生情感生理特征与心理特征、多模情感信息融合机制及网络虚拟人机情感交互特性等考虑不足,系统原型在情感合成与表达、智能人机情感交互实现上存在着很大的难度.因此,构建与人类情感系统相吻合的、自然和谐的、人性化和智能化的网络远程教育系统,需要有效解决师生面部表情、语音情感特征信号的准确识别与提取,师生多模情感信息融合机制与和谐人机情感交互技术等关键问题.
情感能力是人類智能的重要標誌,情感的缺失會影響網絡遠程教育的教學質量和學習者的學習效果.情感計算是和諧人機交互與人工智能領域中新的研究方嚮.在網絡遠程教育繫統中應用情感計算理論與技術,可以進一步優化網絡遠程教育的功能,幫助教師鑑測遠程學習者的情感變化,調整教學策略和方法,實時給予學習者情感反饋,使教學質量達到最佳.目前國內外情感計算在遠程教育方麵的應用研究還處于起步與探索階段,所構建的遠程教學繫統對遠程教學中師生情感生理特徵與心理特徵、多模情感信息融閤機製及網絡虛擬人機情感交互特性等攷慮不足,繫統原型在情感閤成與錶達、智能人機情感交互實現上存在著很大的難度.因此,構建與人類情感繫統相吻閤的、自然和諧的、人性化和智能化的網絡遠程教育繫統,需要有效解決師生麵部錶情、語音情感特徵信號的準確識彆與提取,師生多模情感信息融閤機製與和諧人機情感交互技術等關鍵問題.

Emotion ability is an important symbol of human intelligence. Emotion absence can affect the teaching quality of web-based distance education and the learning effect of learners. Affective computing is a new research direction of the natural human computer interaction and artificial intelligence field. In web-based distance education system, the application of affective computing theories and techniques can further enhance the function of web-based distance education, help teachers monitor the emotional changes of distance learners and adjust teaching strategies and methods. It can also give real-time affective feedback to learners, leading to the optimization of the teaching quality. So far, the applied research of affective computing on distance education at home and abroad is at its beginning and exploring stage. In the constructed distance education system, sufficient attention has not been paid to physiological and psychological characteristics of the emotion between the teachers and students, to multimodal mechanism for emotional information fusion, or to characteristic of network virtual human computer emotion interaction. The distance education system prototype has great difficulties in aspects of emotional synthesis and expression and realization of intelligent man-machine emotion interaction. Therefore, in order to construct a natural, humanized and intellectualized web-based distance education system consistent with human emotion, it is necessary to realize the key techniques on correct recognition and extraction of facial expressions and voice signals of teachers and students, multimodal mechanism for teacher-student emotional information fusion and natural human computer interaction.
