Emotion in perception 、 Decision making 、 Logical reasoning and social interaction play a central role in a series of intelligent activities , It is to realize human-computer interaction and machine intelligence Important elements . In recent years , With the explosive growth of multimedia data and the rapid development of artificial intelligence , Affective computing and understanding have attracted widespread attention . emotional Calculation and understanding are designed to give computer systems recognition 、 understand 、 The ability to express and adapt people's emotions to establish a harmonious man-machine environment , And make the computer more high 、 More comprehensive intelligence . According to the different input signals , Affective computing and understanding contain different research directions .  This paper comprehensively reviews multimodal affective cognition other 、 Autism emotion recognition 、 The research progress of different emotional computing and understanding directions such as emotional image content analysis and facial expression recognition in the past few decades And prospects for the future development trend . For each research direction , Firstly, the research background is introduced 、 Problem definition and research significance ; Secondly, from different angles The international and domestic research status are introduced respectively , Including emotional data annotation 、 feature extraction 、 Learning algorithms 、 The performance comparison and analysis of some representative methods are And representative research teams ; Then the research at home and abroad is systematically compared , The advantages and disadvantages of domestic research are analyzed ; Finally, the existing problems of current research are discussed Problems in and future development trends and prospects , For example, consider individual emotional expression differences and user privacy issues .

 

emotional (emotion) The word comes from Greek “pathos”, Earliest Used to express people's sentimental feelings about tragedy . Emotion in perception 、 " Strategy 、 Logical reasoning and social interaction play a central role in a series of intelligent activities effect , There are even studies showing “ In human communication 80% All information It's emotional information ”. Because of the importance of emotion in human information communication Great significance , Emotional computing is essential to realize human-computer interaction Part of , It is also an important breakthrough to make machines intelligent . emotional The concept of computing was developed by the Media Laboratory of Massachusetts Institute of Technology Picard Professor proposed , And in 1997 Books were officially published in 《 Affective Computing( Emotional computing )》. In the book ,Picard Professor pointed out “ Emotional computing is related to emotion , Come from emotion or be able to love The calculation of the effect of sense ”, It pioneered the research of emotional Computing . Affective computing and understanding aims to give computer systems recognition 、 understand 、 surface The ability to reach and adapt to human emotions to establish a harmonious man-machine environment , and Make the computer have higher 、 More comprehensive intelligence . According to the different input signals , Affective computing and understanding contain different research directions .

Better parallel computing efficiency and better modeling long-distance features potential . The research of multimodal emotion recognition can further improve people Quality of life . In terms of public opinion analysis , It can analyze the user's The emotional tendency of events such as COVID-19 ; In business intelligence , can To analyze users' satisfaction with goods , Design causes users to accumulate Extremely emotional advertising ; In terms of health , Can analyze driving 、 attend class;class begins The degree of emotion in such a state , Give targeted warnings , Improve the quality of work Efficiency .
