Emotional AI is becoming an emerging trend in the enterprise software domain, aiming to enable AI assistants to understand human emotions and enhance the intimacy of human-machine interaction. This technology attempts to accurately interpret emotions in interactions by combining multidimensional data such as visual and auditory inputs, utilizing machine learning and psychological knowledge. With the widespread application of AI assistants in the workplace, emotional AI shows greater commercial potential. Many large cloud service providers have launched related services, such as Microsoft's Azure Cognitive Services and Amazon's Rekognition. However, emotional AI is not a new concept.
