Emotion AI, also known as affective computing, refers to technology that can recognize and interpret human emotions. It uses algorithms and machine learning to analyze facial expressions, voice tone, and body language, allowing machines to understand emotional states. This technology is increasingly used in various fields, including customer service, healthcare, and entertainment. By understanding emotions, Emotion AI can enhance user experiences and improve interactions between humans and machines. For example, it can help virtual assistants respond more empathetically or enable video games to adapt to players' feelings, creating a more immersive experience.
