The "Emotion Engine" is a type of artificial intelligence designed to recognize and respond to human emotions. It uses various techniques, such as natural language processing and facial recognition, to interpret emotional cues from users. This technology aims to create more engaging and personalized interactions in applications like customer service, gaming, and mental health support. Developed by companies like Sony and IBM, the Emotion Engine can analyze text, voice tone, and visual expressions to gauge feelings. By understanding emotions, it can tailor responses, making conversations feel more natural and empathetic. This innovation is part of a broader trend toward emotionally intelligent machines.
