Natural interaction in VR/AR is achieved through AI technologies that interpret human gestures, facial expressions, and voice inputs. AI-powered gesture recognition systems analyze movement patterns using machine learning models, enabling intuitive control without the need for physical controllers. Facial recognition and emotion detection algorithms allow virtual avatars to mimic real-time expressions, enhancing social interactions in VR spaces. Voice recognition systems powered by Natural Language Processing (NLP) enable users to communicate naturally with virtual assistants and in-game characters. This seamless integration of AI-driven interactions fosters a more engaging and lifelike VR/AR environment.
