Researchers have developed Pro$^2$Assist, a new multimodal large language model system designed to offer continuous, step-aware proactive assistance for complex, long-horizon procedural tasks. Unlike previous assistants that are mostly reactive, Pro$^2$Assist uses data from AR glasses to perceive user actions and understand task progress in real-time. The system extracts procedural context from temporal dynamics and expert knowledge to infer user needs and provide timely guidance, outperforming existing methods in action understanding and proactive timing accuracy. AI
