MotionHalluc: Diagnosing Kinematic Hallucinations in Fine-Grained Motion Reasoning

Researchers introduce MotionHalluc, a benchmark dataset for evaluating how AI models hallucinate when analyzing motion differences between paired videos. The study reveals that large multimodal models struggle with directional, attributional, and temporal hallucinations in motion reasoning, but shows that injecting explicit kinematic measurements can improve accuracy by 10.6%.
