IPIBench - Reactive-to-Proactive: leaderboard
Metric: Accuracy (%) on reactive-to-proactive interaction (start tracking a new task from a reactive exchange), on IPIBench (1,831 videos, 3,738 interaction instances from egocentric and exocentric datasets) under a unified streaming protocol at 1 FPS (offline models see a sliding window of the latest 16 frames); a proactive response counts only if the first trigger falls within one second of the ground-truth moment, multi-turn tasks only if every required trigger and answer is correct, reactive answers by bidirectional substring matching against up to 20 reference answers; higher is better. Source: arxiv.org. Saturation forecast: Around August 2028. 11 models tracked.
