WatchAct - Implicit Intent Inference: leaderboard

Implicit intent inference in WatchAct (Li et al., 2026): a vision-language model watches a person's gestures, hand motions or ambiguous references and writes a high-level robot plan for the intended task. The plan is executed symbolically in an aligned LIBERO scene; plan success rate in percent over 455 instances, higher is better.

Metric: Plan success rate (%; the VLM's high-level Pick/Place/Open/Close plan, predicted from a real human video and an instruction, run through a symbolic executor and checked against the task's success predicate; instance-weighted mean of the Nonverbal Cue and Reference Disambiguation tasks, 455 instances). Source: arxiv.org. Saturation forecast: Around February 2027. 9 models tracked.
