The Robot Reconsidered Intent Only When the Task Changed
HINT separates sparse semantic decisions from continuous object-hand tracking in long-horizon manipulation.
Summary
HINT separates sparse semantic decisions from continuous object-hand tracking in long-horizon manipulation.
The framework invokes semantic reasoning at manipulation-pattern transitions to select the subtask and target, then holds that commitment through multiview grounding and visual tracking. It can pass the tracked intent through either image-space highlighting or attention-prior injection without training the foundation action model. Across three long-horizon tasks and out-of-distribution variants, the authors report higher intent understanding, progress and completion for two policies while preserving low-latency control.
Why it matters
HINT separates sparse semantic decisions from continuous object-hand tracking in long-horizon manipulation.
