About

HeiCo-FOCUS comprises 30,000 visual question answering pairs derived from 96 hours of Heidelberg Colorectal surgery videos. It was constructed via a rigorous pipeline involving crowd annotation and 39 surgical experts to ensure clinical relevance.

The benchmark evaluates five capabilities including temporal grounding and procedural understanding. Experiments show models struggle with temporal grounding (19.7% accuracy) while performing better on event understanding (56.5%), indicating the task is far from solved.
