STACK: 3D Spatial Task Analysis in Collaborative Construction Keyframes

Analyzing multi-party physical collaboration means tracking what a group builds and whether their actions move the shared structure toward a goal. Vision-Language Models (VLMs) could automate this analysis from session recordings, but existing spatial-reasoning benchmarks use rendered scenes or curated snapshots, not r...
