TLDR

This paper defines visual UI grounding, where a model must localize the UI element referenced by a natural-language command directly from a screenshot without relying on UI metadata. It proposes LVG, which combines layout-guided contrastive learning with synthetic-to-real multi-context learning and improves top-1 accuracy by more than 4.9 points over strong baselines.
