summary

EchoLadder is a VR authoring pipeline that breaks vague verbal prompts into executable suggestions using a large vision-language model and a JSON action layer so users can apply / undo / regenerate modifications. It matches added objects from a pre-annotated asset library of 2,000+ assets and runs a labeling module that uses LMs to produce object metadata. An ablation with 18 participants and a user study with 12 participants show higher inspiration, relevance, and perceived control versus end-to-end auto-generation.
