SPATIOROUTE: Dynamic Prompt Routing for Zero-Shot Spatial Reasoning

In three linesSpatioRoute is a dynamic prompt routing approach for spatial question-answering over egocentric video. Without fine-tuning, it routes each question to a specialized prompt template (rule-based or LLM-driven mode) and achieves +5% accuracy gains on SQA3D versus fixed baselines, establishing SOTA for zero-shot video-only spatial VQA without 3D point-cloud inputs.
