Visual TL;DR
Zero-shot video QADriver
From the article 5 mentionsEgocentric video spatial question answering demands sophisticated reasoning over 3D object positions and scene affordances, a challenge amplified in the zero-shot setting.
SpatioRoute VLMCore
novel dynamic prompt generation approach for video QA
From the article 4 mentionsThis flexibility allows SpatioRoute VLM to adapt to diverse question types and contextual nuances, enhancing zero-shot capabilities.
Question-Aware RoutingContext
two complementary routing mechanisms for prompt tailoring
From the article 3 mentionsFurthermore, the research highlights a critical finding: Chain-of-Thought (CoT) prompting, specifically with the Think it Twice architecture, actually degrades performance on Qwen series models in this context, underscoring the superiority of question-aware routing over uniform reasoning strategies for spatial video understanding.

From the articleFurthermore, the research highlights a critical finding: Chain-of-Thought (CoT) prompting, specifically with the Think it Twice architecture, actually degrades performance on Qwen series models in this context, underscoring the superiority of question-aware routing over uniform reasoning strategies for spatial video understanding.
SpatioRoute-RCore
From the articleSpatioRoute-R employs a rule-based system to deterministically map question typologies (e.g., 'What', 'Is', 'How') to specialized prompt templates.
SpatioRoute-LCore
From the articleComplementing this, SpatioRoute-L utilizes an LLM to generate task-specific prompts based solely on the question and situational context, crucially not requiring video input at the routing stage.
Dynamic PromptingContext
From the article 2 mentionsThis paper introduces SpatioRoute, a novel dynamic prompt generation approach that tailors prompts to incoming questions without any additional training or 3D inputs.
