Where spatial state breaks: a minimal-pair pilot on viewpoint reasoning in multimodal models
Using synthetic 3D scenes with geometry-derived ground truth, I ask counterfactual viewpoint questions to isolate where a model's spatial representation becomes inconsistent — projected position, depth ordering, visibility, or viewpoint-dependent relations — and compare against simple human sanity checks.
The longer-term question is about interaction: can external, editable representations help people and models establish and preserve a shared spatial state? This is the direction I hope to pursue in doctoral study.
