Progress on this problem has been limited, in part because no dedicated benchmark or dataset exists to define and evaluate it....

Contextual Observer Grounding: Evaluating Situated Spatial Reasoning in Vision-Language Models

Reasoning over language instructions in embodied tasks such as robotics often requires understanding spatial relations from a speaker's situated perspective. Humans infer such perspectives from shared environmental knowledge, activity context, and commonsense. Recent vision-language models (VLMs) appear capable of spat...

Lost in Reconstruction: Aligning Action Representations with Language in Vision-Language-Action Models

SALT is introduced, a Semantically ALigned action Tokenizer that augments a VQ-VAE-style tokenizer with an auxiliary objective requiring a frozen vision-language model to recover the episode instruction from quantized action latents to substantially improve language-conditioned control.
