TL;DR
J-ORA introduces a rich attribute-annotated multimodal dataset to advance Japanese robot perception across object identification, reference resolution, and action prediction. By extending J-CRe3 with a detailed attribute template and dynamic scene annotations, it enables end-to-end multimodal perception models trained on egocentric, indoor data. Experimental results show attribute information improves performance, but there remains a gap between proprietary and open VLMs and affordance understanding varies by object. The work provides a scalable framework for semi-automatic dataset expansion in dynamic, real-world environments.
Abstract
We introduce J-ORA, a novel multimodal dataset that bridges the gap in robot perception by providing detailed object attribute annotations within Japanese human-robot dialogue scenarios. J-ORA is designed to support three critical perception tasks, object identification, reference resolution, and next-action prediction, by leveraging a comprehensive template of attributes (e.g., category, color, shape, size, material, and spatial relations). Extensive evaluations with both proprietary and open-source Vision Language Models (VLMs) reveal that incorporating detailed object attributes substantially improves multimodal perception performance compared to without object attributes. Despite the improvement, we find that there still exists a gap between proprietary and open-source VLMs. In addition, our analysis of object affordances demonstrates varying abilities in understanding object functionality and contextual relationships across different VLMs. These findings underscore the importance of rich, context-sensitive attribute annotations in advancing robot perception in dynamic environments.
