ActivityNarrated: An Open-Ended Narrative Paradigm for Wearable Human Activity Understanding
arXiv:2604.00767v2 Announce Type: replace Abstract: Wearable human activity recognition (HAR) has made steady progress, yet much of this progress remains grounded in fixed-window, closed-set classification benchmarks. This formulation is poorly matched to everyday behavior, where activities are open-ended, unscripted, personalized, variable in duration, and often compositional. To address this mismatch, we introduce ActivityNarrated, an open-ended narrative paradigm for language-grounded wearable activity understanding. We formulate this setting as dense sensor signal captioning with a compreh
The proliferation of wearable sensors and advancements in large language models make it increasingly viable to develop more nuanced and human-centric approaches to activity recognition.
This research moves beyond constrained activity classification to open-ended, language-grounded understanding, which is crucial for the development of context-aware AI agents and personalized digital assistants.
The ability of AI to interpret complex, unscripted human activity from wearable data will transition from predefined categories to dynamic, narrative-driven understanding.
