Demonstrating PANDALens: Enhancing Daily Activity Documentation with AI-assisted In-Context Writing on OHMD

We introduce PANDALens, a Proactive AI Narrative Documentation Assistant built on an Optical See-Through Head-Mounted Display that transforms the in-context writing tool into an intelligent companion during daily activities. PANDALens observes multimodal contextual information from user behaviors and the environment to detect interesting moments and elicit contemplation. It also employs Large Language Models to transform such multimodal information into coherent narratives with significantly reduced user effort. PANDALens was iteratively designed through a formative study identifying the user requirements. We verify its utility in a real-world travel scenario in improving writing quality and travel enjoyment while minimizing user effort.
