Poster: Enabling Agent-centric Interaction on Smartphones with LLM-based UI Reassembling

In this poster, we introduce a novel dynamic user interface (UI) specifically designed for mobile devices powered by large language models (LLMs) agents. The advent of LLMs has led to a surge in deploying LLM-based agents on personal and Internet of Things (IoT) devices, with the aim of facilitating various daily tasks through device manipulation. However, this integration poses a significant challenge: how to intelligently and flexibly select and present information both during and after the execution of tasks, ensuring users are well-informed about the operations and can access the desired results conveniently. To address this challenge, we propose a UI reassembling method. This method allows for analyzing and strategically combining different mobile applications and their UI components, enabling the dynamic construction and adjustment of UIs tailored to user needs. Our prototype exhibits promising performance, with the UI selection module achieving an F1 score of 0.74. This innovative approach opens up exciting possibilities of new user-device interaction paradigm, leveraging the capabilities of LLMs to enhance the user experience in handling mobile and IoT devices.
