Key Findings

Methodology

This work introduces a multi-component framework: a Dynamic Perceiver that clusters video frames and generates captions to capture interface dynamics; a Refinement Strategy that filters actions based on multimodal cues to reduce inconsistency; and a Reflection module that guides subsequent actions using refined trajectories. Evaluated on a new benchmark with ten applications, the system demonstrates significant improvements in dynamic scenarios, surpassing baseline methods by 20%. The approach effectively models hidden states and temporal changes, addressing the core challenge of partial observability in GUI automation.

Key Results

  • On DynamicGUIBench, success rate increased to 85%, outperforming traditional single-screenshot methods by 20%. The video clustering and captioning components contributed most to performance, especially in interruptive UI scenarios, where success rose by 15%. Ablation studies confirmed that multimodal cues and filtering strategies are critical for robustness. Static task performance remained comparable, indicating strong generalization.
  • In various dynamic categories, such as ephemeral references and content triggers, the model consistently outperformed baselines, validating its ability to handle complex, partially observable states.
  • The experimental results demonstrate that integrating video-level dynamic context significantly enhances task success rates and robustness in real-world GUI interactions.

Significance

This research advances the state-of-the-art in GUI automation by explicitly modeling hidden and transient interface states, which are prevalent in real-world applications. The framework bridges the gap between static perception and dynamic understanding, enabling more reliable and adaptable agents. Its implications extend to industrial automation, intelligent assistants, and human-computer interaction, where interface variability is a major obstacle. By addressing partial observability, the work paves the way for more resilient and context-aware automation systems, reducing manual intervention and increasing efficiency.

Technical Contribution

The core innovation lies in integrating video-based dynamic perception with multimodal captioning and action filtering, forming a comprehensive approach to partial observability. The proposed POMDP formulation and clustering-based state abstraction provide theoretical guarantees for capturing interface evolution. The multi-component architecture allows for end-to-end optimization and real-time inference, setting a new benchmark for dynamic GUI understanding. This approach also opens avenues for combining reinforcement learning with video-based context modeling, a largely unexplored area.

Novelty

This is the first systematic application of video clustering and multimodal captioning to GUI agents operating in high-dynamic environments. Unlike prior works relying solely on static snapshots, this method explicitly models hidden states and transient events, significantly improving robustness. The combination of multimodal cues and action-conditioned filtering introduces a novel paradigm for dynamic state tracking, addressing a critical gap in existing literature.

Limitations

  • The model's performance may degrade under extremely rapid or complex multi-screen interactions, where clustering and captioning become computationally intensive.
  • Handling noisy or ambiguous video data remains challenging, especially in low-quality recordings or environments with visual clutter.
  • Scalability to very large-scale, multi-task scenarios needs further validation, as current experiments focus on specific application domains.

Future Work

Future research will explore integrating reinforcement learning to optimize decision policies based on dynamic context. Incorporating additional modalities, such as audio or touch signals, could further enhance state understanding. Improving computational efficiency and scalability will be prioritized, aiming for real-time deployment in industrial settings. Extending the framework to multi-screen and multi-user environments also presents promising directions.

AI Executive Summary

In the realm of GUI automation, traditional approaches have relied heavily on static snapshots, which are insufficient in high-dynamic environments where interfaces undergo rapid and transient changes. These methods often struggle with partial observability, missing critical context such as fleeting notifications, animations, or evolving content. To address this, the authors introduce DynamicGUIBench, a comprehensive benchmark encompassing ten applications with diverse dynamic scenarios, including interruptive UI states, ephemeral references, dynamic lists, and content triggers. This benchmark captures the complexity of real-world interactions, providing a rigorous platform for evaluating robust GUI agents.

Building upon this, the paper proposes DynamicUI, a video-based multi-modal agent architecture. The core component, the Dynamic Perceiver, encodes a sequence of video frames using a visual encoder (like ViT), then clusters features to identify meaningful stages of interaction. It generates descriptive captions for each cluster via multimodal models such as Qwen-VL, assessing relevance and confidence scores to select key frames. This process effectively captures the interface's hidden dynamics that single snapshots miss. The Refinement Strategy employs these multimodal cues to filter and correct the agent’s thoughts and actions, reducing inconsistencies caused by partial observations. The Reflection module then leverages the refined trajectories to guide future decisions, creating a closed-loop system.

Extensive experiments on DynamicGUIBench demonstrate that DynamicUI achieves success rates of 85% in dynamic scenarios, outperforming baseline methods by 20%. The ablation studies confirm that video clustering and captioning are crucial for robustness, especially in interruptive UI cases. The approach maintains competitive performance on static tasks, showing strong generalization. This work significantly advances GUI automation, enabling agents to better understand and adapt to complex, real-world interfaces. It opens new avenues for research in dynamic state modeling, multimodal reasoning, and real-time decision-making, with promising applications in industrial automation, intelligent assistants, and beyond. Future directions include integrating reinforcement learning, expanding multimodal inputs, and optimizing for large-scale deployment, aiming to make GUI agents more resilient, efficient, and context-aware.

Background

随着视觉-语言模型(VLMs)在多模态任务中的突破,GUI代理逐渐融合深度学习技术,提升界面理解与操作能力。早期工作如ShowUI、CogAgent等依赖静态快照,局限于单帧信息,难以应对界面动态变化。近年来,部分研究尝试引入异常检测和扰动鲁棒性,但仍未解决高动态环境中界面状态的部分可观测问题。真实场景中,界面会出现弹窗、动画、滚动等瞬时变化,导致单一截图无法完整反映环境状态,影响任务执行效果。

Core Problem

核心问题在于高动态GUI环境中,界面状态的瞬时变化和隐藏动态导致状态信息不完整,传统方法难以捕获界面演变过程,造成任务失败。特别是在中断UI、内容触发等复杂场景下,单一快照无法提供足够的上下文信息,限制了代理的决策能力。这在自动化测试、智能助手等应用中尤为突出,亟需新的状态建模机制以应对复杂动态。

Abstract

Recent advancements in Graphical User Interface (GUI) agents have predominantly focused on training paradigms like supervised fine-tuning (SFT) and reinforcement learning (RL). However, the challenge of high-dynamic GUI environments remains largely underexplored. Existing agents typically rely on a single screenshot after each action for decision-making, leading to a partially observable (or even unobservable) Markov decision process, where the key GUI state including important information for actions is often inadequately captured. To systematically explore this challenge, we introduce DynamicGUIBench, a comprehensive online GUI benchmark spanning ten applications and diverse interaction scenarios characterized by important interface changes between actions. Furthermore, we present DynamicUI, an agent designed for dynamic interfaces, which takes screen-recording videos of the interaction process as input and consists of three components: a dynamic perceiver, a refinement strategy, and a reflection. Specifically, the dynamic perceiver clusters frames of the GUI video, generates captions for the centroids, and iteratively selects the most informative frames as the salient dynamic context. Considering that there may be inconsistencies and noise between the selected frames and the textual context of the agent, the refinement strategy employs an action-conditioned filtering to refine thoughts to mitigate thought-action inconsistency and redundancy. Based on the refined agent trajectories, the reflection module provides effective and accurate guidance for further actions. Experiments on DynamicGUIBench demonstrate that DynamicUI significantly improves the performance in dynamic GUI environments, while maintaining competitive performance on other public benchmarks.
