由模型翻译 · 术语统一 · 请对照原文核对关键结论多模态 AI 智能体正日益自动化涉及在线网页执行的复杂真实世界工作流。然而,当前的网页智能体基准存在一个关键局限:它们完全聚焦于基于网页的交互与感知,缺乏对用户真实物理环境的接地。这一局限阻碍了对关键场景的评估,例如智能体必须利用第一人称视觉感知(如通过 AR 眼镜)识别用户周围物体,然后在线完成相关任务(如购买与该物体相关的商品)。为填补这一空白,我们提出 Ego2Web,首个旨在连接第一人称视频感知与网页智能体执行的基准。Ego2Web 将真实世界第一人称视频记录与需要视觉理解、网页任务规划及在线环境交互才能成功完成的网页任务配对。我们利用自动数据生成流程结合人工验证与精炼,精心构建了跨多种任务类型(包括电子商务、媒体检索、知识查询等)的高质量视频-任务对。为促进对本基准准确且可扩展的评估,我们还开发了一种新颖的 LLM-as-a-Judge 自动评估方法 Ego2WebJudge,其与人类判断的一致性达到约 84%,显著高于现有评估方法。在 Ego2Web 基准上对多种最先进智能体的实验表明,它们的性能仍然较弱,在所有任务类别中均有巨大提升空间。我们还对任务设计进行了全面的消融实验,强调了准确视频理解在 Ego2Web 中的必要性以及当前智能体的局限性。我们希望 Ego2Web 能成为开发能够在物理与数字世界间无缝看见、理解并行动的有能力 AI 助手的关键新资源。

Multimodal AI agents are increasingly automating complex real-world workflows that involve online web execution. However, current web-agent benchmarks suffer from a critical limitation: they focus entirely on web-based interaction and perception, lacking grounding in the user's real-world physical surroundings. This limitation prevents evaluation in crucial scenarios, such as when an agent must use egocentric visual perception (e.g., via AR glasses) to recognize an object in the user's surroundings and then complete a related task online (e.g., making a purchase related to that object). To address this gap, we introduce Ego2Web, the first benchmark designed to bridge egocentric video perception and web agent execution. Ego2Web pairs real-world first-person video recordings with web tasks that require visual understanding, web task planning, and interaction in an online environment for successful completion. We utilize an automatic data-generation pipeline combined with human verification and refinement to curate well- constructed, high-quality video-task pairs across diverse task types, including e-commerce, media retrieval, knowledge lookup, etc. To facilitate accurate and scalable evaluation for our benchmark, we also develop a novel LLM-as-a-Judge automatic evaluation method, Ego2WebJudge, which achieves approximately 84% agreement with human judgment, substantially higher than existing evaluation methods. Experiments with diverse SoTA agents on our Ego2Web benchmark show that their performance is still weak, with substantial headroom across all task categories. We also conduct a comprehensive ablation study on task design, highlighting the necessity of accurate video understanding in Ego2Web and the limitations of current agents. We hope Ego2Web can be a critical new resource for developing capable AI assistants that can seamlessly see, understand, and act across the physical and digital worlds.
