📝 摘要(中文)

语言引导的人类跟随是具身智能体的重要能力,但现有基准通常假设目标在情节开始时可见,这简化了问题并忽视了更现实的需求:智能体需要首先找到语言描述的目标,然后在动态环境中持续跟随该目标。为了解决这些局限性,本文提出了统一的具身寻觅与跟随基准(UESF-Bench),这是一个大规模且多样化的基准,要求智能体处理语义引导的探索、可靠的行为切换与恢复,以及延迟的身份定位。实验结果表明,所提出的SeekFollow-VLA框架在单人和多人环境中相较于基线有显著提升。

🔬 方法详解

问题定义:本文旨在解决现有基准在具身智能体寻觅与跟随任务中的局限性,特别是目标可见性假设带来的不现实性。现有方法通常将寻觅与跟随视为独立任务,缺乏统一的评估标准。

核心思路:提出的SeekFollow-VLA框架通过结合视觉、语言和动作,设计了任务驱动的路由机制,以实现寻觅与跟随之间的有效转换和建模。这样的设计能够更好地应对动态环境中的复杂性。

技术框架:整体架构包括三个主要模块:语义引导的探索模块、行为切换与恢复模块,以及延迟身份定位模块。智能体通过这些模块实现从目标寻觅到持续跟随的无缝过渡。

关键创新:最重要的技术创新在于将寻觅与跟随任务统一建模,提出了一个新的评估基准UESF-Bench,填补了现有研究的空白。与传统方法相比,SeekFollow-VLA能够更有效地处理复杂的动态环境。

关键设计:在网络结构上,采用了多模态融合技术,结合视觉特征和语言描述,设计了特定的损失函数以优化行为切换的准确性和稳定性。

🎯 应用场景

该研究的潜在应用领域包括智能家居、服务机器人和人机交互等场景。通过提升智能体在动态环境中的寻觅与跟随能力,能够显著改善用户体验和服务质量,具有广泛的实际价值和未来影响。

📄 摘要(原文)

Language-guided human following is an important capability for embodied agents, but existing benchmarks typically assume that the target person is visible at the start of an episode. This setting simplifies the problem and overlooks a more realistic requirement: an agent often needs to first find a language-described target and then persistently follow that target in a dynamic environment. While recent work has started to study human search, existing settings are typically evaluated in task-specific scenarios and often rely on stronger prior knowledge of the environment. Moreover, they usually treat searching and following as separate tasks and still lack a unified benchmark for systematic evaluation. To address these limitations, we introduce the Unified Embodied Seeking and Following Benchmark (UESF-Bench), a large-scale and diverse benchmark for embodied human seeking and following. The benchmark requires agents to handle semantic-guided exploration, reliable behavior switching and recovery, and delayed identity grounding. To this end, we propose SeekFollow-VLA, a vision-language-action framework with a task-driven routing mechanism for latent phase inference and transition modeling between seeking and following. Experimental results show that SeekFollow-VLA achieves clear improvements over both single-head and dual-head baselines across single-person and multi-person environments, establishing a baseline for unified embodied seek-and-follow.
