AI 中文总结
本研究通过访谈旅行者和代理人，揭示约束与偏好在旅行规划中的动态作用，识别出11种关键行动，并为AI规划工具提出设计启发，以支持人机协作应对规划的流动性与偶然性。
AI 中文摘要
规划是一项常见但复杂的活动，它受到需满足的约束和需平衡的偏好的塑造。旅行规划既是一种日常活动，也是评估智能系统的常用基准，为考察约束和偏好如何出现及演变提供了丰富的情境。尽管近期的人工智能系统在生成个性化行程方面取得了显著成果，但它们往往假设用户能够事先明确表达稳定的目标。为了理解现实世界中的规划如何展开，我们进行了一项由两部分组成的访谈研究：一部分访谈了八位旅行者，回顾他们的规划经验；另一部分访谈了九位旅行代理人，分享专业实践。我们追踪了约束和偏好在整个规划过程中被呈现、细化及协调的动态，并识别出围绕约束和偏好的11种行动，这些行动塑造了规划过程。我们为规划工具提供了设计启发式，以更好地支持人机协作行动，从而适应规划中流动且偶然的特性。
英文摘要
Planning is a common yet complex activity shaped by constraints to satisfy and preferences to balance. Travel planning, as both an everyday activity and a frequent benchmark for evaluating intelligent systems, offers a rich context for examining how constraints and preferences emerge and evolve. While recent AI systems have achieved impressive results in generating personalized itineraries, they often assume that users can articulate stable goals upfront. To understand how real-world planning unfolds, we conducted a two-part interview study: one with eight travelers reflecting on their planning experiences, and one with nine travel agents sharing professional practices. We trace the dynamics of constraints and preferences as they are surfaced, refined, and coordinated throughout the planning process, and identified 11 actions revolving around constraints and preferences, which shaped the planning process. We offer design heuristics for planning tools that better support human-AI collaborative actions to support the fluid, contingent nature of planning.
