一句话总结

论文将时间分析黑暗模式（TADP）应用于德国麦当劳自助点餐机，揭示在同室内、跨系统与系统层面的时间分层黑暗模式，在时间压力下推动用户进行追加购买。

ABSTRACT

Self-ordering kiosks (SOKs) are widely deployed in fast food restaurants, transforming food ordering into digitally mediated, self-navigated interactions. While these systems enhance efficiency and average order value, they also create opportunities for manipulative interface design practices known as dark patterns. This paper presents a structured audit of the McDonald's self-ordering kiosk in Germany using the Temporal Analysis of Dark Patterns (TADP) framework. Through a scenario-based walkthrough simulating a time-pressured user, we reconstructed and analyzed 12 interface steps across intra-page, inter-page, and system levels. We identify recurring high-level strategies implemented through meso-level patterns such as adding steps, false hierarchy, bad defaults, hiding information, and pressured selling, and low-level patterns including visual prominence, confirmshaming, scarcity framing, feedforward ambiguity, emotional sensory manipulation, and partitioned pricing. Our findings demonstrate how these patterns accumulate across the interaction flow and may be amplified by the kiosk's linear task structure and physical context. These findings suggest that hybrid physical--digital consumer interfaces warrant closer scrutiny within emerging regulatory discussions on dark patterns.

研究动机与目标

• 通过考察自助点餐机在混合物理–数字环境中如何使用黑暗模式，来推动伦理设计。
• 使用TADP框架在12步点餐流程中绘制时间层级的操控映射。
• 识别在高速度互动的QSR点餐机中累积的中层与低层模式。

提出的方法

• 通过直接在德国的麦当劳自助点餐机进行就地数据收集。
• 在Omnigraffle中重建12步流程，并标注成本、依赖关系和黑暗模式实例。
• 以时间压力下用户先选取显眼/默认选项的情境来实现时序性操作。
• 将TADP本体应用于标注页面内、页面间和系统层面的黑暗模式。
• 分析模式在屏幕之间的重复出现，评估时间演变和累积效应。

实验结果

研究问题

• RQ1 德国麦当劳SOK 12步流中出现了哪些黑暗模式？
• RQ2 在时间压力下，页内、页间和系统层面的模式如何累积？
• RQ3 高层次策略（社会工程、界面干扰、阻碍、偷偷摸摸）如何形成为中层和低层模式？
• RQ4 与私有数字界面相比，物理-数字自助机环境如何放大这些模式？
• RQ5 对混合物理–数字订购环境的监管与伦理设计含义是什么？

主要发现

• 高层策略重复出现：在流程中存在社会工程、界面干扰、阻碍和偷偷摸摸等手法。
• 中层模式包括增加步骤、错误层级、错误默认、隐藏信息、被迫销售和选择过载。
• 低层模式包括视觉突出、确认羞辱、稀缺性框架、前馈模糊性、情感感官操控与分割定价。
• 时间性升级显示在12步路径中促销压力和货币金额的累计增加。
• 系统层面情境（公共排队、时间压力、线性任务流程）放大了对单独屏幕的操控效应。
