The smartphone has become an indispensable travel companion for contemporary tourists. However, how smartphone use during the trip changes the travel context and related travel decision-making is still unclear. By tracing the in-situ decision-making processes in a real-world setting, this empirical study develops a deep understanding of the role of smartphones in shaping the physical and social contexts within which on-site decisions are made. The findings suggest that smartphones create a complex phygital-social context that triggers and supports the development of new travel plans, re-examination of pre-trip plans, and cancellation of pre-trip plans. Interactions with the smartphone-mediated context facilitate efficient decision-making and enable experience optimization. This study provides implications for decision-making theory in tourism and offers practical implications for destination marketing and management.

智能手机已成为当代游客不可或缺的旅行伴侣。然而，旅行期间智能手机的使用如何改变旅行环境和相关旅行决策仍不清楚。通过追踪真实世界环境中的现场决策过程，这项实证研究深入了解了智能手机在塑造现场决策的物理和社会环境中的作用。研究结果表明，智能手机创造了一个复杂的物理社会环境，可以触发和支持新旅行计划的制定、旅行前计划的重新检查以及旅行前计划的取消。与智能手机介导的上下文的交互促进了高效的决策并实现了体验优化。
