移动地图交互中的步行路线规划情境研究

Route Planning in Pedestrian-Map APP Interactions

【目的】分析不同情境因素对用户步行路线规划的影响,构建用户路线规划的情境模型。【方法】邀请30名用户完成室外步行导航实验,对用户路线规划的情境和行为进行Spearman相关性分析和多元线性回归分析。【结果】初始规划阶段,目的地选择次数越多,用户搜索时长越长;对估计时间在意程度越高,对路线的浏览时长越长。重新规划阶段,不同性别和年龄的用户其主观时间压力不同;任务困难度越高时其操作次数反而会减少。【局限】数据处理存在一定的主观性;实验中其他因素给用户的心理和行为产生潜在影响,可能会对实验结果造成一定的干扰。【结论】步行路线规划情境模型更关注行为因素,揭示初始路线规划和重新规划路线的各个情境因素的关系,为移动地图开发者提供参考价值。

[Objective] This paper constructs a model for route planning based on the impacts of different contexts on pedestrian＇s walking behaviors. [Methods] First, we collected data from 30 participants of an outdoor pedestrian navigation experiment. Then, we analyzed the ties between contexts and users＇ behaviors with correlation and regression tests. [ResuLts] At the initial planning stage, more destinations chosen by the pedestrians meant longer searching time, while more users＇ attention to the estimated time led to longer browsing time. User＇s subjective time pressure, system location and destination choice also affected their attention to estimated time. In the re-planning stage, different genders and ages had different subjective time pressures on the users. The more difficult tasks generated fewer operations. [Limitations] There were some subjective issues with the data processing. The changing of user＇s psychology and behaviors may also influence the results. [Conclusions] The proposed model focuses on the user factors and reveals the relationship among the contexts of the initial plannings and the re-routings, which provide valuable information to the mobile map developers.
