基于GPS定位的步行导航用户分心研究

Studying User Distractions with GPS Based Pedestrian Navigation System

【目的】分析定位准确度不一样的情况下用户分心的情况,并提出有效减少用户分心的建议与策略。【方法】采用基于真实场景的模拟实验方式,通过设置对照组,使用描述性统计方法和差异性检验来分析和比较在是否开启GPS定位的两种情况下,用户分心次数和时长的情况。【结果】研究结果表明,开启GPS定位的情况下,用户对地图路线依赖度会明显增加,导致用户更加关注GPS定位点的指向,增加用户中途停留行为,但是会减少操作地图的行为。【局限】实验设计中无法排除实验者个体因素对实验结果的影响,并且可参考的理论依据较少。【结论】步行导航中出现分心会增加步行时长,降低满意度,增加错误率。为了减少用户分心,不仅用户需要减少对手机地图规划的路线的依赖度,地图导航系统应该提供具体化、全面化导航信息。

[Objective] The purpose of this paper is to reduce user distractions effectively by analyzing their reactions to various positioning accuracy of a pedestrian navigation system. [Methods] First, we collected users＇ behavior data from the simulation and controlled experiments. Then, we compared the user distraction frequencies and durations with descriptive statistics and significance tests. [Results] We found that users paid more attention to the orientation of the GPS, which increased the number of stopovers and reduced interactions with the APP. [Limitations] We could not exclude the influence of the individual factors on the results and few previous studies discussed the theoretical foundation of our study. [Conclusions] To reduce distractions, pedestrians should decrease their reliance on the navigation system, while the latter needs to provide more specific and comprehensive information.
