本文为德国慕尼黑工业大学(作者:Roar Gauslå Engell)的硕士论文,共57页。

 

本文对行人导航领域的贡献是双重的。首先,提出了四种利用增强现实技术实现室外行人导航路径可视化的设计方案。其次,它将这四种设计结合到一个导航系统中,并由该领域的用户研究进行评估。该系统是为微软全息透镜头戴式增强现实装置开发的。这四种视觉效果是:(1)地面上的红线;(2)朝运动方向飞行的鸟;(3)漂浮在路径上方的彩色立方体;(4)放置在决策点上指向预定运动方向的箭头。12名受试者完成了用户评价,并以问卷调查和简短访谈的形式提供了反馈。调查根据一系列参数对可视化效果进行评估:完成导航任务的时间、基于Likert的符合度以及关于可信度、路线可见性和使用系统的信心以及在导航过程中迷失的感觉。此外,还就这一经历进行了简短的采访。评估并没有产生一个统计上的优越设计,但是随后的访谈数据为每个可视化用例提供了建议。

 

The contribution of this thesis to thefield of pedestrian navigation is twofold. First, it presents four designs forvisualizing an outdoor pedestrian navigation path using Augmented Reality.Second, it incorporates these four designs in a navigation system that isevaluated by a user study in the field. The system is developed for a MicrosoftHoloLens head-mounted augmented reality device. The four visualizations are:(1) a red line on the ground; (2) a bird flying in the direction of movement;(3) colored cubes floating above the path, and (4) arrows pointing in theintended direction of movement, placed at decision points. Twelve test personscompleted the user evaluation and provided feedback in form of a questionnairesurvey and short interviews. The survey evaluated the visualizations accordingto a series of parameters: time to complete the navigation task, a Likertbasedscale of agreement with statements concerning the trustworthiness, visibilityof the route and confidence in using the system, as well as the feeling ofbeing lost during the navigation. Furthermore, a short interview about theexperience was conducted. The evaluation does not result in a statisticallysuperior design, but the subsequent interview data provides suggestions for usecases for each visualization.
