在本文中，我们提出了一种利用沉浸式虚拟环境结合移动眼动追踪系统来评估导航系统的新方法。在虚拟环境中捕捉位置、运动、视锥体和凝视的精确测量。它们被应用于将注意力地图投影到虚拟3D环境中，以可视化环境中的注视以及物体被注视的时间。为了证明该方法的适用性，我们进行了一个有24名参与者的实验，评估一个大型公共基础设施的引导系统。结果表明，我们的方法允许创建注意力地图，以及基于眼动追踪识别感兴趣的对象。
In this article, we present a novel method for evaluating guidance systems using an immersive virtual environment in combination with a mobile eye tracking system. Accurate measurements of position, locomotion, viewing frustum, and gaze are captured in the virtual environment. They are applied to the projection of an attention map onto the virtual 3D environment for visualizing the fixation in the environment as well as the amount of time objects were fixated. To demonstrate the method's applicability, we conducted an experiment with 24 participants evaluating a guidance system of a large public infrastructure. The results show that our method allows for the creation of attention maps as well as for the identification of objects of interest based on eye tracking.
