为了支持行人在定向和寻路任务与移动的设备适当的可视化他们的位置，其周围环境，和背景信息是必要的。在本文中，我们提出了两个互补的概念，结合现实的意见和位置的具体信息，可以实现与当前一代的PDA和下一代手机。第一种方法是利用城市中沿着每条道路上的视频剪辑，并通过位置信息进行增强。它示出了如何由视频和文本信息组成的多媒体剪辑可以存储和传输使用SMIL标准从W3C联盟。第二种方法通过在城市中的每个决策点（即街道路口）拍摄的全景图像中覆盖虚拟路标来支持导航。我们认为，位置和方向同步呈现（先前记录的）现实的意见，结合位置特定的信息是一个直观的补充，以地图为基础的可视化，一方面，侵入性和资源需求比增强现实系统与头戴式显示器的另一方面。
In order to support pedestrians in the tasks of orientation and wayfinding with mobile devices appropriate visualizations of their location, its surrounding, and background information are needed. In this paper we present two complementary concepts for the combination of realistic views and location specific information that can be implemented with current generation PDAs and next generation cellular phones. The first employs video clips that were taken along every path in a city which are augmented by location information. It is shown how multimedia clips consisting of videos and textual information can be stored and transferred using the SMIL standard from the W3C consortium. The second approach supports navigation by the overlay of virtual signposts in panoramic images taken for every decision point, i.e. street junctions, in a city. We argue that the location- and orientation-synchronized presentation of (previously recorded) realistic views in combination with location specific information is an intuitive complement to map based visualization on the one hand and less invasive and resource demanding than augmented reality systems with head mounted displays on the other hand.
