| 摘 要： | 相对空间比绝对空间更易于被人理解。行人导航本质是以相对于人的导航环境视觉与空间等相对语义来动态引导行人的过程，即相对导航。目前，GIS导航理论以绝对定位与空间建模为基础，没有充分理解人对相对语义的认知差异，缺乏基于相对语义的导航理论模型。首先，总结了以绝对空间定位与表达为基础的行人导航研究，提出了相对空间感知的行人导航研究新方向。然后，剖析了相对导航研究的理论研究需求，如:行人相对导航数据采集与建模、行人导航环境相对语义的提取、行人导航行为的自动感知分析、行人导航的多感官交互机制、行人导航路径选择与确认机制等。最后，展望了未来行人导航研究与重要创新的3个阶段。

| Abstract: | Relative space is easier to be understood and used in navigation service by pedestrians. The basic characteristic of pedestrian navigation process is the relative space-based guidance by visual and spatial semantics within outdoor and indoor environment. It could be called relative pedestrian navigation. Current pedestrian navigation theory and technique are built upon the locating and modeling within the absolute space. It could not understand the difference of recognition ability of different pedestrians, especially on the relative visual and spatial semantics. The research community of pedestrian navigation doesn't have a relative space-based pedestrian navigation theory framework and technology, which makes the pedestrian services not friendly. This paper reviews the related studies on pedestrian navigation, such as the outdoor/indoor positioning, data collecting and organizing, route planning and guiding. Then, this paper concludes the potential research problems of pedestrian navigation, for example, the relative data collecting and modeling, relative semantic attracting, pedestrian navigation behavior sensing, multisensory interaction, and route choice and confirming mechanism. Finally, this paper introduces a three-stage divisions for the future pedestrian navigation studies. |
