在本文中，我们提出了一些适应地理信息系统（GIS）组件中使用的GPS导航系统。在我们的设计过程中，我们采用了以用户为中心的设计方法，与最终用户和方向和移动性（O&M）教师合作。提出了一种数据库方案来集成用户和O&M讲师提出的主要类。此外，还实施了一些分析工具，并将其集成到GIS中。这种适应的GIS可以改善现有和未来EOA的指导过程。第一个实施方案的适应性指导过程，允许更好地表示周围环境提供作为说明，这种适应性的GIS。这项工作是NAVIG系统（人工视觉和全球导航卫星系统辅助导航）的一部分，该系统是一种辅助装置，其目的是通过提高定向和移动能力来改善视力障碍者的生活质量。
In this paper, we propose some adaptation to Geographical Infor-mation System (GIS) components used in GPS based navigation system. In our design process, we adopted a user-centered design approach in collaboration with final users and Orientation and Mobility (O&M) instructors. A database scheme is presented to integrate the principal classes proposed by users and O&M instructors. In addition, some analytical tools are also implemented and integrated in the GIS. This adapted GIS can improve the guidance process of existing and future EOAs. A first implementation of an adapted guidance process allowing a better representation of the surroundings is provided as an illustration of this adapted GIS. This work is part of the NAVIG system (Navigation Assisted by Artificial VIsion and GNSS), an assistive device, whose aim is to improve the Quality of Life of Visually Impaired (VI) persons via increased orientation and mobility capabilities.
