用于盲人导航的GML空间数据建模方法研究

Study on GML spatial data modeling method for blind navigation

在世界范围内,盲人及视力障碍者数量巨大.由于盲人群体不能像其他正常人一样获取外界的视觉信息,这种情况给他们的正常生活与生产带来了困难,进而影响他们的心理活动,造成了他们自卑冷漠的性格.这种情况他们需要一种既安全有效又廉价的方案,解决安全出行的问题.文章以盲人出行为研究对象,旨在通过以盲人的视角,分析盲人的心理特征、空间认知、行为特征,来构建GML导盲数据模型.文章在通道与功能单元思想的基础之上,以江西理工大学为例,构建了地理空间数据的应用模型以及实例数据,力图为导盲方法的研究提供参考.

The number of blind and visually impaired people in the world is huge. Because the blind can＇t capture the visual information from the outside world as the normal people, it causes trouble to their life and production, hence affecting their psychological activities and forming their characters of inferiority and apathy. Therefore, they need a safe, efficient and affordable solution to ensure their safe travel. This paper, taking blind people＇s travel as research object, aims to construct a GML blind guidance data model by analyzing the psychological characteristics, spatial cognition and behavioral characteristics of the blind from the perspective of blind people. Based on the idea of ＂Aisle-Functional Unit＂, this paper takes Jiangxi University of Science and Technology as an example to construct an application model of geospatial data and instance data with the purpose of providing references for the study of blind navigation methods.
