| 摘要: |
| 目的 主要讨论在公共空间环境中有视觉障碍的人群，对导向系统信息的需求重点和导向信息密度分析。方法 结合视障人群的视听及运动规律，以视障人群与正常视力人群功能差异与功能联系性为基础，从信息节点、信息层级分布、信息表现形式等方面，对导向系统进行定向分析。结论 针对视障群体的导向系统要做到以功能性为首要要求，既要满足接受信息简单快速，又要保证系统完整统一，以视障人群的视角来衡量和定位导向系统中的信息点，为有视力障碍的群体提供简单而完整地导向的作用。 |

| Abstract: |
| It aims to discuss the demand for guide signage system in the public space environment from the visual impaired people and the analysis of the information density. Combined with the audio-visual and moving laws of visually impaired people, based on the functional difference between visual impaired people and normal eyesight people and function connection, it directionally analyzes the guide signage system from the aspect of information nodes, the distribution of information hierarchy and information representation. The guide signage system for the visual impaired people to do to function as the primary requirement, not only to meet the simple and rapid acceptance the information, but also to ensure the integrity of the system. The information points are measured and located by visually impaired people's perspective and positioning in the guide signage system and to provide the simple and complete guide for the visual impaired people. |
