摘　　要：目的研究影响全盲用户使用导航软件的因素,并基于信息无障碍设计,提出具体的设计策略和服务系统架构,为导航软件进一步服务全盲用户提供借鉴。方法首先,提出信息无障碍设计中信息的等效替代、强固性、易用性及设计的通用性原则。其次,从生理、认知和行为习惯等方面分析全盲用户群特征,并通过实地访谈和观察实验的方法对全盲用户进行调查研究,构建人物角色模型,绘制用户旅程图,从而获知全盲用户使用导航软件的痛点和机会点。结论研究表明当前导航软件的无障碍服务水平有待提升,存在缺少盲道指引、无障碍物提示、目的地定位不准确等问题,因此,在增加盲道指引,利用听觉感官给予交互反馈,提供实时路况这3个具体功能点的基础上,构建信息无障碍的服务系统架构。This paper aims to study the factors influencing the use of navigation software for all blind users,and put forward specific design strategies and service system architecture based on the principle of information accessibility design, to provide reference for better serving full blind users with navigation software.Firstly,it proposed principles of equivalent substitution,robustness,easy operation,and universal design in information accessibility design.Second,it analyzed the characteristics of full blind users from physiology,cognition,and behavioral habits,and conducted interviews and observation experiments through the field.The method conducted research on full blind users,built character models,and drew user journey maps to learn about pain points and opportunities for full blind users to use navigation software.The research shows that the accessibility service level of the current navigation software needs to be improved. There is a lack of blind channel guidance,obstacle promp and accurate destination location.Therefore,on the basis of increasing the blind channel active guidance,using the auditory sensory interaction feedback and providing real time road conditions,the three specific functions of the user are presented to build the architecture of the information accessibility service system.
