Abstract

Purpose The study aims to promote independent mobility for persons with visual impairment or legal blindness (VIB) by developing a Web-based wayfinding application using geographic information systems (GIS). While the literature mainly focuses on technical devices presenting results for wayfinding, a lack of integration of user needs is identified. The inclusive, participative developed application offers step-by-step directions for pre-trip planning through an accessible user interface. Design/methodology/approach The paper presents a semi-automated approach to extract a pedestrian routing network data set based on open government data and field survey. User profiles calculate different routes using a weighting scheme for landmarks, orientation hints, infrastructure of crossings and sidewalks. The adoption of ArcGIS Web AppBuilder widgets allows access of the user interface additionally through keyboard-only navigation and therefore screen-reader capability. Findings GIS offers a powerful tool to design network analysis for persons with VIB. The routing algorithm accesses different user profiles, returning individualized turn-by-turn directions. The complex set of attributes, including shorelines, landmarks and barriers, can be integrated by semi-automated processes. Practical implications The paper illustrates the benefit of GIS applications for wayfinding of persons with VIB to raise self-determination and independence. Originality/value A ubiquitous pedestrian sidewalk network for a medium-size city comprises a novelty, as research has mainly focused on small areas. The integration of shorelines next to a various number of hints, landmarks and potential barriers through semi-automated processes allows reproducibility and transferability of the model to other cities.

使用GIS实现VIB患者的独立移动

目的本研究旨在通过使用地理信息系统（GIS）开发基于Web的寻路应用程序，促进视障或法盲患者的独立行动能力。虽然文献主要集中在提供寻路结果的技术设备上，但发现缺乏对用户需求的整合。包容性、参与性开发的应用程序通过可访问的用户界面为旅行前规划提供了循序渐进的指导。设计/方法论/方法本文提出了一种基于开放政府数据和实地调查的半自动化方法来提取步行路线网络数据集。用户配置文件使用地标、方向提示、十字路口和人行道的基础设施的加权方案来计算不同的路线。ArcGIS Web AppBuilder小部件的采用允许通过仅键盘导航和屏幕阅读器功能访问用户界面。FindingsGIS为VIB患者提供了一个强大的网络分析设计工具。路由算法访问不同的用户配置文件，返回个性化的逐转弯方向。包括海岸线、地标和障碍物在内的一组复杂属性可以通过半自动化流程进行集成。实际意义本文阐述了GIS应用于VIB患者寻路以提高自主性和独立性的好处。独创性/价值中等城市普遍存在的人行道网络是一种新颖性，因为研究主要集中在小区域。通过半自动化过程，将海岸线与各种提示、地标和潜在障碍物相结合，可以使模型具有可复制性和可转移性。

期刊介绍： The Journal of Enabling Technologies (JET) seeks to provide a strong, insightful, international, and multi-disciplinary evidence-base in health, social care, and education. This focus is applied to how technologies can be enabling for children, young people and adults in varied and different aspects of their lives. The focus remains firmly on reporting innovations around how technologies are used and evaluated in practice, and the impact that they have on the people using them. In addition, the journal has a keen focus on drawing out practical implications for users and how/why technology may have a positive impact. This includes messages for users, practitioners, researchers, stakeholders and caregivers (in the broadest sense). The impact of research in this arena is vital and therefore we are committed to publishing work that helps draw this out; thus providing implications for practice. JET aims to raise awareness of available and developing technologies and their uses in health, social care and education for a wide and varied readership. The areas in which technologies can be enabling for the scope of JET include, but are not limited to: Communication and interaction, Learning, Independence and autonomy, Identity and culture, Safety, Health, Care and support, Wellbeing, Quality of life, Access to services.
