对于视障人士和盲人来说，在公共交通工具中寻找道路仍然是一个巨大的挑战。本评价研究是在研究项目Ways4All的背景下进行的，该项目旨在开发一个无障碍系统，为视障者和盲人使用公共交通提供便利。该研究旨在评估Ways4All开发的移动的应用程序的室内和室外导航模块。在一项有16名参与者的实地研究中，确定了系统的可用性和可访问性问题。此外，还调查了视力受损者和盲人是否希望除了系统提供的逐向指示之外，还能提前获得路线说明。数据分析表明，大多数视障人士和盲人喜欢在实际导航之前处理路线描述的可能性。根据用户反馈和出现的问题，为系统设计提出了建议。
Wayfinding in public transport is still a great challenge for visually impaired and blind people. The presented evaluation study was conducted in the context of the research project Ways4All, which aims to develop an accessible system to facilitate the use of public transport for visually impaired and blind people. The study aims to assess the indoor and outdoor navigation modules of the mobile application developed in Ways4All. In a field study with 16 participants usability and accessibility issues of the system were identified. Furthermore it was investigated whether visually impaired and blind people wish to have a route description in advance, besides the turn-by-turn instructions provided by the system. The data analysis shows that the majority of visually impaired and blind people like to have the possibility to process a route description before they actually navigate. On the basis of the user feedback and the occurring issues, recommendations for the system design were created.
