视觉障碍学生（维斯）无法获得视觉信息，这使得他们的学习过程变得复杂。本文讨论了孟加拉国维斯的总体情况，并确定了他们在接受教育方面面临的主要挑战。孟加拉国的盲人学生采用盲文系统接受教育。然而，缺乏基于盲文的教育资源和技术解决方案，使得维斯的学习过程冗长而复杂。作为一个发展中国家，孟加拉国负担不起昂贵的维斯盲文相关技术工具。因此，一个基于移动的手机的盲文应用程序，“mBRAILLE”，为Android平台的设计，以提供一个简单的盲文学习技术，维斯在孟加拉国。建议的设计由残疾学生辅助技术专家和盲文高级学习者进行评估。该应用程序旨在为维斯提供孟加拉语和英语盲文学习平台。在本文中，我们描绘了迭代（参与式）设计的应用程序沿着与5个盲人科目，1视力和2盲专家的初步评估。结果显示，所有受访者对该设计的总体满意度为4.53（满分5分），表明我们的设计已经为下一步的开发做好了准备。
Visually impaired students (VIS) are unable to get visual information, which has made their learning process complicated. This paper discusses the overall situation of VIS in Bangladesh and identifies major challenges that they are facing in getting education. The Braille system is followed to educate blind students in Bangladesh. However, lack of Braille based educational resources and technological solutions have made the learning process lengthy and complicated for VIS. As a developing country, Bangladesh cannot afford for the costly Braille related technological tools for VIS. Therefore, a mobile phone based Braille application, “mBRAILLE”, for Android platform is designed to provide an easy Braille learning technology for VIS in Bangladesh. The proposed design is evaluated by experts in assistive technology for students with disabilities, and advanced learners of Braille. The application aims to provide a Bangla and English Braille learning platform for VIS. In this paper, we depict iterative (participatory) design of the application along with a preliminary evaluation with 5 blind subjects, and 1 sighted and 2 blind experts. The results show that the design scored an overall satisfaction level of 4.53 out of 5 by all respondents, indicating that our design is ready for the next step of development.
