Requirements gathering for assistive technology that includes low vision and sighted users

Abstract

Accessibility often concerns compatibility with third-party software in order to meet the needs of users who are disabled. The AccessLecture project seeks to transform the Apple iPad into a tool to make Math and Science class more accessible to visually impaired students. Accessing lecture material during lecture is a challenge to low vision students, in terms of the limited options that can be costly or can allow access only upon the completion of the lecture. This paper presents the techniques used to help the team gather the needs and tasks of math/science instructors and visually impaired students. The analysis of the environment, user groups and the tasks related to the course lecture were modeled in order to ascertain domain knowledge and to specify the system's requirements.
