Blind color user interface requirements: A UMI specification

Color blindness, or color vision deficiency, is an inability to see the difference between certain colors. Men are more likely to be born with color blindness. Most people with color blindness can’t distinguish between certain shades of red and green. Less commonly, people with color blindness can’t distinguish between shades of blue and yellow. For that it’s a significant barrier to effective computer use. Several research works dealing with blind color user interfaces are currently conducted. However, requirements engineering for such interfaces is still missing. The work presented in this paper is part of an automated blind color user interface generation project which explores suitable input requirements document notations, simplifies the generating process, and outputs generated color blind user interface. It aims to define functional and nonfunctional requirements for powerful color-blind user interface and their UML specification. Thus, different recent techniques that deal with these interfaces are selected according to their relevance and up to date, then they are analyzed, the lack of requirements engineering for these interfaces was stated, and a solution is proposed. It consists of requirements elicitation and specification with UML notations. A case study evaluating the proposed approach is presented. The obtained results confirm the power and positive impact of such requirements engineering on research in this domain.
