Usability and accessibility issues are common causes why software fails to meet user requirements. However, requirements engineers still focus on functional requirements and might ignore to also elicit system usability and accessibility requirements. Improving the usability and accessibility of a system in a later development stage is costly and time consuming.
Conference proceedings front matter may contain various advertisements, welcome messages, committee or program information, and other miscellaneous conference information. This may in some cases also include the cover art, table of contents, copyright statements, title-page or half title-pages, blank pages, venue maps or other general information relating to the conference that was part of the original...
The aim of our research is the integration of personas into the requirements engineering process. The persona technique enables a better understanding of users' characteristics and thereby highlights the user needs in software development. We identify fundamental supporting purposes of personas for the requirements engineering process and match these benefits to the activities of the process.
Functional usability features like Undo or Auto-Save can greatly add to the usability of interactive software systems. This paper presents a pragmatic approach to considering usability features as “first-class citizens” during early phases of software development, in particular during requirements analysis and definition. A catalog of usability patterns is used to describe proven and reusable solutions...
Product development processes and best practices have come a long way in the last decade through continuous evolutions of new lifecycle and process models. Development models such as the waterfall model, spiral model, rational unified process, agile and many others have looked at efficiency of the development processes. These approaches have helped practitioners improve immensely on the efficiency...
In recent years the explosive growth of smartphones and the evolution of mobile communication networks have certainly revolutionized the way how people communicate and access information. This revolution is even more tangible in developing countries where mobile devices are becoming the preferred way to access services for their daily activities. In this context, the development of mobile applications...
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...
Patent law still relies on textual argumentation when determining inventiveness, i.e. (non)obviousness, of inventions over prior state-of-the-art, i.e. published knowledge, in patent disputes. The objective of this research is to support an industrial partner to identify usability issues supporting requirements engineering when introducing the Facts Screening and Transforming Processor (FSTP), a systematic,...
Popularity and affordability of mobile computers, especially tablets and smart phones, is considerably rising, providing an access capability for different user groups to various ICT services. Nevertheless, software solutions and hardware devices often seem not suitable enough for some target groups, like people with complex communication needs. In order to gain understanding of the challenges for...
