How personas support requirements engineering BIBAFull-Text 1-5
  Lydia Schneidewind; Stephan Hörold; Cindy Mayas; Heidi Krömker; Sascha Falke; Tony Pucklitsch
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.
Specifying usability features with patterns and templates BIBAFull-Text 6-11
  Holger Röder
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 and to support software engineers in selecting appropriate usability features for a system. To allow for a systematic consideration, usability features are specified in a use case-based software requirements specification using semiformal specification templates. The resulting extended specification defines where and how usability features shall be integrated in the system, thus facilitating subsequent development activities (e. g. software architecture design, implementation, and test).
Integrating requirements engineering and user experience design in product life cycle management BIBAFull-Text 12-17
  Anitha Pc; Beena Prabhu
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 and efficacy of the product development processes. However, product quality needs to be measured by parameters that go beyond the traditional criteria like performance, reliability, reusability etc. A product that has any interaction with the end user also needs to meet a fundamental requirement of being "user friendly". Development models such as JAD (Joint Application Development) have focused on making products user friendly. Apart from achieving the technical soundness in a product, the success of the product also largely depends on how well the product addresses the primary requirements of the user such as desirability, relevance and usability. Not meeting these requirements leads to bad user experience, which, in turn can actually lead to failure of the product. This paper discusses some of the misconceptions and myths that exist in the industry regarding Requirements Engineering (RE) and User Experience Design (UXD), and how user needs typically slip through the cracks under the name of "non functional requirements". The paper highlights the need for RE and UXD focus during the overall product development life cycle. In the concluding section an integrated framework for RE and UXD in the PLM process is presented.
User centered scenario based approach for developing mobile interfaces for social life networks BIBAFull-Text 18-24

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 in the areas of health, education, agriculture, and mobile banking become a crucial factor. Unfortunately, the development process presents non-trivial human and technological challenges. The goal of our research is to support people living in developing countries to improve their lives. In particular we focused our attention on assisting farmers from rural zones of Sri Lanka in optimizing their crops.
Requirements gathering for assistive technology that includes low vision and sighted users BIBAFull-Text 25-31
  Stephanie Ludi; Alex Canter; Lindsey Ellis; Abhishek Shrestha
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.
Interplay of usability and requirements engineering in facts analysis for patent disputes BIBAFull-Text 32-35
  Edna Rosen
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, structured method and software for analyzing and representing facts indicating the (non)obviousness of an invention. Different qualitative research methods are used to elicit and analyze usability issues. This paper describes first attempts on how acceptance of the FSTP method and software may be enhanced by a user-centered approach comprising: identifying learnability issues of the method, creating training accordingly, and uncovering usability issues of the existing prototype. The analysis of facts for a dispute is a creative and lengthy process that requires a lot of different skills (also with respect to regional specificities in patent law). The data collected represents a small sample of users with different background knowledge (i.e. (patent) lawyers) and cases of different patent law systems (i.e. USA and Europe).
Towards a usability requirements taxonomy for mobile AAC services BIBAFull-Text 36-39
  Hrvoje Belani
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 usability and accessibility requirements gathering for ICT services for aided augmentative and alternative communication (AAC), this paper presents directions towards building usability requirements taxonomy for mobile AAC services. Analysis of influential factors for building proper requirements specification for an AAC service is given. Outlines for new paradigm of so-called augmentative requirements engineering (ARE) are presented, demanding holistic view on service requirements concerning users abilities and needs, service domain and associated intermediary users.
