Tools and techniques for requirements elicitation ure generally unsuitable for use with children and for innovative and futuristic developments. Using case studies, this paper explores practical methods to get requirements for future technologies from children. Techniques such as scenurio building, roleplaying and stog,boarding proved successflrl in involving children in the requirements process and stimulating innovation. The paper looks ut how these methods can be udopted to take u more jundumentul approach to requirements elicitation fijf;,r adults.These techniques help requirements engineers face the difJicult tusk of getting system requirements from users of whatever age, ability or background. They also enable requirements engineers to anticipate some of the future changes that might occur before or as a consequence of the installation of a new system. The lack of specialist notation was found to promote communication throughout the analysis and design process and gives the designers a context in which to design.
This article examines the impact of the Internet on the everyday lives of U.K. citizens through the integration of quantitative longitudinal time-use data and qualitative interviews. It shows that there is little significant change in people's time use that can be associated with their acquisition of an Internet connection and demonstrates the oversimplicity of the impact model for understanding the role of the Internet in everyday life. Instead, it suggests that life-style and/or lifestage transitions may trigger adoption of the Internet and, simultaneously, changes in domestic time use. It also demonstrates that Internet usage is too coarse a unit for sensible analysis. Rather, researchers need to consider the patterns of usage of the various applications or services that the Internet delivers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
