This paper presents the evaluation of usersХ experiences in three intelligent lighting pilots in Finland. Two of the case studies are related to the use of intelligent lighting in different kinds of traffic areas, having emphasis on aspects of visibility, traffic and movement safety, and sense of security. The last case study presents a more complex view to the experience of intelligent lighting in smart city contexts. The evaluation methods, tailored to each pilot context, include questionnaires, an urban dashboard, in-situ interviews and observations, evaluation probes, and system data analyses. The applicability of the selected and tested methods is discussed reflecting the process and achieved results.

The author conducted research to determine whether IT managers, IT auditors, users, management, etc. (all decision-makers) use a certain evaluation and selection process to acquire software to meet business objectives and the requirement of users. An argument was used that the more thorough the software evaluation and selection process, the more likely it would be that the organisation will chose software that meets these targets. The main objective of the research was therefore to determine whether Media24 uses evaluation methods and obtains the desired results. The results confirmed that Media24 uses suggested protocol as noted in the theory for software acquisition correctly during most stages.

User Centered

Usability and user experience are two important factors in the development of mass-customizable personalized products. A broad range of evaluation methods is available to improve products during an user-centered development process. This chapter gives an overview on these methods and how to apply them to achieve easy-to-use, efficient and effective personalized products that are additionally fun to use. A case study on the development of a new interaction technique for interactive TV helps to understand how to set up a mix of evaluation methods to cope with some of the limitations of current usability and user experience evaluation methods. The chapter concludes with some guidelines of how to change organizations to focus on usability and user experience.

The Impact

Abstract. Stochastic rainfall modelling is a commonly used technique for evaluating the impact of flooding, drought or climate change in a catchment. While considerable attention is given to the development of stochastic rainfall models, significantly less attention is given to performance evaluation methods. Typical evaluation methods employ a variety of rainfall statistics. However, they give limited understanding about which rainfall characteristics are most important for reliable streamflow prediction whenever the simulated rainfall are poor. To address this issue a new evaluation method for rainfall models is introduced, with three key features: (i) streamflow-based – to give a direct evaluation of modelled streamflow performance, (ii) virtual – to avoid the issue of confounding errors in hydrological models or data, and (iii) targeted – to isolate the source of errors according to specific sites and months. The virtual hydrologic evaluation framework is applied to a case study of 22 sites in South Australia. The framework demonstrated that apparently good modelled rainfall can produce poor streamflow predictions, whilst poor modelled rainfall may lead to good streamflow predictions, as catchment processes can dampen or amplify rainfall errors when converted to streamflow. The framework identified the importance of rainfall in the wetting-up months of the catchment cycle (May and June in this case study) for providing reliable predictions of streamflow over the entire year despite their low monthly flow volume. This insight would not have been found using existing methods and highlights the importance of the virtual hydrological evaluation framework for stochastic rainfall model evaluation.

Community Computing

End user development (EUD) tools in community computing are not well-developed and typically do not take into consideration the unique characteristics of community groups such as lack of human, financial, and technological resources. Using a case study, we explore EUD in the domain of community computing. Situated in community computing context, we identify design requirements of EUD tools, demonstrate the use of conceptual scaffolds to support EUD, and illustrate the need of new evaluation methods of EUD tools. We discuss the tension between pushing EUD tools to community computing for local autonomy on technology issues and the long time practice of seeking and relying on external technical expertise. We call for research studies that address the tension and explore ways of creating and stimulating “pull” force from the community groups.
