The following paper deals with quality properties that extend the traditional understanding of usability with its focus on the pragmatic aspects like efficiency and effectiveness on task performance in the context of business applications. The contribution of the approach is tow folded. First: We show how psychological theories about motivation and creativity can bridge the gap between business goals and users' goals and attitude with interaction design. We introduce an engineering approach that allows to deliberately design for fun/joy in a given business context. Second: We show how to reuse the experience from former or other projects by describing the interaction design as pattern candidates. This approach has been applied successfully many times and we elaborate it in a case study conducted for one of our clients, including an empirical evaluation that shows an improved working behavior and increased user acceptance of the software.

One of the challenges faced by developers of applications for smart environments is the diversity of contexts of use. Applications in smart environments must cope with continuously changing context of use, so the developers need to prepare them for a possibly broad range of situations. Since the developer has no access to all environments, in which her application will be executed, it must be possible to simulate different environments and evaluate the behavior of the application at design time. In our demonstration the designer has the possibility to simulate and modify a runtime context model and observe as her application adapts on the fly. In the underlying runtime architecture applications, defined as sets of models, are adapted automatically on the basis of the information held in the runtime context model. A visual tool enables the user interface developer to access and modify the models at any time and immediately observe the behavior of the application.
Information systems UI (User Interface) generation from declarative models has been the focus of numerous and various approaches in the human computer interaction community. Typically, the different approaches use the...

Documenting accidents and incidents in a clear, precise and unambiguous way is essential to ground studies of human error and to propose preventive measures. Research in this field has yielded many taxonomies and methods of categorizing error which are used by companies when analyzing and reporting accidents and incidents. There are difficulties, however, regarding the appropriateness of the terms applied to a company's specific context, since taxonomies tend to be specific. Moreover, the lack of a clear organization and the adoption of concepts which are not universally accepted among users with different backgrounds renders these taxonomies problematic. This paper proposes a taxonomy, and an associated supporting tool, for the description of accidents and incidents in the operation of electrical systems. The proposed taxonomy addresses the concepts and the terms related to the causes of error as well as concepts related to the user cognitive processes that led to the error.

The topics discussed include: bridging models andsystems at runtime to build adaptive user interfaces;software refactoring process for adaptive user-interface composition;how assessing plasticity design choices can improve UI quality: a case study;using ensembles of decision trees to automate repetitive tasks in web applications;user interface design by sketching: a complexity analysis of widget representations;an automated routine for menu structure optimization;sketched menu: a tabletop-menu technique for GUI object creation;COMM notation for specifying collaborative and multimodal interactivesystems;representations for an iterative resource-based design approach;user interface model discovery: towards a generic approach;taxonomy proposal for the description of accidents and incidents in the electrical systems operation;and an integrated environment supporting co-execution of tasks andsystems models.
To fulfil the requirements of emerging trends in mobile interaction, common patterns for system design need adaptations and extensions. The realization of explicit interaction in ambient or pervasive computing environ...

Language engineering underpins model-driven engineering and the application of domain-specific languages. In this talk, I will introduce language engineering and its principles and practices, using model-driven engineering as an exemplar. I will suggest how the engineering of interactivesystems offers opportunities, challenges and the potential for chaos for language engineering.

Accessibility is usually the last feature taken into account when designing interactivesystems (in case that it is considered at all) [4]. The most important barriers to accessibility are frequently embedded in the own structure of the system and cannot be removed without a painful reengineering process [1]. Too frequently designers decide to skip deep changes arguing that accessibility is expensive, time consuming, and only sporadically necessary [2]. If the objective is to produce accessible interactivesystems, using design methods that take into account the accessibility from the conceptualization of the system can save time and money [5]. In this talk I will present arguments to embrace accessibility as an important feature of the design [3], illustrated with examples of good and bad practices of the design for accessibility.
