- ZeitschriftenartikelAnalysing Interactivity in Information Visualisation(KI - Künstliche Intelligenz: Vol. 26, No. 2, 2012) Pohl, Margit; Wiltner, Sylvia; Miksch, Silvia; Aigner, Wolfgang; Rind, AlexanderModern information visualisation systems do not only support interactivity but also increasingly complex problem solving. In this study we compare two interactive information visualisation systems: VisuExplore and Gravi++. By analysing logfiles we were able to identify sets of activities and interaction patterns users followed while working with these systems. These patterns are an indication of strategies users adopt to find solutions. Identifying such patterns may help in improving the design of future information visualisation systems.
- ZeitschriftenartikelCollaborative Multimodality(KI - Künstliche Intelligenz: Vol. 26, No. 2, 2012) Sonntag, DanielThis essay is a personal reflection from an Artificial Intelligence (AI) perspective on the term HCI. Especially for the transfer of AI-based HCI into industrial environments, we survey existing approaches and examine how AI helps to solve fundamental problems of HCI technology. The user and the system must have a collaborative goal. The concept of collaborative multimodality could serve as the missing link between traditional HCI and intuitive human-centred designs in the form of, e.g., natural language interfaces or intelligent environments. Examples are provided in the medical imaging domain.
- ZeitschriftenartikelDesigning for a Moving Target(KI - Künstliche Intelligenz: Vol. 26, No. 2, 2012) Veer, Gerrit C.User centered design is a relatively young design approach. Over the years, user centered design changed its scope. However, the concept of usability does not just expand by broadening the view on ease of use and learning. Experience is added in the nineties and in 2006 we find Apple suggest its iPod users to “Enjoy Uncertainty.” The history of user centered design (or human-computer interaction, or cognitive ergonomics) shows the development of the design approach as a movement in different dimensions: from the reign of functionality to attention to individual users in context;from user control to experience and entertainment; andfrom a culturally defined cost-benefit goal to perspective on a multitude of design cultures and cultures of use.
- ZeitschriftenartikelHuman-Computer Interaction(KI - Künstliche Intelligenz: Vol. 26, No. 2, 2012) Ebert, Achim; Gershon, Nahum D.; Veer, Gerrit C.Human-Computer Interaction (HCI) is a term known since the early 1980s. In HCI, the user plays the central role, much more than the computer hardware or software by itself. It is a multi-disciplinary research field, populated by researchers and practitioners from areas like psychology and cognitive sciences, ergonomics, sociology, computer science, graphic design, business, and more. In order to build really usable interfaces, the knowledge and engagement of every single related field are basic prerequisites. We are taking a look on how selected areas have contributed to HCI in recent years.
- ZeitschriftenartikelIncorporating Usability Evaluation in Software Development Environments(KI - Künstliche Intelligenz: Vol. 26, No. 2, 2012) Humayoun, Shah RukhWe propose a way to define and automate user and usability evaluation from within the integrated development environment (IDE). Specifically, for the automatic analysis of usability issues and functionality problems, we provide a framework for conducting evaluation experiments using TaMoGolog-based formal task models. This approach enables the software development team to automatically collect and analyze users and system activities and behavior for recognizing usability issues and functionality problems in an efficient and effective way. The developed tools, UEMan and TaMUlator, provide the realization of the proposed approach and framework at the IDE level.

- ZeitschriftenartikelJubiläums-Fragen – Zum 25. Jahrgang von KI(KI - Künstliche Intelligenz: Vol. 26, No. 2, 2012) Nagel, Hans-HellmutDie Auseinandersetzung mit der Vergangenheit hilft, die Zukunft zu gestalten. Die Existenz des Periodicums KI für nunmehr ein Vierteljahrhundert bietet Anlass, Fokus und Fundus für eine solche Auseinandersetzung. Die nachfolgenden Fragen laden die derzeit aktive Generation ein darüber nachzudenken, wie das Arbeitsgebiet Künstliche Intelligenz im vergangenen Vierteljahrhundert in Deutschland umrissen und behandelt worden ist. Ergänzend wird im dritten Abschnitt kurz auf drei zusätzliche Denkanstöße für Rückblick und Ausblick eingegangen.

- ZeitschriftenartikelMeasuring Subjectivity(KI - Künstliche Intelligenz: Vol. 26, No. 2, 2012) Cernea, Daniel; Olech, Peter-Scott; Ebert, Achim; Kerren, AndreasSince the dawn of the industrial era, modern devices and interaction methods have undergone rigorous evaluations in order to ensure their functionality and quality, as well as usability. While there are many methods for measuring objective data, capturing and interpreting subjective factors—like the feelings or states of mind of the users—is still an imprecise and usually post-event process. In this paper we propose the utilization of the Emotiv EPOC commercial electroencephalographic (EEG) neuroheadset for real-time support during evaluations and user studies. We show in two evaluation scenarios that the wireless EPOC headsets can be used efficiently for supporting subjectivity measurement. Additionally, we highlight situations that may result in a lower accuracy, as well as explore possible reasons and propose solutions for improving the error rates of the device.
