- ZeitschriftenartikelDie Gesetze der Einfachheit. Eine Buchbesprechung von John Maedas Laws of Simplicity(MMI Interaktiv - User Experience: Vol. 1, No. 13, 2007) Winkler, ThomasZunehmend werden wir mit Technologie konfrontiert, deren Handhabung viel zu kompliziert ist. Die Vielzahl von Funktionalitäten wird immer unüberschaubarer. Da wünschen wir uns Einfachheit und Überschaubarkeit in der Handhabung. Gleichzeitig möchten wir aber auch komplexe Prozesse steuern können und uns außerdem mit den Geräten, die wir besitzen, identifizieren. Gut gestaltete technische Geräte sollten komplexe Prozesse einfach steuerbar machen. Gleichzeitig sollten sie dem Ausdruck von individueller Persönlichkeit dienen und deshalb nicht zu gleichförmig sein.

- ZeitschriftenartikelMensch-Technik-Interaktion: intuitiv, erwartungskonform oder vertraut?(MMI Interaktiv - User Experience: Vol. 1, No. 13, 2007) Mohs, Carsten; Naumann, Anja; Kindsmüller, Martin ChristofDie Forderung nach intuitiver Benutzbarkeit technischer Systeme wird in der heutigen Zeit immer nachdrücklicher geäußert. Die Frage ist allerdings, wie sich intuitive Benutzbarkeit von anderen Konzepten und bestehenden Normen, wie z.B. Erwartungskonformität, zu der häufig eine große Ähnlichkeit angenommen wird, abhebt. In der vorliegenden Arbeit werden daher zunächst die Begriffe bzw. Konzepte Vertrautheit, Erwartung und Intuition analysiert und verglichen. In einem zweiten Schritt wird die Bedeutung dieser unterschiedlichen Konzepte für die Usability und die Systemgestaltung aufgezeigt. Hierbei werden zunächst Erwartungen der Nutzer an technische Systeme dargestellt. Im Anschluss werden spezifische Vorschläge sowohl für eine Gestaltung erwartungskonformer als auch intuitiv bedienbarer Systeme abgeleitet, wobei die Zielgruppenspezifität als zentrales Unterscheidungsmerkmal herausgearbeitet wird.
- ZeitschriftenartikelEmpirical investigations into intuitive interaction: a summary(MMI Interaktiv - User Experience: Vol. 1, No. 13, 2007) Blackler, Alethea; Popovic, Vesna; Mahar, Douglas PatrickIntuition is a type of cognitive processing that is often non-conscious and utilises stored experiential knowledge. Intuitive interaction involves the use of knowledge gained from other products and/or experiences. We have developed novel approaches and techniques for studying intuitive use of interfaces, and shown that intuitive interaction is based on past experience with similar things (Blackler, Popovic, and Mahar, 2003a, b, 2004a, b, 2005). Two initial experimental studies revealed that prior exposure to products employing similar features helped participants to complete set tasks more quickly and intuitively, and that familiar features were intuitively used more often than unfamiliar ones. A third experiment revealed that appearance of features seems to be the variable that most affects time spent on a task and intuitive uses. Based on our empirical work, we have developed principles and tools for designers to assist them in making interfaces more intuitive.
- ZeitschriftenartikelTowards a unified view of intuitive interaction: definitions, models and tools across the world(MMI Interaktiv - User Experience: Vol. 1, No. 13, 2007) Blackler, Alethea; Hurtienne, JörnTwo previously independent approaches to investigating intuitive interaction in Australia and Germany are described and compared. Both definitions are based on the literature and so agree very closely, involving the non-conscious use of prior knowl-edge for intuitive interaction. Models have been devised by both groups: a continuum of intuitive interaction and a continuum of prior knowledge. Although there are points of difference in the models it is found that these are minimal and that the models are complementary. Tools like design methodologies, design principles, questionnaires, and an online database have been devised by the two groups that can contribute to helping designers in making user interfaces more intuitive to use.
- ZeitschriftenartikelThe Diversity of Non-instrumental Qualities in Human-Technology Interaction(MMI Interaktiv - User Experience: Vol. 1, No. 13, 2007) Mahlke, Sascha; Lemke, Iris; Thüring, ManfredQuality aspects that go beyond the instrumental value of an interactive system are one area of research in the field of user experience. In this paper, we describe an approach to the measurement of non-instrumental qualities that defines aesthetic and symbolic aspects as main sub-categories and discuss further relevant sub-dimensions. An exemplary study on three mobile phones is presented that used the discussed assumptions as theoretical basis and applied various questionnaire dimensions from the literature. The results demonstrate the usefulness of the approach and show that a consideration of diverse aspects of non-instrumental qualities makes is possible to better explain usersâ overall judgments. Implications for the evaluation and design of interactive systems and future work are discussed.
- ZeitschriftenartikelSymbolic Aspects of University Homepage Design: What Appeals to Different Cultures?(MMI Interaktiv - User Experience: Vol. 1, No. 13, 2007) Sen, Devjani; Lindgaard, Gitte; Patrick, AndrewUniversity homepages often provide the first introduction to a university for many students in an increasingly global world. As a result, a university s ability to attract new students may rest in large part on the ability of a website to attract and hold the attention of its intended audience. The purpose of this exploratory study was to examine potential cross-cultural differences in 'persuasive appeals' which may influence how much people from varying cultural backgrounds may trust university homepages. More specifically, this paper attempts to identify cultural differences in the symbolic aspects of these persuasive appeals in university homepages through the identification of cultural markers in message content guided by Hofstede's (1980). As the ultimate aim of this study is to design guidelines for developers of university websites that will cater to a global audience, the goals for this preliminary work are to (1) identify cultural differences in symbolic appeals in university homepages and (2) provide design guidelines for university homepages that are pertinent to, and will hold, persuasive appeal for the end user's cultural mind set. Two initial models, derived from the findings of this study are offered on how cultural differences may influence the impact of persuasive appeals in university homepages. The central findings are discussed in terms of some preliminary implications for future web design.
- ZeitschriftenartikelUntersuchung von Designpräferenzen mit Hilfe von Skalierungsmethoden(MMI Interaktiv - User Experience: Vol. 1, No. 13, 2007) Schrepp, Martin; Held, Theo; Fischer, PatrickWir untersuchen die Anwendbarkeit zweier klassischer Skalierungsverfahren (BTL-Skalierung und Conjoint-Analyse) auf die Untersuchung ästhetisch motivierter Präferenzen zwischen Benutzungsoberflächen. Die Anwendung beider Verfahren wird jeweils an einer Studie zum Design von Eingabeformularen illustriert. Die Ergebnisse dieser beiden Studien zeigen, dass beide Skalierungsmethoden als effektive Unterstützung zur Lösung von Entscheidungsproblemen im Bereich des Oberflächendesigns dienen können.
- ZeitschriftenartikelAnimation and Continuity: Prerequisites for Intuitive Interaction(MMI Interaktiv - User Experience: Vol. 1, No. 13, 2007) Ginnow-Merkert, HartmutA user's ability to approach a complex technical system intuitively depends on the proper design of the software (and hardware) structures representing its functional repertoire. If we learn to design and present the functionality of a technical product – or system – analog to some of the qualities of the “Real World”, we enable users to rely on their genetically predetermined or acquired behavioral inventory. Thus interfaces need not to be learned, they appear natural at the first glance. Essential design parameters are the principles of continuity and animation. This paper represents and illustrates the author's argument indicated in the title.
