    Affinity for technology interaction and fields of study: implications for human-centered design of applications for public administration
    (Mensch und Computer 2020 - Tagungsband, 2020) Wessel, Daniel; Heine, Moreen; Attig, Christiane; Franke, Thomas
    Affinity for Technology Interaction (ATI) describes whether a person approaches or avoids interaction with technology [1], making it an important variable in human-centered design. To determine whether ATI will likely remain an important variable in the future, we compared the ATI scores of those who will develop applications (students of media and computer science) with those who will use them in a specific context (students of public administration). We also looked for possible selection biases when conducting online samples regarding technology, by comparing a self-selected online sample of public administration employees with a sample of students of public administration conducted in a classroom, in which no selection biases should have had occurred. To locate the samples in the general population we also compared them with a quota sample of the German population. Results indicate markedly different approaches to technology interaction between the student samples and the online sample being more similar to the media and computer science students. We discuss consequences for the human-centered design process, especially for understanding the users.

    Communicating Robotic Help Requests: Effects of Eye-Expressions, LED-Lights and Polite Language
    (i-com: Vol. 19, No. 2, 2020) Westhoven, Martin; Grinten, Tim van der
    In this paper we report results from a web- and video-based study on the perception of a request for help from a robot head. Colored lights, eye-expressions and politeness of the used language were varied. We measured effects on expression identification, hedonic user experience, perceived politeness, and help intention. Additionally, sociodemographic data, a ‘face blindness’ questionnaire, and negative attitudes towards robots were collected to control for possible influences on the dependent variables. A total of n = 139 participants were included in the analysis. In this paper, the focus is placed on interaction effects and on the influence of covariates. Significant effects were found for the interaction of LED lighting and eye-expressions and for language and eye-expressions on help intention. The expression identification is significantly influenced by the interaction of LED lighting and eye-expressions. Several significant effects of the covariates were found, both direct and from interaction with independent variables. Especially the negative attitudes towards robots significantly influence help intention and perceived politeness. The results provide information on the effect of different design choices for help requesting robots.

    Constant Companion. How Frequent Phone Use and Interpersonal Communication Are Related to Users’ Emotional Appraisal
    (Mensch und Computer 2021 - Tagungsband, 2021) Arlinghaus, Clarissa Sabrina; Ollermann, Frank
    Emotional appraisal is a core aspect of user experience. This study examines whether frequency of mobile phone use can have an impact on emotional aspects of mobile phone user experience. It also comments on the role of interpersonal communication for emotional evaluation. The results of an online survey in Germany (N = 836) reveal that frequencies are related to positive and negative emotions differently. Frequent phone users experience more positive emotions than others, but the frequent use of a mobile phone does not seem to reduce negative emotions. Surprisingly, this effect does not depend on the extent of interpersonal communication. Positive emotions seem to be stronger connected to a positive user experience, whereas negative emotions probably occur due to a bad usability. This can be interpreted as an evidence for Herzberg’s two-factor theory applied to user experience.

    Construction of UEQ+ scales for voice quality: measuring user experience quality of voice interaction
    (Mensch und Computer 2020 - Tagungsband, 2020) Klein, Andreas M.; Hinderks, Andreas; Schrepp, Martin; Thomaschewski, Jörg
    The UEQ+ is a modular framework for the construction of UX questionnaires. The researcher can pick those scales that fit his or her research question from a list of 16 available UX scales. Currently, no UEQ+ scales are available to allow measuring the quality of voice interactions. Given that this type of interaction is increasingly essential for the usage of digital products, this is a severe limitation of the possible products and usage scenarios that can be evaluated using the UEQ+. We describe in this paper the construction of three specific scales to measure the UX of voice interactions. Besides, we discuss how these new scales can be combined with existing UEQ+ scales in evaluation projects.

    Design and Virtual Studio Presentation of a Traditional Archery Simulator
    (Mensch & Computer 2010 Entertainment Interfaces Track, 2010) Geiger, Christian; Herder, Jens; Göbel, Sebastian; Heinze, Christin; Marinos, Dionysios
    In this paper we describe the design of a virtual reality simulator for traditional intuitive archery. Traditional archers aim without a target figure. Good shooting results require an excellent body-eye coordination that allows the user to perform identical movements when drawing the bow. Our simulator provides a virtual archery experience and supports the user to learn and practice the motion sequence of traditional archery in a virtual environment. We use an infrared tracking system to capture the user’s movements in order to correct his movement. To provide a realistic haptic feedback a real bow is used as interaction device. Our system provides a believable user experience and supports the user to learn how to shoot in the traditional way. Following a user-centered iterative design approach we developed a number of prototypes and evaluated them for refinement in sequent iteration cycles. For illustration purposes we created a short video clip in our virtual studio about this project that presents the main ideas in an informative yet entertaining way.

    Engineering Mobile User Experience: Think. Design. Fail. Iterate. Publish.
    (Mensch & Computer 2011: überMEDIEN|ÜBERmorgen, 2011) Heckner, Markus; Schneidermeier, Tim; Bazo, Alexander; Wagner, Thomas; Wilhelm, Thomas; Wolff, Christian
    Der Vertrieb von Smartphone-Applikationen über zentralisierte Marktplätze, wie Android Market, Apple iTunes oder Nokia Ovi Store ist heute fest etabliert. Dieser Vertriebsweg bietet Chancen, aber auch Risiken für die Entwickler: Die Nutzer erhalten einen direkten Feedbackkanal, auf dem sie Applikationen für alle anderen Nutzer sichtbar bewerten und kommentieren können. User Experience ist hier ein Schlüssel zum Erfolg einer App. Gleichzeitig erfordert die starke Konkurrenz durch die hohe Anzahl von Entwicklern ständig innovative neue Produkte, um sich von bestehenden Angeboten zu differenzieren. In diesem Praxisbericht wird ein Vorgehensmodell vorgeschlagen, das den Nutzer ins Zentrum jeder mobilen Anwendungsentwicklung stellt, mit dem Ziel, effizient Software zu entwickeln, die tatsächliche Probleme der Nutzer löst und sich durch positive User Experience auszeichnet. Anhand eines konkreten Projekts wird der erfolgreiche Einsatz des Modells dokumentiert und abschließend diskutiert.

    Exploring Dynamic Vibrotactile Feedback for Layer-based Interaction on Elastic Displays
    (Mensch und Computer 2023 - Tagungsband, 2023) Müller, Mathias; Ramian, Alexander; Wittchen, Dennis; Freitag, Georg; Kammer, Dietrich
    Elastic Displays are shape-changing interfaces, typically made from elastic fabric. Surface deformation creates an additional dimension of interaction and enhances the haptic experience for the user compared to rigid touch interfaces. Other forms of shape-changing interfaces such as actuated displays introduce significant mechanical complexity with the benefit of providing active haptic feedback and self-deformation. We investigate ways to make Elastic Displays more ‘active’ while maintaining their simple setup. Our approach adds vibrotactile feedback to the elastic surface, which add explicit haptic feedback when pushing and pulling the surface. In this contribution, we describe the technical setup and introduce concepts for exploring this active haptic feedback. We realized a case study, in which a layered information space is explored. Finally, we report lessons learned from user feedback, showing that solely vibrotactile feedback may have distracting effects on the user, but in combination with visual feedback can improve the user experience.

    Growth Marketing Considered Harmful
    (i-com: Vol. 20, No. 1, 2021) Speicher, Maximilian
    In today’s e-commerce industry, conversion rate optimization is often considered essentially the same as user experience optimization. In addition, there is a strong focus on quantitative experimentation, which some deem a jack-of-all-trades solution, often at the expense of qualitative user experience research. Both are worrying developments. This essay elaborates on why it is harmful to consider conversion rate optimization and user experience optimization to be the same thing in the context of growth marketing, and how the three concepts are interrelated.

    The Impact of Explanation Detail in Advanced Driver Assistance Systems: User Experience, Acceptance, and Age-related Effects
    (Mensch und Computer 2023 - Tagungsband, 2023) Hermann, Julia; Nierobisch, Niels; Arndt, Robin; Kubullek, Ann-Kathrin; van Ledden, Sebastian; Dogangün, Aysegül
    User understanding and confidence are critical in the context of advanced intelligent driver assistance systems (ADAS) to ensure the desired response and prevent manual countersteering during automated maneuvers. However, the interventions of advanced ADAS can sometimes be unexpected and disruptive to drivers, especially when the reasons are unclear. In our study, we investigated the effects of differently presented explanations provided by a driver assistance system. We presented participants with three scenarios from the driver’s perspective and created two videos for each scenario with explanations of varying detail. Participants were asked to answer two questionnaires following each video. The results show that more detailed explanations generally lead to a better user experience and higher confidence in the system’s performance. We also discuss the possible influence of age and technology acceptance in our article.
