    An Intuitive Textile Input Controller
    (Mensch und Computer 2015 – Proceedings, 2015) Heller, Florian; Lee, Hyun-Young {Kriz}; Brauner, Philipp; Gries, Thomas; Ziefle, Martina; Borchers, Jan
    When thinking of textile interfaces, these are often imagined as being integrated into clothing. While this is the most prominent use of fabric, we present a standalone interface that builds on the natural set of interactions a piece of fabric affords, and that is feasible for industrial production. By integrating stitched patterns made of conductive thread into a square piece of fabric, we are able to sense established connections within this pattern and map these to a model how the cloth is folded. An integrated microcontroller tracks these connections and communicates them as two-dimensional continuous value changes to a host application. We present the technical construction of our prototype, a particular clip-on technique to establish the connection between fabric and electronics, and first insights into recognizing different grip gestures.

    Gardeene! Textile Controls for the Home Environment
    (Mensch und Computer 2016 - Tagungsband, 2016) Heller, Florian; Oßmann, Lukas; Hamdan, Nur; Brauner, Philipp; Van Heek, Julia; Scheulen, Klaus; Möllering, Christian; Goßen, Laura; Witsch, Rouven; Ziefle, Martina; Gries, Thomas; Borchers, Jan
    Textile controls so far, have mostly been envisioned to be integrated to clothing. In our environment, however, much more textile interaction surfaces are available. In this paper, we present a capacitive textile sensor, seamlessly integrated into a motorized curtain. While the basic functionality is simply to open and close the curtain, its design allows a much richer gestural interaction.

    Human Factors in Information Visualization and Decision Support Systems
    (Mensch und Computer 2016 – Workshopband, 2016) Valdez, André Calero; Brauner, Philipp; Ziefle, Martina; Kuhlen, Torsten Wolfgang; Sedlmair, Michael
    With the increase in data availability and data volume it becomes increasingly important to extract information and actionable knowledge from data. Information Visualization helps the user to understand data by utilizing vision as a relatively parallel input channel to the user’s mind. Decision Support systems on the other hand help users in making information actionable, by suggesting beneficial decisions and presenting them in context. Both fields share a common need for understanding the interface between the computer and the human. This makes human factors research critical for both fields. Understanding limitations of human perception, cognition and action, as well as their variance must be understood to fully leverage information visualization and decision support. This article reflects on research agendas for investigating human factors in the aforementioned fields.

    Modelling Human Factors in Cyber Physical Production Systems by the Integration of Human Digital Shadows
    (Modellierung 2022 Satellite Events, 2022) Mertens, Alexander; Brauner, Philipp; Baier, Ralph; Brillowski, Florian; Dammers, Hannah; Van Dyck, Marc; Kong, Iris; Königs, Peter; Kordtomeikel, Frauke; Liehner, Gian Luca; Pütz, Sebastian; Rodemann, Niklas; Schaar, Anne Kathrin; Steuer-Dankert, Linda; Vervier, Luisa; Wlecke, Shari; Gries, Thomas; Leicht-Scholten, Carmen; Nagel, Saskia K.; Piller, Frank T.; Schuh, Günther; Ziefle, Martina; Nitsch, Verena
    The future of industrial manufacturing and production will increasingly manifest in the form of cyber-physical production systems. Here, Digital Shadows will act as mediators between the physical and digital world to model and operationalize the interactions and relationships between different entities in production systems. Until now, the associated concepts have been primarily pursued and implemented from a technocentric perspective, in which human actors play a subordinate role, if they are considered at all. This paper outlines an anthropocentric approach that explicitly considers the characteristics, behavior, and traits and states of human actors in socio-technical production systems. For this purpose, we discuss the potentials and the expected challenges and threats of creating and using Human Digital Shadows in production.

    On Studying Human Factors in Complex Cyber-Physical Systems
    (Mensch und Computer 2016 – Workshopband, 2016) Brauner, Philipp; Valdez, André Calero; Philipsen, Ralf; Ziefle, Martina
    Deep penetration of modern information and communication technology in manufacturing companies (vertical integration) and across supply chains (horizontal integration) leads to an increasing amount and complexity of information that needs to be perceived, filtered, processed, and reacted to. Yet, the human factors that influence performance are insufficiently understood. This article outlines that individual factors, interface factors, and system factors affect overall performance and it presents two complementary research methodologies for identifying and quantifying these factors. On one side, we show that controlled laboratory experiments with singular decision tasks can precisely identify and quantify factors contributing to performance. On the other side, we use business simulation games with realistic decision tasks that can quantify the complexity of the underlying system. Our studies show that information amount, complexity, and presentation affect performance and that Decision Support Systems can increase performance and decrease error rates if and only if they are designed correctly. The article concludes with a research agenda to specifically understand which factors influence performance and how humans in the loop can be supported.

    Podcastproduktion als kollaborativer Zugang zur theoretischen Informatik
    (DeLFI 2010 - 8. Tagung der Fachgruppe E-Learning der Gesellschaft für Informatik e.V., 2010) Ábrahám, Erika; Brauner, Philipp; Jansen, Nils; Leonhardt, Thiemo; Loup, Ulrich; Schroeder, Ulrik
    Video-Podcasts und im speziellen Wissenschaftsfilme als Lehrund Lerngegenstand bieten vielseitige Möglichkeiten zur vereinfachten und verständlichen Darstellung von wissenschaftlichen Inhalten. Videos im Allgemeinen erfreuen sich großer Popularität unter Jugendlichen. Der Erfolg solcher Medien mit wissenschaftlichen Inhalten hängt stark davon ab, ob die Jugendlichen die Darstellung altersgerecht und ansprechend finden. Wir möchten dies erreichen, indem wir Jugendliche in die Erstellung solcher Filme einbeziehen. In einer fünftägigen universitären Veranstaltung zur Information von Schülerinnen und Schülern ab der 10. Jahrgangsstufe über das Studium der Informatik wurden in mehreren Kleingruppen verschiedene modulare Themen aus dem theoretischen Bereich der Verifikation erarbeitet. Mit der so erlangten Expertise erstellten die Teilnehmenden ein Video-Podcast um ein realitätsnahes Bild des Informatikstudiums zu vermitteln. Die Evaluierung der Veranstaltung zeigt den Erfolg und die Einsetzbarkeit dieses Ansatzes zur Wissensvermittlung.

    Preliminary findings of a gender and diversity screening at a technical university: impressions of the project “IGaDtools4MINT”
    (INFORMATIK 2011 – Informatik schafft Communities, 2011) Apel, Rebecca; Berg, Tobias; Holz, Jan; Brauner, Philipp; Schroeder, Ulrik; Wolffram, Andrea; Leicht-Scholten, Carmen
    In the paper at hand the project design of “IGaDtools4MINT”, a research project aiming to promote gender and diversity aspects as well as an opening of the faculty culture of computer science, is introduced. A first approximation on the reasons why women tend to study computer science and other MINT/STEM-subjects far less often than men will be given. Moreover, results of an initial survey of first semester students of computer science and impressions of a qualitative participant observation of different introductory courses of computer science at RWTH Aachen University are interpreted and discussed. The results of the evaluation allow for the assumption that efforts for the creation of a gender and diversity friendly environment which is a basic factor for the attraction of non-traditional, diverse students are visible but that these efforts to a large extent lack a coherent strategy and gender and diversity sensitivity to contribute to a sustainable structural and cultural change process within the department of computer science.

    Übertragbarkeit singulärer MINT-Interesse-initiierender außerschulischer Maßnahmen
    (Informatik in Bildung und Beruf – INFOS 2011 – 14. GI-Fachtagung Informatik und Schule, 2011) Leonhardt, Thiemo; Brauner, Philipp; Siebert, Jochen; Schroeder, Ulrik
    In diesem Artikel wird die Auswertung einer singulären Informatikund Technikinteresse-initiierenden Maßnahme geschildert. Dabei werden als maßgebliche Einflussfaktoren das Selbstkonzept, die Selbsteinschätzung, die Expertise im Umgang mit Technik und die Zukunftsperspektive im Informatik und naturwissenschaftlichen Bereich untersucht. Die Ergebnisse zeigen weder einen altersnoch einen geschlechtsspezifischen Effekt in der Wirkung des Kurses, jedoch erwartungsgemäß einen signifikanten Unterschied in der geschlechtsbedingten Prädisposition. Zur Untersuchung, ob erfolgreiche außerschulische monoedukative Maßnahmen auch in einem koedukativen Klassenverband gleiche Ergebnisse erzielen können, haben wir im zweiten Schritt eine kontrollierte Studie mit Schulklassen der Region Aachen durchgeführt. Durch diese Zufallsstichprobe können Alterseffekte oder ein Effekt durch die freiwillige Teilnahme am Kurs minimiert werden. Die Ergebnisse zeigen, dass erfolgreiche monoedukative Workshop-Konzepte auch in einem koedukativen Klassenverband vergleichbar wirken.

    Using Commercial Children's Smart Pens for Prototyping Interactive Science Communication Media in the Digital Transformation of Production
    (Mensch und Computer 2023 - Tagungsband, 2023) Brauner, Philipp; Schmeckel, Tim; Vervier, Luisa; Liehner, Gian Luca; Ziefle, Martina
    The Tiptoi smart pen has a huge fan following among children and their parents. Interacting with the pen makes it easy to see why: the pen has been designed to help children learn and explore complex information about a vast array of topics, from farms to learning about the human body. This work examined whether the Tiptoi pen could be similarly used to communicate science to the general public, taking a research project on the digital transformation of production as an example. Following an iterative design approach, we created an interactive book that allows self-directed engagement with the general research motivation, partners, and objectives of the project. Building on a SWOT analysis, we conducted qualitative semi-structured interviews with four subjects to evaluate the prototype. The evaluation was generally positive. Participants recognized the playful and appealing design, and the vivid and tangible knowledge transfer as strengths but were unhappy with the pen’s toy-like appearance. They also identified potential functions such as real factory sounds and narrative techniques to enhance storytelling as opportunities and mobile learning apps and virtual reality applications as threats. The article concludes with alternative use cases for smart pens and actionable implementation guidelines.
