    Design and Evaluation of a User Interface to Facilitate Cardiac Monitoring
    (Mensch und Computer 2017 - Tagungsband, 2017) Aures, Christina; Beuter, Christian; Kirsch, Alexandra
    Patient monitoring devices are complex and highly specialized systems. We present an enhanced display of the alarms that facilitates cardiac monitoring and supports the clinicians during the diagnosis process. Three different interactive user interface prototypes were developed using web technologies. To maximize acceptance among professionals, we extended the ECG parameter of an existing monitoring interface with visual cues directly at the wave, to show where exactly an alarm happened, an alarm timeline beneath the wave (showing the last events) and an animated detailed view of an event. The new user interface lowered the perceived cognitive load and accelerated the detection of abnormalities in the wave.

    Design and implement a mobile-based system to teach traffic signs to illiterate people
    (i-com: Vol. 21, No. 3, 2022) Alfayez, Zainab Hameed
    Nowadays, most information and communication technologies target literate users and neglect the 800 million illiterate individuals around the world. Although there have been several attempts to develop systems that help illiterate people and try to reduce the digital gap between them and those who are literate, it is still challenging to find accessible systems for illiterate people. This research aims to reduce the digital gap between illiterate and literate people in Iraq through developing a mobile application for learning traffic signs. Firstly, a requirement elicitation study was conducted to explore a set of design considerations and build an accessible interface for illiterate people. The study resulted in several design principles, such as using voice instructions, focusing on graphic content, and using the local language. Then, the mobile application was developed based on these design principles. Finally, an evaluation study was conducted to measure the usability of the developed application. The results revealed that the built application is efficient and effective, and the users were extremely satisfied in several aspects, such as easy usage and learnability, and declared that they would use it in the future and recommend it to others.

    Exploration of a Mobile Design for a Privacy Assistant to Help Users in Sharing Content in Online Social Networks
    (Mensch und Computer 2022 - Workshopband, 2022) Kqiku, Lindrit; Dieterle, Jakob; Reinhardt, Delphine
    Currently available Online Social Network (OSN) solutions with which users can select the audience with whom they want to share online content have been shown to be inefficient in protecting their privacy. As a result, users may either censure themselves or post information about themselves that they may later regret. To address the shortcomings of existing solutions, we propose to rely on a privacy assistant that will help the users in their audience selection. Among the necessary steps for its design, we focus in this paper on the visible tip of the iceberg, i.e., the interface that will present the suggestion to the users. Our interface addresses our defined criteria and is dedicated to mobile devices. In this first design phase, we have implemented and evaluated our proposed solution with ten participants using System Usability Scale (SUS). We have reached a SUS score of 70.75 and found out that our proposed interface is usable and easy to understand.We finally discuss possible improvements and challenges for designing and evaluating such interfaces.

    Generating User Interface Documentation Based on Imported Service Models
    (Softwaretechnik-Trends Band 39, Heft 2, 2019) Bünder, Hendrik
    Modernization of software systems often starts with replacing the graphical user interface (GUI), while the existing services are reused. Besides specifying the new user interface, supporting material such as system and user documentation have to be created. The paper introduces a model-driven approach to create new user interfaces based on existing service definitions. Additionally, it will be shown how the user interface model can be utilized to automatically generate system and user documentation based on the input and output parameters of the existing services and their documentation.

    Interfaceeffekte zwischen Metapher, Sound und Environmentalitäten: Zur Aneignung digital-haptischer Musik-Devices in professionellen musikalischen Kontexten
    (Mensch und Computer 2022 - Workshopband, 2022) Wernicke, Carsten; Ahlers, Michael
    Die immer stärker digitalisierten Berufspraktiken, auch in kreativer Hinsicht, stellen für professionelle Musiker*innen und Instrumentalpädagog* innen weiterhin große Herausforderungen dar. Insbesondere neue MusikmachDinge nehmen bestehende musikalische Praktiken und Techniken auf und entwickeln sie spezifisch weiter. Dieser Prozess ist nicht störungsfrei und kann in der musikalischen Praxis zu Irritationen führen. Der Artikel fasst einige wichtige Konsequenzen zusammen, die die Autoren auf den Ebenen von Gendereffekten, Instrumentalmetaphern, Demokratisierungsversprechen und Problemlösestrategien bei Aneignungsprozessen identifiziert haben. Davon ausgehend plädieren sie für eine stärkere Berücksichtigung intersektionaler Aspekte bereits beim Herstellungsprozess von MusikmachDingen.

    Privacy Needs Reflection: Conceptional Design Rationales for Privacy-Preserving Explanation User Interfaces
    (Mensch und Computer 2021 - Workshopband, 2021) Sörries, Peter; Müller-Birn, Claudia; Glinka, Katrin; Boenisch, Franziska; Margraf, Marian; Sayegh-Jodehl, Sabine; Rose, Matthias
    The application of machine learning (ML) in the medical domain has recently received a lot of attention. However, the constantly growing need for data in such ML-based approaches raises many privacy concerns, particularly when data originate from vulnerable groups, for example, people with a rare disease. In this context, a challenging but promising approach is the design of privacy-preserving computation technologies (e.g. differential privacy). However, design guidance on how to implement such approaches in practice has been lacking. In our research, we explore these challenges in the design process by involving stakeholders from medicine, security, ML, and human-computer interaction, as well as patients themselves. We emphasize the suitability of reflective design in this context by considering the concept of privacy by design. Based on a real-world use case situated in the healthcare domain, we explore the existing privacy needs of our main stakeholders, i.e. medical researchers or physicians and patients. Stakeholder needs are illustrated within two scenarios that help us to reflect on contradictory privacy needs. This reflection process informs conceptional design rationales and our proposal for privacy-preserving explanation user interfaces. We propose that the latter support both patients’ privacy preferences for a meaningful data donation and experts’ understanding of the privacy-preserving computation technology employed.

    The BMW i3 HMI - Holistic user interface engineering for e-mobility
    (UP14 - Vorträge, 2014) Knoll, Christian; Vilimek, Roman; Schulze, Inken
    BMW i, as a sub-brand of the BMW Group, targets on delivering sustainable solutions for individual mobility. One of the most important steps on this path was the introduction of the all-electric BMW i3 in 2013. In order to design not only the vehicle in itself, but also especially the newly developed electric vehicle related functions for optimal customer experience, the HMI design process substantially relied on repeated usability testing and large international field trials. With more than 34 million test kilometers absolved during the MINI E and the BMW ActiveE field trials an extraordinary knowledge base about customer needs related to e-mobility contributed valuable input to the development of the user interface of the BMW i3 and HMI challenges beyond the vehicle like charging wallbox, smartphone app and web portal related to driving electric. The presentation reports on the unique process of defining the user interface of the BMW Group’s first purpose-designed electric vehicle including the non-vehicle-based e-mobility infrastructure components. Based on selected use cases, the interplay between evolutionary steps in the HMI and continued usability testing shows how user-centered design is applied for a completely new kind of vehicle, thus providing insights on the necessities of iterative testing for disruptive innovations.

    Understanding and designing for control in camera operation
    (2019) Hösl, Axel
    Cinematographers often use supportive tools to craft desired camera moves. Recent technological advances added new tools to the palette such as gimbals, drones or robots. The combination of motor-driven actuation, computer vision and machine learning in such systems also rendered new interaction techniques possible. In particular, a content-based interaction style was introduced in addition to the established axis-based style. On the one hand, content-based cocreation between humans and automated systems made it easier to reach high level goals. On the other hand however, the increased use of automation also introduced negative side effects. Creatives usually want to feel in control during executing the camera motion and in the end as the authors of the recorded shots. While automation can assist experts or enable novices, it unfortunately also takes away desired control from operators. Thus, if we want to support cinematographers with new tools and interaction techniques the following question arises: How should we design interfaces for camera motion control that, despite being increasingly automated, provide cinematographers with an experience of control? Camera control has been studied for decades, especially in virtual environments. Applying content-based interaction to physical environments opens up new design opportunities but also faces, less researched, domain-specific challenges. To suit the needs of cinematographers, designs need to be crafted with care. In particular, they must adapt to constraints of recordings on location. This makes an interplay with established practices essential. Previous work has mainly focused on a technology-centered understanding of camera travel which consequently influenced the design of camera control systems. In contrast, this thesis, contributes to the understanding of the motives of cinematographers, how they operate on set and provides a user-centered foundation informing cinematography specific research and design. The contribution of this thesis is threefold: First, we present ethnographic studies on expert users and their shooting practices on location. These studies highlight the challenges of introducing automation to a creative task (assistance vs feeling in control). Second, we report on a domain specific prototyping toolkit for in-situ deployment. The toolkit provides open source software for low cost replication enabling the exploration of design alternatives. To better inform design decisions, we further introduce an evaluation framework for estimating the resulting quality and sense of control. By extending established methodologies with a recent neuroscientific technique, it provides data on explicit as well as implicit levels and is designed to be applicable to other domains of HCI. Third, we present evaluations of designs based on our toolkit and framework. We explored a dynamic interplay of manual control with various degrees of automation. Further, we examined different content-based interaction styles. Here, occlusion due to graphical elements was found and addressed by exploring visual reduction strategies and mid-air gestures. Our studies demonstrate that high degrees of quality and sense of control are achievable with our tools that also support creativity and established practices.

    Use Cases and Concepts for 3D Visualisation in Manufacturing
    (Informatik 2007 – Informatik trifft Logistik – Band 2, 2007) Wolf, Bernhard; Mofor, Gerald; Rode, Jochen
    We propose and analyse six use cases for 3D visualisation in manufacturing attempting to identify business scenarios for which 3D visualisation can add value in supporting manufacturing operations. This early qualitative work is based on a theoretical analysis of potential use cases. In addition to the analysis, we discuss the required data and data sources, and finally propose a number of basic concepts for visualising different kinds of manufacturing data.
