    A European Perspective on Crisis Informatics: Citizens’ and Authorities’ Attitudes Towards Social Media for Public Safety and Security
    (2022) Reuter, Christian
    Mobilising helpers in the event of a flood or letting friends know that you are okay in the event of a terrorist attack – more and more people are using social media in emergency, crisis or disaster situations. Storms, floods, attacks or pandemics (esp. COVID-19) show that citizens use social media to inform themselves or to coordinate. This book presents qualitative and quantitative studies on the attitudes of emergency services and citizens in Europe towards social media in emergencies. Across the individual sub-studies, almost 10,000 people are surveyed including representative studies in the Netherlands, Germany, the UK and Italy. The work empirically shows that social media is increasingly important for emergency services, both for prevention and during crises; that private use of social media is a driving force in shaping opinions for organisational use; and that citizens have high expectations towards authorities, especially monitoring social media is expected, and sometimes responses within one hour. Depending on the risk culture, the data show further differences, e.g. whether the state (Germany) or the individual (Netherlands) is seen as primarily responsible for coping with the situation.

    Designing communication technologies based on physiological sensing
    (2018) Hassib, Mariam
    The human body, that marvelous chamber of secrets, reveals myriads of information about its owner’s physical, psychological, emotional and cognitive state. In the last century, scientists in the medical field achieved huge leaps in identifying, collecting and analysing of signals generated inside the human brain and body.The advancement in the technology of sensing and collecting those physiological signals has finally matured enough; making the mysterious human body a more attainable source of information to regular non-trained users. Research in the field of Human Computer Interaction has always looked for new ways to interface between humans and machines.With the help of physiological sensing, a new channel of information originating inside the human body becomes available. The opportunities this new channel provides are limitless. In this thesis we take this opportunity to look at our own bodies as a source of information, to better understand ourselves, and others. In a world where partners and friends are in long-distance relationships, meeting rooms are distributed over cities, and working teams are remote, efficient communication mediated over a distance becomes crucial. We see our bodies as a direct interface for communication: our heartbeats reveal how excited we are, our brain reveals how focused we are, and our skin reveals how stressed we are. How can we use this information to create an implicit communication channel between people? Can we increase empathy, connectedness, and awareness, if we include the body as a source of information in our communication systems? What are the ethical and social implications of this type of novel sensing and sharing of information? These are some of the questions this thesis is concerned with. The field of Computer Mediated Communication (CMC) has a long rich history. In this work, we extend on the means of mediating communication to include the body at the source, and the sink, of a communication system. Through a user-centred design process, we first start with a requirements gathering stage in which we investigate the expectations of users towards implicit physiological sensing and sharing of information. We build on top of existing CMC concepts to include bio-signals of the human body within communication.We chart our view of an extensive design space that includes implicit sensing opportunities and dimensions that consider new trends in communication including the distribution and remoteness of users. Through a set of research probes, ordered by one dimension of our extended design space, namely the number of senders and receivers, we explore how signals from the human body can be collected, visualized, and communicated. Starting with self-reflection as a form of communication, we look into how the revealing of information about one’s own body to oneself can enhance their understanding and interaction with systems in different contexts. Using electroencephalography signals from the frontal lobe of the brain, we build a system that aims to aid information workers in understanding how their attention varies during different tasks, and aids in scheduling and increased awareness. In a second research probe, we investigate the effect of revealing affective valence information collected through heart rate and electroencephalography to car drivers and its impact on driving performance. Looking at one-to-one personal communication, comprising the bigger part of our 21st century relationships, we develop two probes which use intimate information collected from the human body to enhance empathy, awareness and connectedness. We explore ways to visualize and communicate heart rate in online chat scenarios and how users deal with such an intimate yet ambiguous source of information. In another probe we introduce the idea of, not only implicitly sensing emotions as an input from one sender, but also using an actuating component at the output side of the communication channel. We explain and develop our concept of embodied emotion actuation using electroencephalography on one side and electrical muscle stimulation on the receiver’s side to enhance the connection between communicating partners. Communication in the large, with multiple senders and receivers who may be distributed or collocated over time and place, is the subject of our final set of research probes. Here we explored the area of audience sensing using physiological sensors to provide feedback to presenters or stakeholders. In two probes we investigated the use of electroencephalography to collect feedback from multiple audiences, in collocated, or distributed scenarios. In one probe, presenters can view real-time or post-hoc feedback to their presented material to evaluate and enhance it. In the second probe, visitors in a museum can implicitly rate their interest in exhibits which can be used by museum curators for better understanding of their audience. Finally, throughout our developed and evaluated research probes we reflect back on the design space presented in the beginning. We derive implications and recommendations for design as well as a conceptual architecture for physiologically augmented communication. We dedicate a discussion to the ethical and social implications of implicit physiological communication derived through our field and lab evaluations of our developed probes.We conclude with a vision of computer mediated communication for the next 20 years and discuss opportunities of future work.

    3D User Interfaces for Interventional Support and Medical Education
    (2018) Saalfeld, Patrick
    Spatial user interfaces hold the opportunity to improve the interaction with medical structures in several domains. This thesis presents spatial input and output devices as well as interaction techniques that support physicians during interventions, students and teachers in medical education, and patients and physicians during patient education. Physicians are supported with freehand gestures that are used as a touchless interaction technique to control interventional imaging software. This enables them to investigate patient’s radiographic scans during interventions in a sterile manner. Patient education, medical teaching and therapy planning are supported with the natural interaction technique of sketching. Here, approaches are presented to sketch vascular structures, pathologies, treatment options and blood flow in real-time, either as 2D or 3D structures. For this purpose, an interactive whiteboard and a spatial input and output device is used (namely the zSpace). Furthermore, this thesis presents general guidelines for the evaluation of interactive medical visualizations. This comprises quantitative and qualitative methods, directives for the collection of data, the definition of tasks and experimental designs as well as the selection of appropriate statistical tests. The conducted evaluations within this thesis follow these guidelines, which allows to assess them with quantitative and qualitative aspects. The presented prototypes show the potential for touchless interaction with medical image data, the chance to support patients in understanding the impact of different treatment strategies, and the opportunity in helping students to learn particularities and spatial relationships of vascular configurations.

    (2008) Bade, Ragnar
    Computerunterstützte Interventionsplanung für chirurgische Eingriffe kann die Qualität, Quantität und auch Machbarkeit komplizierter Eingriffe verbessern. Computerunterstützung erfolgt dabei bei der Bildaufnahme mit modernen CT- und MRT-Geräten, der Analyse und Extraktion von Informationen aus den aufgenommenen Bilddaten, der angemessenen Visua- lisierung und Präsentation dieser Daten sowie bei der Therapieentscheidungsfindung, zum Beispiel durch Abschätzung und Simulation von zu erwartenden Therapieergebnissen. Herausforderungen für die Computerunterstützung stellen unter anderem die Reduktion von Artefakten aus Bildaufnahme und Bildanalyse sowie die standardisierte dynamische Visua- lisierung patientenspezifischer Bilddaten dar. Im Rahmen dieser Arbeit werden Techniken zur Extraktion von qualitativ hochwertigen Oberflächenmodellen für die Visualisierung der durch Bildanalyse gewonnenen dreidimensionalen Patientenanatomie untersucht sowie Techniken zur standardisierten dynamischen Präsentation und effizienten interaktiven Exploration der dreidimensionalen Daten analysiert. Darauf aufbauend werden zwei effiziente Verfahren für die aufgabenangepasste Extraktion von Oberflächenmodellen aus Bildanalyseergebnissen entwickelt. Weiterhin werden Interaktionstechniken zur effizienten Exploration der dreidimensionalen Patientenanatomie evaluiert und es wird ein skriptbasiertes Verfahren zur Unterstützung der interaktiven Exploration und zur Erzeugung standardisierter dynamischer Visualisierungen vorgestellt. Abschließend werden alle erarbeiteten Methoden, Techniken und Erkenntnisse in der Konzeption und Entwicklung eines Lernsystems für die chirurgische Interventionsplanung in der Leberchirurgie zusammengeführt.

    Extending head-up displays: exploring the potential of large & 3D automotive windshield displays
    (2018) Häuslschmid, Renate
    Drivers consume an increasing amount of information while driving. The information is accessed on the in-car displays but also on personal devices such as the smartphone. Head-up displays are designed for a safe uptake of additional visual information while driving but their benefits are limited by the small display space. This motivates academia and industry to advance the head-up to the so-called windshield display. A windshield display will provide an extended display space, which largely or entirely covers the driver’s visual field through the windshield, as well as 3D and depth perception. Technologically, they are not yet feasible, but, thanks to steady advancements they will become available in the future. Extending a small 2D to a large 3D space requires a rethinking of the entire user interface. The windshield display opens up new opportunities for the type and amount of information, as well as for the way it is presented – ranging up to full augmented reality but it also raises concerns about a distracted driver. The core question of this thesis is whether such an extension is reasonable and desirable – meaning if there are convincing arguments and use cases which justify the potential risk of distraction. This thesis presents our research about the risks and benefits of the transition from a head-up to a windshield display. Thus, we explore the potentials and examine the safety risks and benefits as well as the drivers’ satisfaction of various display aspects. We developed a design space that shows how the new size and depth possibilities create new, or interrelate with existing, design factors. New design opportunities arise and suggest a redesign of existing functionality but also the integration of new content. We researched the information content that could be displayed on a windshield display and asked drivers what content they need and personally desire. We thereby obtained an extensive list of use cases and applications. We approached the question of where such content should be displayed, given the large 3D space. To enable the design of safe interfaces, we first examined the driver’s visual perception across the windshield and identified locations that promote information recognition, particularly in the new peripheral area. Simultaneously, we examined the different ways of placing and stabilizing the content. We compared the traditional screen-fixed with world-fixed (augmented reality) and head-stabilized placement methods in terms of user satisfaction, understandability and safety. The gained knowledge about the locations that support information uptake and about the best ways of placing content was merged into a layout concept that subdivides the driver’s view into several information areas. We also incorporated the drivers’ preferences into this design process and compared their personalized layouts with our vision-based layout concept. We assessed the safety of both layout versions and present a revised concept. We close this thesis by reflecting on other trends that may interrelate with the windshield display, namely autonomous driving and augmented reality consumer devices. We look at recent advancements in realizing windshield displays and endeavor a prediction of future developments in this area.

    Interactive advertising displays: audience behavior around interactive advertising columns, life-size screens and banner displays
    (2018) Beyer, Gilbert
    Interactive public displays are the latest development in the field of out-of-home advertising. Throughout history characteristic shapes for billboards evolved such as flat rectangular displays, long displays or cylindrical advertising columns. This work presents novel interactive display designs that are based on these historical role models and allow passers-by to interact with them in a natural, touchless manner. It further pursues a vision where interactive public displays become more active themselves and actively influence passer-by behavior in order to increase their effectiveness, better attract attention and improve public interaction in front of them. First, to overcome the challenge that passers-by often do not expect public displays to be interactive and thus pay no attention to them, this work presents a solution called unaware initial interaction that surprises passers-by and communicates interactivity by giving visual feedback to their initial movements. To be effective, the visual feedback has to be designed considering the specific display shapes, their requirements to contents and the typical approaching trajectories. Second, to overcome the challenge that larger groups of passers-by often crowd together in front of wide public displays or do not take optimal positions for interaction, this work presents a solution to subtly and actively guide users by dynamic and interactive visual cues on the screen in order to better distribute them. To explore these concepts and following an initial analysis of the out-of-home domain and of typical display qualities, interactive counterparts to the classical display shapes are designed such as interactive advertising columns, long banner displays and life-size screens. Then interactive contents and visual feedbacks are designed which implement the presented interactivity concepts, and audience behavior around them is analyzed in several long-term field studies in public space. Finally the observed passer-by and user behavior and the effectiveness of the display and content designs are discussed and takeaways given that are useful for practitioners and researchers in the field of public interaction with out-of-home displays.

    Gestaltungsempfehlungen für mehrbenutzerfähige Informationsanwendungen auf interaktiven Wandbildschirmen im (halb-)öffentlichen Raum
    (2018) Nutsi, Andrea
    Große mehrbenutzerfähige Wandbildschirme sind bereits seit den 1980er Jahren ein Forschungsthema. Damals noch auf wenige Prototypen beschränkt, sind große multi-touch Wandbildschirme durch den technologischen Fortschritt und sinkende Preise mittlerweile weithin verfügbar und in Forschung und Industrie verbreitet. Aufgrund ihrer Größe können zwei oder mehr Personen koloziert und gleichzeitig damit interagieren. Diese Mehrbenutzerfähigkeit stellt Forscher und Designer dieser Anwendungen vor besondere Herausforderungen, denn es müssen nicht nur Elemente aus dem Bereich der Mensch-Maschine-Interaktion berücksichtigt werden, sondern auch aus dem Bereich der Mensch-Mensch-Interaktion. Gerade im halb-öffentlichen oder öffentlichen Raum stehen die Entwickler solcher Anwendungen vor ganz anderen Herausforderungen als bei der Einzelnutzung im Desktopbereich, da sich Benutzer dieser Öffentlichkeit bewusst sind und sozialer Druck sowie soziale Verlegenheit entstehen können. Dennoch oder gerade deshalb ist es lohnenswert sich mit der Mehrbenutzerinteraktion zu beschäftigen, da sie soziale Interaktion anregen kann und soziales Lernen sowie ein soziales Erlebnis ermöglicht. Mit einem gestaltungsorientierten Forschungsansatz wird im Rahmen dieser Dissertation der Frage nachgegangen wie Informationsanwendungen auf interaktiven Wandbildschirmen im (halb-)öffentlichen Raum gestaltet sein müssen, um mehrbenutzerfähig zu sein. Zur Beantwortung dieser Forschungsfrage wurden insgesamt sieben Laborstudien durchgeführt, davon zwei zur Gegenüberstellung der Nutzung einer Anwendung durch eine Einzelperson vs. zwei Personen. Die übrigen Laborstudien fokussierten auf zwei Schwerpunktthemen, der Lesbarkeit und der Audioausgabe. Die Ergebnisse aus den Laborstudien werden mit Erkenntnissen aus der Literatur ergänzt und daraus Gestaltungsempfehlungen für mehrbenutzerfähige Informationsanwendungen auf interaktiven Wandbildschirmen im (halb-)öffentlichen Raum abgeleitet. Auf diese Gestaltungsempfehlungen können Forscher und Designer zukünftiger Wandbildschirmanwendungen aufbauen um diese mehrbenutzerfähig zu gestalten.

    Konzepte und Guidelines für Applikationen in Cinematic Virtual Reality
    (2020) Rothe, Sylvia
    Die meisten Menschen, die zum ersten Mal einen omnidirektionalen Film über ein Head-Mounted Display (HMD) sehen, sind fasziniert von der neuen Erlebniswelt. Das Gefühl, an einem anderen Ort zu sein, weit weg von der Realität, beeindruckt und lässt sie in eine andere Welt eintauchen. Die über Jahrzehnte entwickelte Filmsprache lässt sich nicht ohne Weiteres auf dieses neue Medium - Cinematic Virtual Reality (CVR) - übertragen. Der Betrachter kann die Blickrichtung und damit den sichtbaren Ausschnitt des Bildes frei wählen, und es ist deshalb nicht immer möglich, dem Zuschauer zu zeigen, was für die Geschichte wichtig ist. Herkömmliche Methoden für die Lenkung der Aufmerksamkeit - wie Nahaufnahmen oder Zooms - sind nicht ohne Weiteres verwendbar, andere – wie Bewegung und Farben – benötigen eine Evaluation und Anpassung. Um neue Konzepte und Methoden für CVR zu finden, sind neben den Forschungsergebnissen aus dem Filmbereich auch die anderer Forschungsgebiete, wie Virtual und Augmented Reality (VR und AR), relevant. Um geeignete Techniken der Aufmerksamkeitslenkung in CVR zu ergründen, werden in dieser Arbeit bekannte Methoden aus Film, VR und AR analysiert und eine einheitliche Taxonomie präsentiert. Dadurch ist es möglich, die verschiedenen Aspekte detaillierter zu untersuchen. Auch die Positionierung der Kamera kann nicht ohne Weiteres vom traditionellen Film auf CVR übertragen werden. Der Zuschauer nimmt bei der Betrachtung einer CVR-Anwendung in der virtuellen Welt die Position der Kamera ein. Dies kann zu Problemen führen, wenn die Kamerahöhe nicht seiner eigenen Körpergröße entspricht. Außerdem ist eine Auflösung einer Szene durch verschiedene Einstellungsgrößen nicht ohne Weiteres möglich, da dies für den Zuschauer ein Umherspringen in der virtuellen Welt bedeuten würde. In dieser Arbeit werden die Auswirkungen verschiedener Kamerapositionen auf den Zuschauer untersucht und Guidelines zur Kamerapositionierung vorgestellt. Die dazugewonnene Raumkomponente bietet neue Möglichkeiten. Schnitte müssen nicht unbedingt von der verstrichenen Zeit abhängen, sondern können auch auf der Blickrichtung des Betrachters basieren. In Übereinstimmung mit dem Begriff Timeline führen wir das Konzept der Spaceline für diese Methode der Story-Konstruktion ein. Während die Schnitte auf der Timeline vom Filmemacher festgelegt werden, bestimmt der Betrachter die Spaceline - innerhalb eines vom Filmemacher festgelegten Konstrukts. Durch diese individuelle Zuschauerführung ist es möglich, dass jeder seine eigene Geschichte in seinem eigenen Tempo und mit seinen eigenen Prioritäten entdeckt. Das Spaceline-Konzept bietet neue Interaktionsmöglichkeiten, die durch verschiedene Selektionstechniken umgesetzt werden können. Um Techniken zu finden, die für CVR geeignet sind, werden in dieser Arbeit blick- und kopfbasierte Ansätze untersucht. Auch wenn deren Wirksamkeit stark von den gewählten Parametern und physiologischen Faktoren abhängen, konnten wertvolle Erkenntnisse gewonnen werden, die in einen Design-Space für CVR-Konstrukte einfließen. Dieser Design-Space ermöglicht es beim Entwerfen einer CVR-Anwendung, die Attribute zu finden, die für die Anwendung am besten geeignet sind. Aber nicht nur die Entwicklung von CVR-Anwendungen stellt neue Herausforderungen. Durch das HMD ist ein Zuschauer von der restlichen Welt isoliert, und es bedarf neuer Methoden, um CVR als soziale Erfahrung erlebbar zu machen. Einige davon werden in dieser Arbeit vorgestellt und analysiert. Aus den gewonnenen Erfahrungen werden Empfehlungen für einen CVR-Movie-Player abgeleitet. Um die vorgestellten Konzepte und Guidelines zu entwickeln, wurden eine Reihe von Nutzerstudien durchgeführt, zum Teil mit Aufzeichnung der Kopf- und Blickrichtungen. Um diese Daten analysieren zu können, wurde ein Tool entwickelt, welches die Visualisierung der Daten auf dem Film ermöglicht. In dieser Arbeit werden Konzepte und Guidelines für verschiedene Felder in Cinematic Virtual Reality vorgestellt: Aufmerksamkeitslenkung, Kamerapositionierung, Montage, Zuschauererlebnis und Datenanalyse. Auf jedem dieser Gebiete konnten Erkenntnisse gewonnen werden, die auch für die andere Bereiche von Interesse sind. Oft hängen die Ergebnisse der einzelnen Fachgebiete zusammen und ergänzen sich gegenseitig. Ziel der Arbeit ist es, die verschiedenen Aspekte als Ganzes zu präsentieren.

    Affective automotive user interfaces
    (2020) Braun, Michael
    Technological progress in the fields of ubiquitous sensing and machine learning has been fueling the development of user-aware human-computer interaction in recent years. Especially natural user interfaces, like digital voice assistants, can benefit from understanding their users in order to provide a more naturalistic experience. Such systems can, for example, detect the emotional state of users and accordingly act in an empathic way. One major research field working on this topic is Affective Computing, where psycho-physiological measures, speech input, and facial expressions are used to sense human emotions. Affective data allows natural user interfaces to respond to emotions, providing promising perspectives not only for user experience design but also for safety aspects. In automotive environments, informed estimations of the driver’s state can potentially avoid dangerous errors and evoking positive emotions can improve the experience of driving. This dissertation explores Affective Automotive User Interfaces using two basic interaction paradigms: firstly, emotion regulation systems react to the current emotional state of the user based on live sensing data, allowing for quick interventions. Secondly, emotional interaction synthesizes experiences which resonate with the user on an emotional level. The constituted goals of these two interaction approaches are the promotion of safe behavior and an improvement of user experience. Promoting safe behavior through emotion regulation: Systems which detect and react to the driver’s state are expected to have great potential for improving road safety. This work presents a model and methods needed to investigate such systems and an exploration of several approaches to keep the driver in a safe state. The presented methods include techniques to induce emotions and to sample the emotional state of drivers. Three driving simulator studies investigate the impacts of emotionaware interventions in the form of implicit cues, visual mirroring and empathic speech synthesis. We envision emotion-awareness as a safety feature which can detect if a driver is unfit or in need of support, based on the propagation of robust emotion detection technology. Improving user experience with emotional interaction: Emotional perception is an essential part of user experience. This thesis entails methods to build emotional experiences derived from a variety of lab and simulator studies, expert feedback, car-storming sessions and design thinking workshops. Systems capable of adapting to the user’s preferences and traits in order to create an emotionally satisfactory user experience do not require the input of emotion detection. They rather create value through general knowledge about the user by adapting the output they generate. During this research, cultural and generational influences became evident, which have to be considered when implementing affective automotive user interfaces in future cars. We argue that the future of user-aware interaction lies in adapting not only to the driver’s preferences and settings but also to their current state. This paves the way for the regulation of safe behavior, especially in safety-critical environments like cars, and an improvement of the driving experience.
