- KonferenzbeitragUsability and UX of a Gaze Interaction Tool for Front Seat Passengers(Mensch und Computer 2019 - Tagungsband, 2019) Schmidbauer-Wolf, Gina Maria; Guder, MarkusInput modalities in general as well as in cars are evolving very fast (regarding) in terms of their spread and reliability. One possible input technique would be gaze interaction, a topic still being researched/ that is yet to be researched. There are currently no data available as regards the opinion of front seat passengers as potential users. What are the front seat passengers’ feelings towards gaze interaction, are they comfortable using it and do they think it is necessary? In order to provide a first insight into this subject matter, a laboratory experiment was conducted with 13 student participants, using a driving simulator. Qualitative data was collected during and after the experiment through a semi-structured interview while quantitative data was collected through questionnaires (ATI, CTAM, SUS). Since the system was mocked up and not implemented and the group of participants wasn’t heterogenous enough, the results of the study, which are slightly positive, only are a hint towards the actual answer.
- KonferenzbeitragUnpacking a model: An interactive visualization of a text similarity algorithm for legal documents(Mensch und Computer 2019 - Tagungsband, 2019) Soroko, Daria; Ndöge, Nina; Al-Shafeei, Ahmed; Heuer, HendrikThis paper presents a functional prototype for an interactive web-based interface i_sift developed to foreground the decision-making process of an algorithm that detects similarities in legal texts through word embeddings. Using this as a case study in Computational Social Science, our goal is, first, to highlight the importance of making computational tools and methods transparent to social scientists. Secondly, we suggest an approach that accomplishes this using methods and principles from Interactive Machine Learning and the Algorithmic Experience framework.
- KonferenzbeitragIntegration dialogbasierter Produktberater in Filtersysteme(Mensch und Computer 2019 - Tagungsband, 2019) Kleemann, Timm; Ziegler, JürgenZur Unterstützung der oft komplexen Produktsuche im Internet werden heute unterschiedliche Techniken wie Suchfunktionen oder Empfehlungskomponenten eingesetzt. Als recht erfolgreich haben sich facettierte Filtersysteme erwiesen, die die Ergebnismenge sukzessive entsprechend den gesetzten Filtereinstellungen eingrenzen. Diese Methode setzt allerdings klare Zielvorstellungen und Domänenkenntnisse seitens der Nutzer voraus. Als Alternative haben in der letzten Zeit konversationale Produktberater an Bedeutung gewonnen, die anhand einer Folge von Fragen geeignete Produkte selektieren, wobei die Fragen eher von den den Aufgaben und Anwendungszenarien der Nutzer als von den technischen Eigenschaften der Produkte ausgehen. Allerdings mangelt es gegenwärtig noch an Ansätzen, die Filtersysteme und konversationale Berater in sinnvoller und eng gekoppelter Weise integrieren. In dieser Arbeit wird ein integrierter Ansatz vorgestellt, bei dem Nutzer wahlfrei zwischen Filtersystem und Beratungsdialog wechseln können, wobei sich Auswahlaktionen in einer Komponente in konsistenter und transparenter Weise auf die andere Komponente auswirken und dort weiter angepasst werden können. Hierdurch sollen Nutzer mit unterschiedlichen Kenntnisgraden zum betreffenden Produkttyp besser unterstützt werden. Wir beschreiben die aus unserem Ansatz resultierenden Anforderungen an solche integrierten Systeme und berichten über eine Nutzerstudie, in der das Nutzerverhalten und die subjektive Bewertung an einer prototypischen Umsetzung untersucht wurde.
- KonferenzbeitragAugmented-Reality-Assisted Comparison of Physical Products(Mensch und Computer 2019 - Tagungsband, 2019) Álvarez Márquez, Jesús Omar; Ziegler, JürgenAugmented reality technology has experienced great improvement in recent years and it has been successfully applied to industry and entertainment settings. However, its application in everyday contexts such as shopping is still very limited. One of the requirements to seamlessly incorporate augmented reality into everyday tasks is to find intuitive, natural methods to make use of it. Due to the inherent capabilities of augmented reality to work as a visual aid to explore and extend the knowledge a user has of the surroundings, this paper proposes the combination of AR technology and product advisors in a novel approach for product comparison. The user's awareness of the differences between multiple physically present objects is enhanced through virtual augmentations, supporting an intuitive way of comparing two or more products while shopping. To assess the validity of the concept, a prototype for an AR-based shopping assistant for comparing vacuum cleaners has been implemented and evaluated in a user study, testing different methods of visual comparison and interaction.
- KonferenzbeitragUser Preferences of Voice Controlled Smart Light Systems(Mensch und Computer 2019 - Tagungsband, 2019) Faltaous, Sarah; El Jaki, Salma; Schneegass, StefanThe use of smart home devices is widely spreading. Several ways exist to control such devices. Besides classical approaches such as buttons and remote controls, voice user interfaces (VUIs) are showcased as a primary input method in the context of smart home. Yet, few studies investigated the user’s behaviour and experience with such newly offered input techniques. In this research, we carried out a field study to investigate the user preferences in using a VUIs for controlling a smart lighting system. The results indicate that the usage frequency drops after the first days and that users tend to use the system mainly once in the evening.
- KonferenzbeitragA Mixed Reality Application for Linked Data in Engineering and Production(Mensch und Computer 2019 - Tagungsband, 2019) Schilling, Katrin; Stanetzky, Daniel; Brecher, ChristianDuring the engineering and production process, numerous data and models are generated. As Digital Twin they form a virtual representation of the physical objects with their different views and characteristics. The contents spread over various disciplines, stakeholders and life cycle phases; they form a huge space of linked data and resources. Visualizing this information space is challenging, especially as it is closely related to the physical process and the manufacturing environment. Interaction technologies such as Mixed Reality (MR) offer an alternative to the traditional screen-based systems, that are still common in automation technology. The presented demo shows a spatial interface for the MR glasses HoloLens to explore various data resources in the context of a manufacturing cell. The user can view and interact with the content (such as media, documents, live data, functionalities) as a spatial graph. He can see the real and the digital resources at the same time, interact with those objects and control the machine as well.
- KonferenzbeitragStrukturierung interaktiver Styleguides(Mensch und Computer 2019 - Tagungsband, 2019) Müßiggang, Marcel; Rasim, Tim; Mentler, Tilo; Herczeg, MichaelUm Konsistenz und Gebrauchstauglichkeit bei der Entwicklung interaktiver Systeme zu fördern, wurden immer wieder Styleguides als unterstützende Werkzeuge empfohlen. In der Praxis findet ihre konsequente Einführung und Verwendung jedoch nur selten statt. Während frühere Forschungsarbeiten die Relevanz von Styleguides für menschzentriertes Design betonen, wurde die Gebrauchstauglichkeit der Styleguides selbst in geringerem Maße berücksichtigt. Ein wichtiger Aspekt dabei ist die Strukturierung von Styleguides, um den unkomplizierten Erhalt von bereitgestellten Informationen und Design-Elementen für Nutzende zu gewährleisten. Basierend auf den Ergebnissen einer Card-Sorting-Studie werden Gestaltungsprinzipien zur Strukturierung von interaktiven Styleguides vorgestellt und diskutiert.
- KonferenzbeitragPreparing and guiding forensic crime scene inspections in virtual reality(Mensch und Computer 2019 - Tagungsband, 2019) Süncksen, Matthias; Hamester, Frederik; Ebert, Lars; Teistler, MichaelComputer-based scene reconstruction is a method for answering specific forensic questions in the context of accident or crime scenes. For the resulting 3D reconstruction, the use of virtual reality (VR) technology is a novel presentation form. For the presentation to a prosecutor, the need to put visible content into context awards special significance to the moderator, especially as in a VR presentation the head mounted display (HMD) cuts VR users off from their natural environment. We analyze use cases for the parties involved in the courtroom VR presentation and consider the author, moderator and spectator roles and their corresponding session types for creating, directing and watching the presentation. A prototype system has been implemented to allow for suitable VR interactions for the three roles. An evaluation of the system with 12 participants assuming the role of the spectator yielded positive results with regard to the user experience and utility.
- KonferenzbeitragLearning Patient Transfers with Technology: A Qualitative Investigation of the Design Space(Mensch und Computer 2019 - Tagungsband, 2019) Dürr, Maximilian; Pfeil, Ulrike; Müller, Jens; Borowski, Marcel; Gröschel, Carla; Reiterer, HaraldNurses who care about patients with functional disabilities are frequently required to transfer a patient from one place to another. To prevent nurses from injuring themselves during patient transfers, many government-supported schools in Germany provide programs which teach how to conduct transfers based on the kinaesthetics care conception. However, the program is typically limited to merely three lectures. With the goal of promoting nurses' health behavior, we analyzed current practices in kinaesthetics education and explored how interactive technology can extend those practices. We interviewed nursing-care teachers (N = 5) and students (N = 27), and conducted four contextual inquiries during kinaesthetics course sessions. A qualitative analysis of the data revealed three themes. Based on these, we describe a set of implications to support the learning of kinaesthetics-based transfers by means of technology. We propose the use of the implications as initial design goals for user-centered design processes and exemplify their application by illustrating a concept for a tablet-based learning system.
- KonferenzbeitragSensorstation(Mensch und Computer 2019 - Tagungsband, 2019) Denefleh, TeresaDas Internet der Dinge (IoT) ist im Zuhause angekommen. Verspricht es doch mehr Sicherheit, Komfort und Unterhaltung in Wohnungen und Häuser zu bringen. In die Entwicklung solcher Smart Home/IoT-Anwendungen werden Nutzer kaum einbezogen. Wie diese funktionieren bleibt für sie meist verborgen. Dabei stellt die zunehmende Verbreitung von IoT-Anwendungen Wirtschaft und Wissenschaft vor schwerwiegende Fragen zur Beziehung zwischen Mensch und Maschine und deren Auswirkungen. Um zu verstehen, wie Menschen Sensoren verwenden und welche Auswirkungen diese auf gemeinschaftliches Leben haben können, wurde ein innovatives Forschungswerkzeug namens »Sensorstation« entwickelt, welches anschließend in einer mehrwöchigen empirischen Studie mit Menschen in ihrem Zuhause eingesetzt wurde. Im Rahmen dieser interaktiven Demo wird die Sensorstation den Besuchern präsentiert. Diese können dann selbstständig und ohne technisches knowhow schnell und einfach Sensoranwendungen entwickeln und live testen.
