  [BibTeX] [Abstract] [Download PDF]

  3D printers are no longer found only in industry, universities or makerspaces but now are increasingly used in domestic settings. Personal fabrication will increase in the coming years, and 3D printing will play an important role in this process. Due to technology and price development, 3D printers are becoming established among casual users at home. However, there are still many hurdles in the use of 3D printers that interfere with their appropriation in everyday life. In this paper, we investigate how chatbots can overcome these hurdles and support onboarding to 3D printing. Furthermore, we explore how chatbots can be used as a human–machine interface and facilitate interaction with 3D printers for both novice and expert users. In a research-through-design approach, we have created a fully functional chatbot that introduces users to 3D printing and helps them perform typical tasks when operating 3D printers.

  Krings, K., Weber, P., Jasche, F. & Ludwig, T. (2022)FADER: An Authoring Tool for Creating Augmented Reality-Based Avatars from an End-User Perspective

  IN Mensch und Computer 2022 – Tagungsband doi:10.1145/3543758.3543778
  [BibTeX] [Abstract] [Download PDF]

  Although augmented reality (AR) is becoming more common in our society, there are few specialized end-user tools for appropriate AR content creation. Most tools are focused on creating entire 3D applications or require extensive knowledge in programming and 3D modeling. With reference to End-User Development (EUD), we present a design case study for an end-user-friendly authoring tool that allows domain experts to create individual AR avatars in the field of Human-Food Interaction. After reviewing current approaches and design guidelines, we designed and implemented FADER, a web-based tool for creating AR-based food avatars. Our evaluation shows that playful design fosters immersion, and that abstract placeholders and highly simplified controls empower non-developers to create AR content. Our study contributes to a better understanding of end-user needs and practices during the AR creation process and informs the design of future AR authoring tools.

  Hoffmann, S., Ludwig, T., Jasche, F., Wulf, V. & Randall, D. (2022)RetrofittAR: Supporting Hardware-Centered Expertise Sharing in Manufacturing Settings through Augmented Reality

  IN Computer Supported Cooperative Work (CSCW) doi:10.1007/s10606-022-09430-x
  [BibTeX] [Abstract] [Download PDF]

  Since almost the onset of computer-supported cooperative work (CSCW), the community has been concerned with how expertise sharing can be supported in different settings. Here, the complex handling of machines based on experience and knowledge is increasingly becoming a challenge. In our study, we investigated expertise sharing in a medium-sized manufacturing company in an effort to support the fostering of hardware-based expertise sharing by using augmented reality (AR) to ‘retrofit’ machines. We, therefore, conducted a preliminary empirical study to understand how expertise is shared in practice and what current support is available. Based on the findings, we derived design challenges and implications for the design of AR systems in manufacturing settings. The main challenges, we found, had to do with existing socio-technical infrastructure and the contextual nature of expertise. We implemented a HoloLens application called RetrofittAR that supports learning on the production machine during actual use. We evaluated the system during the company’s actual production process. The results show which data types are necessary to support expertise sharing and how our design supports the retrofitting of old machines. We contribute to the current state of research in two ways. First, we present the knowledge-intensive practice of operating older production machines through novel AR interfaces. Second, we outline how retrofitting measures with new visualisation technologies can support knowledge-intensive production processes.

  Over the last decades, different kinds of design guides have been created to maintain consistency and usability in interactive system development. However, in the case of spatial applications, practitioners from research and industry either have difficulty finding them or perceive such guides as lacking relevance, practicability, and applicability. This paper presents the current state of scientific research and industry practice by investigating currently used design recommendations for mixed reality (MR) system development. We analyzed and compared 875 design recommendations for MR applications elicited from 89 scientific papers and documentation from six industry practitioners in a literature review. In doing so, we identified differences regarding four key topics: Focus on unique MR design challenges, abstraction regarding devices and ecosystems, level of detail and abstraction of content, and covered topics. Based on that, we contribute to the MR design research by providing three factors for perceived irrelevance and six main implications for design recommendations that are applicable in scientific and industry practice.

  A variety of studies exist that design innovative interactions based on augmented reality (AR). Comparing them often involves examining their laboratory studies. However, since AR has a high context dependency (e.g., reference to the real environment), it is important to emphasize that existing literature do not reveal generalizable results regarding how to design AR instructions. Within this paper, we argue that it is time to open up new use cases and test appropriation mechanisms in practice with the help of long-term studies to build a base for the comparison of AR-based interactions. Such a repository built up with long-term studies has the potential to define valid insights for future developments in the AR environment.

  In view of its capacity to create physical objects for a wide range of different potential applications, 3D printing has become increasingly popular over the years. However, given its scope of application, 3D printing can be challenging. Novice users often need assistance from experts, who are not always available. Recent interest in the development of conversational agents opens up the possibility of assisting novice users in their interactions with 3D printers, thus improving their experience. In this paper, we illustrate a potential concept of a conversational agent and present a prototype of a Telegram chatbot to improve the user experience of 3D printing.

  Developing systems to support remote collaboration usually involves creating new environments in which non-co-located participants produce actions that are, at least in part, accessible to one another. However, this typically fractures the relationship between those actions and the sense of a shared environment, engendering difficulties that can render even the simplest of activities problematic. This becomes more pronounced as the activities become more complex and involve physical artifacts. Although mixed reality seems to offer promising ways of overcoming these troubles, there is still a risk of replicating the fractured ecology problem. We report on an empirical study and the development of a mixed reality prototype called BeamLite that seeks to bypass such issues by providing participants with the illusion of them sharing a single familiar place. Although our evaluation revealed possibilities for evading some troubles associated with artifact-focused remote collaboration, it exposed the need for virtual toolboxes that dynamically support specific work practices and the importance of virtual artifacts embedded within the physical environment to further diminish the sense of ecological fracture.

  Consumer purchase decisions are not only determined by the quality or price of a product. Customers also want an innovative product that they can identify with in something more than just a functional way. Much of this appeal is often bound up with the innovative character of a product. However, the global market and the huge variety of products available make it challenging for companies to help customers understand the particular innovations in their products, especially in terms of technical “hidden” innovations. Augmented reality (AR) offers interactive experiences in real-world environments through digitalized information. In this paper, we present a design case study about an AR-based approach to reveal the hidden innovations to potential users in an engaging and “emotional” way by using the example of a vacuum cleaner. Based on an empirical study, we designed and implemented the fully functional HoloLens application VacuumCleanAR, which allows users to discover the hidden innovations of a vacuum cleaner in a less functional and more consumer-centric way. This reveals the scope for augmenting other physical artifacts in a similar fashion.

  The increasing functionalities and close integration of hardware and software of modern cyber-physical systems present users with distinct challenges in applying and, especially, appropriating those systems within their practices. Existing approaches to design for appropriation and the development of sociable technologies that might support users seeking to understand how to make such technologies work in a specific practice, often lack appropriate user interfaces to explain the internal and environment-related behavior of a technology. By taking the example of 3D printing, we examine how augmented reality can be used as a novel human–machine interface to ease the way for hardware-related appropriation support. Within this paper we designed, implemented and evaluated a prototype called PrintARface, that extends a physical 3D printer by incorporating virtual components. Reflections upon the evaluation of our prototype are used to provide insights that foster the development of hardware-related appropriation support by encompassing augmented reality-based human–machine interfaces.

Within this paper we designed, implemented and evaluated a prototype called PrintARface, that extends a physical 3D printer by incorporating virtual components. Reflections upon the evaluation of our prototype are used to provide insights that foster the development of hardware-related appropriation support by encompassing augmented reality-based human–machine interfaces.},

  Jasche, F. & Ludwig, T. (2019)Appropriating 3D Printers in Augmented Reality

  Digital fabrication technologies, such as 3D printers, are receiving more and more attention, not only from professionals but also from hobbyists. However, even though people have easier access to these devices, 3D printers remain a black box for many users. To support the appropriation of 3D printers, this demonstration presents a system which extends a physical printer to include virtual components using augmented reality (AR). With these components, we try to explain how the printer works and allow the user to operate the printer through an AR application. We extend existing software with a custom solution to create a unique user interface and user experience. Our user interface provides a new way of inspecting models in AR before they are printed.

  Zusammenfassung In der heutigen Zeit sind Meetings nicht mehr physisch an einen Ort gebunden. Vor allem in der Wis-sensarbeit ergänzen Telefonate oder Skype-Konferenzen bereits seit langem klassische Face-to-Face-Meetings. Verschiedene Forschungsdiskurse, vor allem der computerunterstützten Gruppenarbeit, unter-suchen bereits seit nun mehr fast drei Jahrzehnten, wie durch den Einsatz von IT verteilte Gruppenarbeit in ihren verschiedensten Ausprägungen unterstützt werden kann. Mit zunehmender Leistungsfähigkeit von Technologien mit Fokus auf Augmented Reality (AR) sowie Virtual Reality (VR) sind neue Mög-lichkeiten hinzugekommen, die ein hohes Potential zur Unterstützung verteilter Meetings bieten. In die-sem Paper stellen wir einen Ansatz vor, der durch die Kombination von AR und VR ein Kommunikati-onssystem mit verschiedenen Kollaborationsmöglichkeiten zur geeigneten Unterstützung verteilter Meetings umsetzt und durch den Einsatz von Consumer-Hardware auch für die Arbeit von zu Hause geeignet ist. Der Mehrwert des Ansatzes liegt vor allem darin, dass auch solche Szenarien fokussiert werden, bei denen sich zwei oder mehr Personen in demselben Raum befinden sowie ein oder mehrere Personen nicht anwesend sind und entfernt zur selben Zeit kooperieren.

  Kirchhübel, J. & Jasche, F. (2018)BeamLite Nutzerzentrierte Konzeption, Implementierung und Evaluierung eines Mixed Reality Kommunikationssystems für Remote-Meetings (Masterarbeit)

  [BibTeX] [Abstract] [Download PDF]

  Studien zeigen, dass die Anzahl der Meetings im beruflichen Alltag zunimmt. Die räumliche Distribuierung von Arbeitern und Partnern erschwert es jedoch zunehmend Face-to-Face- Meetings abzuhalten. Tele- und Videokonferenzsysteme gehören daher zum Alltag vieler Angestellter und gewinnen zunehmend an Wichtigkeit für die Forschung [RN01]. Bei der Betrachtung unterschiedlicher Systeme fällt auf, dass die Vermittlung von Telepräsenz im Fokus steht. Entwickler und Forscher adressieren mit ihren Projekten die Frage „Wie bringe ich den Remote-Teilnehmer in das Meeting?“ Allerdings mangelt es an der Lösung zu der Fragestellung: „Wie kann das Meeting zu dem Remote-Teilnehmer gebracht werden?“ Die Masterarbeit BeamLite bearbeitet diese Fragestellung. Das Ziel besteht in der Entwicklung eines Konzepts für ein innovatives Mixed Reality-Kommunikationssystem, das sich neuer Technologien wie Virtual Reality und Augmented Reality bedient. Das System kann einem entfernten Teilnehmer eines Meetings die Möglichkeit bieten, sich virtuell an demselben Ort wie die lokalen Teilnehmer zu befinden und aktiv an diesem Meeting teilzunehmen. Der entfernte Teilnehmer kann den Meeting-Raum durch ein Virtual Reality-Headset so realitätsnah wie möglich wahrnehmen, sich in diesem bewegen und mit Objekten sowie Personen in der Umgebung interagieren. Zeitgleich werden Position, Sprache sowie Gestik des entfernten Teilnehmers an die Personen im realen Meeting-Raum mittels Augmentierung durch Datenbrillen übertragen.
