- WorkshopbeitragApplication Scenarios for 3D-Printed Organ Models for Collaboration in VR & AR(Mensch und Computer 2019 - Workshopband, 2019) Muender, Thomas; Reinschluessel, Anke; Zargham, Nima; Döring, Tanja; Wenig, Dirk; Malaka, Rainer; Fischer, Roland; Zachmann, Gabriel; Schumann, Christian; Kraft, Valentin; Schenk, Andrea; Uslar, Verena; Weyhe, Dirk; Nopper, Hans; Lück, ThomasMedical software for computer-assisted surgery often solely supports one phase of the surgical process, e.g., surgery planning. This paper describes a concept for a system, which can be seamlessly used in the preoperative planning phase, in the intraoperative phase for viewing the planning data, as well as for training and education. A combination of virtual and augmented reality with a multi-user functionality will support the three phases. 3D-printed organ models will be used as interaction devices for more intuitive interaction with the visual data and for educating future surgeons. We present the three application scenarios for this concept in detail and discuss the research opportunities.
- KonferenzbeitragAudienceAR - Utilising Augmented Reality and Emotion Tracking to Address Fear of Speech(Mensch und Computer 2019 - Tagungsband, 2019) Hartl, Philipp; Fischer, Thomas; Hilzenthaler, Andreas; Kocur, Martin; Schmidt, ThomasWith Augmented Reality (AR) we can enhance the reality by computer-generated information about real entities projected in the user's field of view. Hence, the user's perception of a real environment is altered by adding (or subtracting) information by means of digital augmentations. In this demo paper we present an application where we utilise AR technology to show visual information about the audience's mood in a scenario where the user is giving a presentation. In everyday life we have to talk to and in front of people as a fundamental aspect of human communication. However, this situation poses a major challenge for many people and may even go so far as to lead to fear and and avoidance behaviour. Based on findings in previous work about fear of speech, a major cause of anxiety is that we do not know how the audience judges us. To eliminate this feeling of uncertainty, we created an AR solution to support the speaker while giving a speech by tracking the audience's current mood and displaying this information in real time to the speaker's view: AudienceAR. By doing so we hypothesise to reduce the speaker's tension before and during presentation. Furthermore, we implemented a small web interface to analyse the presentation based on the audience mood after the speech is given. Effects will be tested in future work.
- KonferenzbeitragAugmented Reality Based Recommending in the Physical World(Mensch und Computer 2018 - Workshopband, 2018) Álvarez Márquez, Jesús Omar; Ziegler, JürgenRecommender systems have received the attention of the scientific community for a long time now and they have become a daily tool for internet users. Nonetheless, they are not commonly applied to physical settings, where having access to recommendations could be of great benefit, specially when combined with item comparison capabilities. Due to the latest augmented reality technology advances, it is possible to bring these concepts together. An intuitive action like visually comparing two products could be enhanced by 3D cues and suggestions. In such terms, we discuss the possibilities to improve the item exploration and decision-making stages of the recommending process by providing item comparison supported by 3D augmentations, offering a novel contribution to both augmented reality and recommender systems domains.
- ZeitschriftenartikelAugmented Reality for Future Mobility: Insights from a Literature Review and HCI Workshop(i-com: Vol. 20, No. 3, 2021) Riegler, Andreas; Riener, Andreas; Holzmann, ClemensThere is a growing body of research in the field of interaction between drivers/passengers and automated vehicles using augmented reality (AR) technology. Furthering the advancements and availability of AR, the number of use cases in and around vehicles rises. Our literature review reveals that in the past, AR research focussed on increasing road safety and displaying navigational aids, however, more recent research explores the support of immersive (non-)driving related activities, and finally enhance driving and passenger experiences, as well as assist other road users through external human-machine interfaces (HMIs). AR may also be the enabling technology to increase trust and acceptance in automated vehicles through explainable artificial intelligence (AI), and therefore help on the shift from manual to automated driving. We organized a workshop addressing AR in automotive human-computer interaction (HCI) design, and identified a number of challenges including human factors issues that need to be tackled, as well as opportunities and practical usages of AR in future mobility. We believe that our status-quo literature analysis and future-oriented workshop results can serve as a research agenda for user interface designers and researchers when developing automotive AR interfaces.
- KonferenzbeitragAugmented Reality to Support Temporal Coordination of Spatial Dispersed Production Teams(Mensch und Computer 2018 - Workshopband, 2018) Kluge, Annette; Borisov, Nikolaj; Schüffler, Arnulf; Weyers, BenjaminThis work presents a prototypic system that uses augmented reality technology to support temporal coordination of spatial dispersed production team members. This system is used to investigate the potential benefit of augmented reality for temporal coordination. We will present a study design as well as various research questions to be considered in future work.
- 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.
- KonferenzbeitragComparison Between Video-mediated and Asymmetric 3D Teleconsultation During a Preclinical Scenario(Mensch und Computer 2021 - Tagungsband, 2021) Strak, Robin; Yu, Kevin; Pankratz, Frieder; Lazarovici, Marc; Sandmeyer, Benedikt; Reichling, Julia; Weidert, Simon; Kraetsch, Clemens; Roegele, Barbara; Navab, Nassir; Eck, Ulrich; Roth, DanielCurrent teleconsultation solutions for preclinical emergencies can transmit knowledge from a remote expert to a local paramedic using audio and 2D video channels. Such technology lacks precision and efficiency for medical diagnostic tasks, and visual feedback is often missing between participants. We investigate a mixed reality 3D teleconsultation solution for preclinical use, which provides a 3D reconstruction of the local scene to a remote expert, displayed in Virtual Reality. A remote expert can join the local scene virtually as an Augmented Reality avatar. The remote expert can annotate the local scene and guide the local paramedics through the procedure. We explored our system in a user study within a preclinical scenario on a collaborative task of attaching chest lead electrodes of a 12 channel electrocardiogram on a mannequin. We compared the 3D teleconsultation system to a 2D video-mediated teleconsultation via a top-mounted camera and report results from the consultee side in AR. Based on our empirical user study with 10 paramedics with an average of 17 years experience, we observe an improvement in the electrode placement quality using the 3D teleconsultation system. Results indicate no significant difference in the cognitive task-load between conditions. Participants perceived the video-mediated consultation as more usable due to their unfamiliarity with the 3D teleconsultation system. However, participants acknowledge the potential of 3D teleconsultation and believe such a system can significantly improve the preclinical treatment.
- TextdokumentA Discussion About Current Augmented Reality Concepts Which Help Users Better Understand and Manipulate Robot Behavior(INFORMATIK 2020, 2021) Groetenhardt, KaiFor a safer, more trustful, and more dynamic collaboration, humans should understand and be able to manipulate the behavior of robots they are interacting with. Therefore, a way for a meaningful communication has to be established that takes place in a common perceptual space. One way to accomplish that is to use augmented reality (AR) in which the robot is able to display information for the human in 3D space, and the human can send commands to the robot using interaction methods provided by AR devices. In this work, a brief overview of AR concepts is given and discussed. They are divided into three categories: (1) understanding the movement of robots, (2) understanding the internal states of robots, and (3) manipulating robot behavior. Whereas (1) and (2) already show a number of promising approaches, and (3) is still in need for more innovative ideas.
- KonferenzbeitragThe effects of consultant avatar size and dynamics on customer trust in online consultations(Mensch und Computer 2020 - Tagungsband, 2020) Brown, Gordon; Prilla, MichaelThis study investigates the impact of avatars on interactions between customers and consultants in remote, online consultations supported by Augmented Reality (AR). Based on past research, we were interested whether the appearance of an avatar and its dynamics affect important factors for online consultations such as social presence, trust in the consultant and perceived customer satisfaction. In particular, we chose avatar size and dynamics (movement/gaze) to compare different avatars in a 2x2 experiment, in which customers wear AR head mounted devices to consult a remotely located consultant in a mock furniture consultation session. Our results show no significant differences in trust and satisfaction, but significantly different levels of perceived social presence for life-sized, dynamic avatars as well as significantly higher co-presence for all life-sized avatars. Additional data from interviews with the participants revealed a clear preference for dynamic avatars over static ones. Based on an analysis of these findings, we make design recommendations and suggest directions for future research.
- KonferenzbeitragEffects of position of real-time translation on AR glasses(Mensch und Computer 2020 - Tagungsband, 2020) Rzayev, Rufat; Hartl, Sabrina; Wittmann, Vera; Schwind, Valentin; Henze, NielsAugmented reality (AR) provides users with contextually relevant multimedia content by overlaying it on real-world objects. However, overlaying virtual content on real-world objects can cause occlusion. Especially for learning use cases, the occlusion might result in missing real-world information important for learning gain. Therefore, it is important to understand how virtual content should be positioned relative to the related real-world information without negatively affecting the learning experience. Thus, we conducted a study with 12 participants using AR glasses to investigate the position of virtual content using a vocabulary learning task. Participants learned foreign words shown in the surrounding while viewing translations using AR glasses as an overlay, on the right or below the foreign word. We found that showing virtual translations on top of foreign words significantly decreases comprehension and increase users' task load. Insights from our study inform the design of applications for AR glasses supporting vocabulary learning.
