TL;DR: In this paper , the authors conducted a need-finding study featuring 14 surveyed participants, each with sufficient years of experience, to uncover the current status of AR being used in industrial tomography, and showed that the potential of AR in this domain was positively rated by the participants.
Abstract: Augmented Reality (AR) has grown into a well-established technique with a compelling potential for interactive visualization. In spite of its clear potential, this novel tool has not yet been widely embraced as an industrial solution. In this paper, we address AR for a specific domain: industrial tomography. Within this domain, we conducted a need-finding study featuring 14 surveyed participants, each with sufficient years of experience. A systematic survey study was designed as the main body of our approach. Using this survey, we collected answers helping us to establish findings and formulate novel insights. The study as a whole consisted of a pilot and a formal study for better robustness. Our findings uncovered the current status of AR being used in industrial tomography, and showed that the potential of AR in this domain was positively rated by the participants. Based on our findings, we present key challenges and propose potential for interdisciplinary synergies between AR and industrial tomography.

TL;DR: In this article , a mixed-methods research study (N=56) was carried out on reported user perception of a sonified domestic flying robot with three sound conditions at three distances.
Abstract: When flying robots are used in close-range interaction with humans, the noise they generate, also called consequential sound, is a critical parameter for user acceptance. We conjecture that there is a benefit in adding natural sounds to noisy domestic drones. To test our hypothesis experimentally, we carried out a mixed-methods research study (N=56) on reported user perception of a sonified domestic flying robot with three sound conditions at three distances. The natural sounds studied were respectively added to the robot’s inherent noises during flying; namely a birdsong and a rain sound, plus a control condition of no added sound. The distances studied were set according to proxemics; namely near, middle, and far. Our results show that adding birdsong or rain sound affects the participants’ perceptions, and the proxemic distances play a nonnegligible role. For instance, we found that participants liked the bird condition the most when the drone was at far, while they disliked the same sound the most when at near. We also found that participants’ perceptions strongly depended on their associations and interpretations deriving from previous experience. We derived six concrete design recommendations.

TL;DR: Zhang et al. as mentioned in this paper proposed an AR approach providing visual and audio hints along with gaze-assisted instant post-task feedback for search tasks based on mobile head-mounted display (HMD).
Abstract: Augmented reality (AR) is emerging in visual search tasks for increasingly immersive interactions with virtual objects. We propose an AR approach providing visual and audio hints along with gaze-assisted instant post-task feedback for search tasks based on mobile head-mounted display (HMD). The target case was a book-searching task, in which we aimed to explore the effect of the hints together with the task feedback with two hypotheses. H1: Since visual and audio hints can positively affect AR search tasks, the combination outperforms the individuals. H2: The gaze-assisted instant post-task feedback can positively affect AR search tasks. The proof-of-concept was demonstrated by an AR app in HMD and a comprehensive user study (n=96) consisting of two sub-studies, Study I (n=48) without task feedback and Study II (n=48) with task feedback. Following quantitative and qualitative analysis, our results partially verified H1 and completely verified H2, enabling us to conclude that the synthesis of visual and audio hints conditionally improves the AR visual search task efficiency when coupled with task feedback.

TL;DR: In this article , the first systematic AR approach using optical see-through (OST) head mounted displays (HMDs) with comparative evaluation for domain users towards IPT visualization analysis was proposed.
Abstract: Industrial process tomography (IPT) is a specialized imaging technique widely used in industrial scenarios for process supervision and control. Today, augmented/mixed reality (AR/MR) is increasingly being adopted in many industrial occasions, even though there is still an obvious gap when it comes to IPT. To bridge this gap, we propose the first systematic AR approach using optical see-through (OST) head mounted displays (HMDs) with comparative evaluation for domain users towards IPT visualization analysis. The proof-of-concept was demonstrated by a within-subject user study (n=20) with counterbalancing design. Both qualitative and quantitative measurements were investigated. The results showed that our AR approach outperformed conventional settings for IPT data visualization analysis in bringing higher understandability, reduced task completion time, lower error rates for domain tasks, increased usability with enhanced user experience, and a better recommendation level. We summarize the findings and suggest future research directions for benefiting IPT users with AR/MR.
TL;DR: In this article , a systematic literature review of state-of-the-art ways AR can facilitate maritime collaboration is presented, which suggests that research focuses on bringing promising AR applications to higher technology readiness levels, applying robust evaluation methods, and grounding more on human factors like decision-making, situation awareness, and communication.
Abstract: Augmented Reality (AR) could improve maritime collaboration by facilitating human factors like situation awareness and decision-making. However, it is not clear in which ways AR can be beneficial and for which maritime operations. This paper addresses the need for a systematic literature review of state-of-the-art ways AR can facilitate maritime collaboration. Following the PRISMA statement, we searched for the constructs “AR,” “maritime operation,” and “collaboration” in the Web of Science and IEEE Xplore databases. Out of 691 search results, we retained 32 publications for analysis. Ten publications from other sources were included. Our results provide a review of AR applications for the maritime operations of ship navigation, personal navigation, maritime construction, maritime maintenance and inspection, and other. We suggest that research focuses on bringing promising AR applications to higher technology readiness levels, learning from other industries, applying robust evaluation methods, and grounding more on human factors like decision-making, situation awareness, and communication.

TL;DR: HybridMingler as discussed by the authors provides both on-site and remote attendees with a spatial sense of co-location in the very same venue location, thus ultimately improving perceived presence, and is a distributed mixed-reality system supporting ambient awareness and allowing both on site and remote conference attendees to virtually mingle.
Abstract: Mingling, the activity of ad-hoc, private, opportunistic conversations ahead of, during, or after breaks, is an important socializing activity for attendees at scheduled events, such as in-person conferences. The Covid-19 pandemic had a dramatic impact on the way conferences are organized, so that most of them now take place in a hybrid mode where people can either attend on-site or remotely. While on-site attendees can resume in-person mingling, hybrid modes make it challenging for remote attendees to mingle with on-site peers. In addressing this problem, we propose a collaborative mixed-reality (MR) concept, including a prototype, called HybridMingler. This is a distributed MR system supporting ambient awareness and allowing both on-site and remote conference attendees to virtually mingle. HybridMingler aims to provide both on-site and remote attendees with a spatial sense of co-location in the very same venue location, thus ultimately improving perceived presence.
TL;DR: In this paper , the authors examined the attentional mechanism of in-person collaboration by means of System Dynamics-based simulations using an eye tracking experiment and found that participants focused longer on key elements of the simulation than single users.
Abstract: This paper examines the attentional mechanism of in-person collaboration by means of System Dynamics-based simulations using an eye tracking experiment. Three experimental conditions were tested: in-person collaboration, remote collaboration, and single user. We hypothesized that collaboration focuses users’ attention on key information facilitating decision-making. Collaborating participants dwelt longer on key elements of the simulation than single users. Moreover, in-person collaboration and single users yielded a strategy of decision-making similar to an optimal strategy. Finally, in-person collaboration was less cognitively demanding and of higher quality. The contribution of this paper is a deeper understanding of how in-person collaboration on a large display can help users focus their visual attention on the most important areas. With this novel understanding, we believe collaborative systems designers will be better equipped to design more effective attention-guiding mechanisms in remote collaboration systems. The present work has the potential to advance the study of collaborative, interactive technologies.

TL;DR: In this article , the authors conducted a comparative study to explore the impact of virtuality and physicality in supporting human memorization through gamification and found that the virtuality outperformed the physicality.
Abstract: Augmented reality (AR) is evolving to become a pervasive tool for interacting with virtual objects. We conducted a comparative study to explore the impact of virtuality and physicality in supporting human memorization through gamification. A head-mounted display (HMD) AR memory matching game and a corresponding physical version game with paper boards were harnessed. The proof-of-concept version was demonstrated in an initial user study (n=12) with counterbalancing design to determine that our proposed gamified HMD AR system with virtuality could support better human memorization compared to the physical version game in reducing task time, improving usability, becoming more recommendable, and decreasing cognitive task workload. The study was then followed by quantitative analysis of the respective four metrics: game completion time (GCT), system usability scale (SUS), recommendation level, and NASA task load index (TLX). A brief qualitative analysis is presented. The results show that in our case, the virtuality outperformed the physicality in supporting human memorization in a gamified context through HMD AR in an evident range.

TL;DR: In this article , a speculative concept of assembling and eating biohybrid robots is introduced, with the intention to initiate cross-disciplinary and cross-cultural discussions around human-food interaction practices and related topics.
Abstract: What if animals were substituted with biohybrid robots? The replacement of pets with bioinspired robots has long existed within technological imaginaries and HRI research. Addressing developments of bioengineering and biohybrid robots, we depart from such replacement to study futures inhabited by animal-robot hybrids. In this paper, we introduce a speculative concept of assembling and eating biohybrid robots. With this provocation as a starting point, we intend to initiate cross-disciplinary and cross-cultural discussions around human-food interaction practices and related topics.
