ABSTRACT: The help of a remote expert in performing a maintenance task can be useful in many situations, and can save time as well as money. In this context, augmented reality (AR) technologies can improve remote guidance thanks to the direct overlay of 3D information onto the real world. Furthermore, virtual reality (VR) enables a remote expert to virtually share the place in which the physical maintenance is being carried out. In a traditional local collaboration, collaborators are face-to-face and are observing the same artifact, while being able to communicate verbally and use body language, such as gaze direction or facial expression. These interpersonal communication cues are usually limited in remote collaborative maintenance scenarios, in which the agent uses an AR setup while the remote expert uses VR. Providing users with adapted interaction and awareness features to compensate for the lack of essential communication signals is therefore a real challenge for remote MR collaboration. However, this context offers new opportunities for augmenting collaborative abilities, such as sharing an identical point of view, which is not possible in real life. Based on the current task of the maintenance procedure, such as navigation to the correct location or physical manipulation, the remote expert may choose to freely control his/her own viewpoint of the distant workspace, or instead may need to share the viewpoint of the agent in order to better understand the current situation. In this work, we first focus on the navigation task, which is essential to complete the diagnostic phase and to begin the maintenance task in the correct location. We then present a novel interaction paradigm, implemented in an early prototype, in which the guide can show the operator the manipulation gestures required to achieve a physical task that is necessary to perform the maintenance procedure. These concepts are evaluated, allowing us to provide guidelines for future systems targeting efficient remote collaboration in MR environments.

Project description:BackgroundeHealth literacy is defined as the ability to seek, find, understand, and appraise health information from electronic sources and apply knowledge gained to addressing or solving a health problem. Previous research has shown high reliance on both online and face-to-face interpersonal sources when sharing and receiving health information.ObjectiveIn this paper, we examine these interpersonal sources and their interplay with respondents' eHealth literacy and perceived health outcomes. Specifically, we look at how the relationship between eHealth literacy and health outcomes is moderated by (1) finding help while performing online activities, (2) finding others with similar health concerns online, and (3) the importance of finding others with similar health concerns for people from ethnic minorities, specifically Palestinian citizens of Israel versus Israeli Jews.MethodsWe used a nationally representative random-digit dial telephone household survey of an Israeli adult population (age ?21 years, N=819). The collected data were analyzed using two regression models. The first examined how the correlation between eHealth literacy and perceived outcomes was moderated by the availability of help. The second examined how the correlation between eHealth literacy and perceived outcomes was moderated by finding others with similar health concerns and by ethnicity.ResultsRespondents with low eHealth literacy who were able to recruit help when performing online activities demonstrated higher perceived health outcomes compared to similar respondents who did not find help. Respondents with low eHealth literacy, who were able to find others with similar health concerns (online), demonstrated higher perceived health outcomes when compared to similar respondents who did not find others with similar health concerns. Finally, finding similar others online was more helpful in enhancing health outcomes for ethnic minorities; Palestinian citizens of Israel gained more health benefits by finding similar others compared to Israeli Jews.ConclusionsAlthough the availability of help and the notion of ethnicity have been discussed extensively within the context of social capital and health, our findings offer initial evidence for the relevancy of these concepts when studying individuals' eHealth literacy. Specifically, our findings enable a better understanding of the role of social ties and ethnicity in moderating the interplay between eHealth literacy and perceived health outcomes. Given the increased importance of eHealth information, our findings enhance understanding of how social ties can potentially compensate for low eHealth literacy.

Project description:ImportanceMixed-reality (MR) technology has the potential to enhance care delivery, but there remains a paucity of evidence for its efficacy and feasibility.ObjectiveTo assess the efficacy and feasibility of MR technology to enhance emergency care delivery in a simulated environment.Design, setting, and participantsThis pilot randomized crossover trial was conducted from September to November 2021 at a single center in a high-fidelity simulated environment with participants block randomized to standard care (SC) or MR-supported care (MR-SC) groups. Participants were 22 resident-grade physicians working in acute medical and surgical specialties prospectively recruited from a single UK Academic Health Sciences Centre. Data were analyzed from September to December 2022.InterventionParticipants resuscitated a simulated patient who was acutely unwell, including undertaking invasive procedures. Participants completed 2 scenarios and were randomly assigned to SC or MR-SC for the first scenario prior to crossover. The HoloLens 2 MR device provided interactive holographic content and bidirectional audiovisual communication with senior physicians in the MR-SC group.Main outcomes and measuresThe primary outcome was error rate assessed via the Imperial College Error Capture (ICECAP) multidimensional error-capture tool. Secondary outcomes included teamwork (Observational Teamwork Assessment for Surgery [OTAS]; range, 0-6 and Teamwork Skills Assessment for Ward Care [T-SAW-C]; range, 1-5), scenario completion, stress and cognitive load (NASA Task Load Index [NASA-TLX; range 0-100]), and MR device user acceptability.ResultsA total of 22 physicians (15 males [68.2%]; median [range] age, 28 [25-34] years) were recruited. MR technology significantly reduced the mean (SD) number of errors per scenario compared with SC (5.16 [3.34] vs 8.30 [3.09] errors; P = .003), with substantial reductions in procedural (0.79 [0.75] vs 1.52 [1.20] errors; P = .02), technical (1.95 [1.40] vs 3.65 [2.03] errors; P = .01), and safety (0.37 [0.96] vs 0.96 [0.85] errors; P = .04) domains. MR resulted in significantly greater scenario completion rates vs SC (22 scenarios [100%] vs 14 scenarios [63.6%]; P = .003). It also led to significant improvements in the overall quality of teamwork and interactions vs SC as measured by mean (SD) OTAS (25.41 [6.30] vs 16.33 [5.49]; P < .001) and T-SAW-C (27.35 [6.89] vs 18.37 [6.09]; P < .001) scores. As reported via mean (range) NASA-TLX score, there were significant reductions for MR-SC vs SC in participant temporal demands (38 [20-50] vs 46 [30-70]; P = .03) and significant improvements in self-reported task performance (50 [30-60] vs 39 [10-70]; P = .01). Overall, 19 participants (86.4%) reported that they were more confident in making clinical decisions and undertaking clinical procedures with MR support.Conclusions and relevanceThis study found that the use of MR technology reduced error, improved teamwork, and enhanced practitioner confidence when used to support the delivery of simulated emergency medical care.Trial registrationClinicalTrials.gov Identifier: NCT05870137.
