Collecting, coordinating, and synchronizing a large amount of data from multiple VR/AR hardware while maintaining a high framerate can be a daunting task, despite the compelling nature of multimodal data. The Lab Streaming Layer (LSL) is an open-source framework that enables the synchronous collection of various types of multimodal data, unlike existing expensive alternatives. However, despite its potential, this framework has not been fully adopted by the VR/AR research community. In this paper, we present a guideline of the LSL framework’s use in VR/AR research as well as report current trends by performing a comprehensive literature review on the subject. We extract 549 publications using LSL from January 2015 to March 2022. We analyze types of data, displays, and targeted application areas. We describe in-depth reviews of 38 selected papers and provide use of LSL in the VR/AR research community while highlighting benefits, challenges, and future opportunities.}, keywords = {2023, geriatric, patient, simulation, vgp, Virtual Human}, pubstate = {published}, tppubtype = {article} } @article{musa2023technology, title = {Technology Acceptance and Authenticity in Interactive Simulation: Experimental Study}, author = {Dahlia Musa and Laura Gonzalez and Heidi Penny and Salam Daher}, url = {https://mededu.jmir.org/2023/1/e40040/}, doi = {doi:10.2196/40040}, year = {2023}, date = {2023-02-15}, urldate = {2023-02-15}, journal = {Journal of Medical Education}, volume = {9}, pages = {e40040}, abstract = {Background: Remote and virtual simulations have gained prevalence during the COVID-19 pandemic as institutions maintain social distancing measures. Because of the challenges of cost, flexibility, and feasibility in traditional mannequin simulation, many health care educators have used videos as a remote simulation modality; however, videos provide minimal interactivity. Objective: In this study, we aimed to evaluate the role of interactivity in students’ simulation experiences. We analyzed students’ perceptions of technology acceptance and authenticity in interactive and noninteractive simulations. Methods: Undergraduate nursing students participated in interactive and noninteractive simulations. The interactive simulation was conducted using interactive video simulation software that we developed, and the noninteractive simulation consisted of passively playing a video of the simulation. After each simulation, the students completed a 10-item technology acceptance questionnaire and 6-item authenticity questionnaire. The data were analyzed using the Wilcoxon signed-rank test. In addition, we performed an exploratory analysis to compare technology acceptance and authenticity in interactive local and remote simulations using the Mann-Whitney U test. Results: Data from 29 students were included in this study. Statistically significant differences were found between interactive and noninteractive simulations for overall technology acceptance (P<.001) and authenticity (P<.001). Analysis of the individual questionnaire items showed statistical significance for 3 out of the 10 technology acceptance items (P=.002, P=.002, and P=.004) and 5 out of the 6 authenticity items (P<.001, P<.001, P=.001, P=.003, and P=.005). The interactive simulation scored higher than the noninteractive simulation in all the statistically significant comparisons. Our exploratory analysis revealed that local simulation may promote greater perceptions of technology acceptance (P=.007) and authenticity (P=.027) than remote simulation. Conclusions: Students’ perceptions of technology acceptance and authenticity were greater in interactive simulation than in noninteractive simulation.

We conducted a study to compare the software prototype to physical and 2-D image measurement techniques commonly used by clinicians. We compared inter-rater reliability between the techniques and measurements (i.e., length, width, depth, perimeter, and surface area). Results: Inter-rater reliability was good or excellent for the physical, image, and software measurement techniques; however, there were significant differences in measurements between the techniques. For complex measurements (i.e., perimeter and surface area), the reliability of the software exceeded that of the physical and image techniques. Conclusion: Although inter-rater reliability was high for all measurement techniques, there was significant variability between the techniques. The software was overall most reliable, especially for calculation of complex measurements.

Research questions were: (1) Does interactivity engage students in problem-solving more than non-interactivity? (2) Does interactivity increase the authenticity of decision-making more than non-interactivity? Students completed a questionnaire derived from the Self-Assessment Teamwork Tool for Students (SATTS) (Gordon et al., 2016) and Virtual Patient Evaluation (VPE) (Huwendiek et al., 2015) to assess teamwork and perceptions of authenticity, Evaluation (VPE) (Huwendiek et al., 2015) to assess teamwork and perceptions of authenticity, Evaluation (VPE) (Huwendiek et al., 2015) to assess teamwork and perceptions of authenticity, respectively. The mean INT score was greater than the mean VID score for two questionnaire items (p < 0.05). Students felt that in the INT simulation, teamwork was useful when problem-solving and the virtual simulation was authentic with regards to making decisions a nurse would make in real life.

Simulation has traditionally been conducted in-person through the use of manikins, however, the COVID-19 pandemic has challenged the practice of manikin simulation. Social distance constraints were enforced during the pandemic to reduce the potential spread of the virus and as a result, many educators and students were denied physical access to their universities' simulation facilities. Healthcare educators sought remote alternatives to manikin simulation and many resorted to instructional videos to educate their learners. While the use of videos increases safety, passively watching videos lacks interactivity which is an important component of simulation learning. In response to these challenges, we developed an interactive video simulation software that uses educators' existing video content to conduct a simulation remotely, thereby promoting safety during the pandemic while also meeting the interactivity standards of best practice for healthcare simulation. In this paper, we compare the interactive video simulation to the current practice of watching non-interactive video of a simulation using the same content. We found that interactivity promotes higher order learning, increases teamwork and enhances the perception of authenticity. Additionally, the majority of participants demonstrated positive reception of the interactive simulation.

We developed a new type of patient simulator called the Physical-Virtual Patients (PVP) which combines the physicality of manikins with the richness of dynamic visuals. The PVP uses spatial Augmented Reality to rear project dynamic imagery (e.g., facial expressions, ptosis, pupil reactions) on a semi-transparent physical shell. The shell occupies space and matches the dimensions of a human head. Methods. We compared two groups of third semester nursing students (N=59) from a baccalaureate program using a between-participant design, one group interacting with a traditional high-fidelity manikin versus a more realistic PVP head. The learners had to perform a neurological assessment. We measured authenticity, urgency, and learning. Results. Learners had a more realistic encounter with the PVP patient (p=0.046), they were more engaged with the PVP condition compared to the manikin in terms of authenticity of encounter and cognitive strategies. The PVP provoked a higher sense of urgency (p=0.002). There was increased learning for the PVP group compared to the manikin group on the pre and post-simulation scores (p=0.027). Conclusion.

The PVPS combines the tangible characteristics of a human-shaped physical form with the flexibility and richness of a virtual patient. The PVPS can exhibit a range of multisensory cues, including visual cues (eg, capillary refill, facial expressions, appearance changes), auditory cues (eg, verbal responses, heart sounds), and tactile cues (eg, localized temperature, pulse). Methods: We describe the implementation of the technology, technical testing with healthcare experts, and an institutional review board–approved pilot experiment involving 22 nurse practitioner students interacting with a simulated child in 2 scenarios: sepsis and child abuse. The nurse practitioners were asked qualitative questions about ease of use and the cues they noticed. Results: Participants found it easy to interact with the PVPS and had mixed but encouraging responses regarding realism. In the sepsis scenario, participants reported the following cues leading to their diagnoses: temperature, voice, mottled skin, attitude and facial expressions, breathing and cough, vitals and oxygen saturation, and appearance of the mouth and tongue. For the child abuse scenario, they reported the skin appearance on the arms and abdomen, perceived attitude, facial expressions, and inconsistent stories. Conclusions: We are encouraged by the initial results and user feedback regarding the perceived realism of visual (eg, mottling), audio (eg, breathing sounds), and tactile (eg, temperature) cues displayed by the PVPS, and ease of interaction with the simulator.(Sim Healthcare 15:115–121, 2020)}, keywords = {2020, Desiree Diaz, development, evaluation, Gregory F Welch, Jason Hochreiter, Juan Cendan, Laura Gonzalez, Mindi Anderson, pediatric patient simulation, physical-virtual patient simulator, pilot study, pvp, Ryan Schubert, Salam Daher, sepsis}, pubstate = {published}, tppubtype = {article} } @conference{richards2019analysis, title = {Analysis of Peripheral Vision and Vibrotactile Feedback During Proximal Search Tasks with Dynamic Virtual Entities in Augmented Reality}, author = {Kendra Richards and Nikhil Mahalanobis and Kangsoo Kim and Ryan Schubert and Myungho Lee and Salam Daher and Nahal Norouzi and Jason Hochreiter and Gerd Bruder and Gregory Welch}, url = {https://dl.acm.org/doi/10.1145/3357251.3357585}, doi = {10.1145/3357251.3357585}, isbn = {978-1-4503-6975-6/19/10}, year = {2019}, date = {2019-10-19}, urldate = {2019-10-19}, booktitle = {ACM Symposium on Spatial User Interaction (SUI)}, number = {3}, pages = {1-9}, abstract = {A primary goal of augmented reality (AR) is to seamlessly embed virtual content into a real environment.

However, some interactions, particularly those between a patient and healthcare provider, inherently include tactile components. We introduce an Intelligent Physical-Virtual Agent (IPVA) head that occupies an appropriate physical volume; can be touched; and via human-in-the-loop control can change appearance, listen, speak, and react physiologically in response to human behavior. Compared to a traditional IVA, it provides a physical affordance, allowing for more realistic and compelling human-agent interactions. In a user study focusing on the neurological assessment of a simulated patient showing stroke symptoms, we compared the IPVA head with a high-fidelity touch-aware mannequin that has a static appearance. Various measures of the human subjects indicated greater attention, affinity for, and presence with the IPVA patient, all factors that can improve healthcare training.}, keywords = {2018, Gerd Bruder, Gregory F Welch, Jason Hochreiter, Laura Gonzalez, Nahal Norouzi, neurological assessment, patient simulator, physical-virtual agents, pvp, Salam Daher}, pubstate = {published}, tppubtype = {conference} } @conference{daher2018physical2, title = {Physical-Virtual Agents for Healthcare Simulation}, author = {Salam Daher}, url = {PDF available upon request.}, year = {2018}, date = {2018-11-01}, booktitle = {ACM Intelligent Virtual Agent}, address = {Sydney, Australia}, keywords = {2018, physical-virtual agents, Salam Daher}, pubstate = {published}, tppubtype = {conference} } @conference{daher2018systematic, title = {A Systematic Survey of 15 Years of User Studies Published in the Intelligent Virtual Agents Conference}, author = {Salam Daher}, url = {PDF available upon request.}, year = {2018}, date = {2018-11-01}, booktitle = {ACM Intelligent Virtual Agent}, address = {Sydney, Australia}, keywords = {2018, Intelligent Virtual Agent, Salam Daher}, pubstate = {published}, tppubtype = {conference} } @conference{hochreiter2018cognitive, title = {Cognitive and Touch Performance Effects of Mismatched 3D Physical and Visual Perceptions}, author = {Jason Hochreiter and Salam Daher and Gerd Bruder and Gregory Welch}, url = {https://ieeexplore.ieee.org/document/8446574}, doi = {10.1109/VR.2018.8446574}, isbn = {978-1-5386-3365-6}, year = {2018}, date = {2018-03-18}, urldate = {2018-03-18}, booktitle = {IEEE Virtual Reality}, pages = {1-386}, address = {Germany}, abstract = {While research in the field of augmented reality (AR) has produced many innovative human-computer interaction techniques, some may produce physical and visual perceptions with unforeseen negative impacts on user performance. In a controlled human-subject study we investigated the effects of mismatched physical and visual perception on cognitive load and performance in an AR touching task by varying the physical fidelity (matching vs. non-matching physical shape) and visual mechanism (projector-based vs. HMD-based AR) of the representation. Participants touched visual targets on four corresponding physical-visual representations of a human head. We evaluated their performance in terms of touch accuracy, response time, and a cognitive load task requiring target size estimations during a concurrent (secondary) counting task. After each condition, participants completed questionnaires concerning mental, physical, and temporal demands; stress; frustration; and usability. Results indicated higher performance, lower cognitive load, and increased usability when participants touched a matching physical head-shaped surface and when visuals were provided by a projector from underneath.}, keywords = {2018, Gerd Bruder, Gregory F Welch, Jason Hochreiter, pvp, Salam Daher}, pubstate = {published}, tppubtype = {conference} } @misc{daher2017physical, title = {Physical-Virtual Patient Head}, author = {Salam Daher and Laura Gonzalez and Gregory Welch}, url = {PDF available upon request.}, year = {2017}, date = {2017-09-01}, urldate = {2017-09-01}, journal = {Florida Nurses Association}, keywords = {2017, Gregory F Welch, Laura Gonzalez, Salam Daher}, pubstate = {published}, tppubtype = {misc} } @conference{daher2017effects, title = {Effects of Social Priming on Social Presence with Intelligent Virtual Agents}, author = {Salam Daher and Kangsoo Kim and Myungho Lee and Ryan Schubert and Gerd Bruder and Jeremy Bailenson and Gregory Welch}, url = {https://link.springer.com/chapter/10.1007/978-3-319-67401-8_10}, doi = {10.1007/978-3-319-67401-8_10}, year = {2017}, date = {2017-04-01}, urldate = {2017-04-01}, booktitle = {ACM Intelligent Virtual Agents}, pages = {87-100}, address = {Stockholm, Sweden}, abstract = {This paper explores whether witnessing an Intelligent Virtual Agent (IVA) in what appears to be a socially engaging discussion with a Confederate Virtual Agent (CVA) prior to a direct interaction, can prime a person to feel and behave more socially engaged with the IVA in a subsequent interaction. To explore this social priming phenomenon, we conducted an experiment in which participants in a control group had no priming while those in an experimental group were briefly exposed to an engaging social interaction between an IVA and a nearby CVA (i.e. a virtual actor). The participants primed by exposure to the brief CVA-IVA interaction reported being significantly more excited and alert, perceiving the IVA as more responsive, and showed significantly higher measures of Co-Presence, Attentional Allocation, and Message Understanding dimensions of social presence for the IVA, compared to those who were not primed.}, keywords = {Co-presence, Intelligent Virtual Agent, Social presence, Social Priming, Virtual Human}, pubstate = {published}, tppubtype = {conference} } @conference{daher2017optical3, title = {Optical see-through vs. spatial augmented reality simulators for medical applications}, author = {Salam Daher}, url = {PDF available upon request.}, year = {2017}, date = {2017-03-01}, booktitle = {IEEE VR 2017}, address = {Los Angeles, CA}, keywords = {2017, Salam Daher}, pubstate = {published}, tppubtype = {conference} } @conference{daher2017optical2, title = {Optical See-Through vs. Spatial Augmented Reality Simulators for Medical Applications}, author = {Salam Daher}, url = {PDF available upon request.}, year = {2017}, date = {2017-03-01}, urldate = {2017-03-01}, booktitle = {IEEE Virtual Reality}, address = {Los Angeles, CA}, keywords = {2017, pvp, Salam Daher}, pubstate = {published}, tppubtype = {conference} } @misc{daher2017optical1, title = {Optical See-Through vs. Spatial Augmented Reality Simulators for Medical Applications}, author = {Salam Daher}, url = {PDF available upon request.}, year = {2017}, date = {2017-03-01}, urldate = {2017-03-01}, howpublished = {IEEE Virtual Reality}, keywords = {2017, pvp, Salam Daher}, pubstate = {published}, tppubtype = {presentation} } @conference{daher2017can, title = {Can Social Presence be Contagious?
