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. These results support the importance of interactivity in students’ simulation experiences, especially in remote or virtual simulations in which students’ involvement may be less active.},

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).

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. Clinical Impact: Reducing the variability of wound measurements may improve patient outcomes, reduce wound prevalence, and mitigate the associated morbidity, mortality, and costs of these occurrences.},

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)},

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)

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. These results support the importance of interactivity in students’ simulation experiences, especially in remote or virtual simulations in which students’ involvement may be less active.},

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)},

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.

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.
