“…Our goal this time was to observe a simple HMD. Previous research that used the HMD reported that their aims included establishing a remote education system of surgical methods [23] and a system using the Oculus Rift to create a simulation or medical VR environment [33]. These studies are considered useful in clinical practice and/or surgery settings.…”

“…Various head-mounted display (HMD) devices, such as Oculus (Facebook), VIVE (HTC), and Hololens (Microsoft), have been developed and are available in the market today. Moreover, wearable devices such as Google Glass (Google) and Hololens [10,20-23], the usefulness and feasibility of which are being studied, are used for medical purposes. 3D model presentation methods include both monitors and HMDs; nowadays, 3D printers are also employed [24,25].…”

Background Virtual reality (VR) technology has started to gain attention as a form of surgical support in medical settings. Likewise, the widespread use of smartphones has resulted in the development of various medical applications; for example, Google Cardboard, which can be used to build simple head-mounted displays (HMDs). However, because of the absence of observed and reported outcomes of the use of three-dimensional (3D) organ models in relevant environments, we have yet to determine the effects of or issues with the use of such VR technology. Objective The aim of this paper was to study the issues that arise while observing a 3D model of an organ that is created based on an actual surgical case through the use of a smartphone-based simple HMD. Upon completion, we evaluated and gathered feedback on the performance and usability of the simple observation environment we had created. Methods We downloaded our data to a smartphone (Galaxy S6; Samsung, Seoul, Korea) and created a simple HMD system using Google Cardboard (Google). A total of 17 medical students performed 2 experiments: an observation conducted by a single observer and another one carried out by multiple observers using a simple HMD. Afterward, they assessed the results by responding to a questionnaire survey. Results We received a largely favorable response in the evaluation of the dissection model, but also a low score because of visually induced motion sickness and eye fatigue. In an introspective report on simultaneous observations made by multiple observers, positive opinions indicated clear image quality and shared understanding, but displeasure caused by visually induced motion sickness, eye fatigue, and hardware problems was also expressed. Conclusions We established a simple system that enables multiple persons to observe a 3D model. Although the observation conducted by multiple observers was successful, problems likely arose because of poor smartphone performance. Therefore, smartphone performance improvement may be a key factor in establishing a low-cost and user-friendly 3D observation environment.

“…The performance of the HMD and built-in screen-based systems was reported in the experiments. Rojas-Munoz et al (2018) found that an AR HMD yielded smaller performance errors and fewer focus shifts in comparison with a telestrator system in which mentees used a nearby screen to retrieve the instructions. Andersen et al (2017) developed a tablet display system similar to an HMD in which a tablet was positioned between the operating field and the local surgeon's head.…”

“…In 19 (76%) of the experiments, a new AR prototype was developed, while the remaining (6 or 24%) used or modified AR devices developed by a third party. Microsoft HoloLens version 1 (Microsoft, 2019) was used in five experiments (Hanna et al, 2018;Lin et al, 2018;Mitsuno et al, 2019;Rojas-Munoz et al, 2018;Wang et al, 2017), and Google Glass (Google, n.d.) was used in one experiment (Ponce, Menendez et al, 2014).…”

This systematic review aimed to identify how tele-mentoring systems that incorporate augmented reality (AR) technology are being used in healthcare environments. A total of 12 electronic bibliographic databases were searched using the terms “augmented reality”, “tele-mentoring” and “health”. The PRISMA checklist was used as a guide for reporting. The mixed method appraisal tool was used to assess the quality of the included experiments. The data were then analysed using a concept-centric approach and categorised primarily with regards to system performance and task performance measures. A total of 11 randomised controlled trials and 14 non-randomised designs were included for review. Both mentees and mentors assessed the system and task performance according to 25 categories. The feedback of mentees using AR tele-mentoring systems was generally positive. The majority of experiments revealed that the AR system was an effective tele-mentoring device overall and resulted in the effective performance of a procedure. Benefits included improvements in trainees’ confidence, task completion time and reductions in task errors and shifts in focus. However, the systems had limitations, including heaviness of the equipment, inconvenience, discomfort and distraction of wearing devices, limited battery life, the latency of video and audio signals and limited field of view. Implications for practice or policy: Health practitioners can apply AR technology to receive and follow real-time annotated instructions verbally and visually from remote experts. Technical developers may consider improving AR devices in terms of lighter weight, larger field of view, more ergonomic design, more stable network connection and longer battery life. Further AR-related experiments may need to explore AR tele-mentoring systems’ utility across healthcare environments with larger samples, real patient populations in remote settings, cost-benefit analysis and impacts on short- and long-term patient outcomes.

The need for sound anatomical knowledge is woven into the daily tasks of all health-care professionals, whether directly (e.g., surgical landmarks) or indirectly (e.g., understanding the pathophysiology of a disease) (Singh et al., 2015). Anatomy educators are searching for new, effective, and innovative means to teach medical trainees and professionals, beginning with two-dimensional (2D) images, plastic models, human cadavers, and, more recently, with the use of augmented reality (AR; Singh et al., 2015). Modern approaches to health sciences education and practice are now evolving with the increasing accessibility, affordability, and advancement of virtual reality (VR) and AR technologies (Gallagher et al., 2005;Riva & Wiederhold, 2015). Technologies such as VR and AR allow the user to understand, explore and appreciate spatial relationships using sensory-driven pathways (Dalgarno et al., 2002;Huang et al., 2010;Wu et al., 2013;Küçük et al., 2016). Despite the frequent use of the term VR and AR, their applications vary across studies. It is therefore vital to not only define these terms, but also have a deeper understanding of the reality-virtuality (RV) continuum by Milgram and
