“…Besides these promising studies, several adverse effects of exposure to VR environments have been well-documented and may cause issues. Commonly cited are, for example, motion sickness [18], ocular system overload [19], decreased control of limbs and posture [45], decreased sense of presence [20], as well as the development of reactions inappropriate for the natural environment [46]. However, adverse effects such as motion sickness on the immediate user (e.g., patients) have been reduced to a minimum by advancing the technology development in recent years, leaving the adoption decision to the HC professionals (e.g., therapists) [47].…”

“…Although the potential of VR technologies in medical rehabilitation is well-known and researched, the clinical adoption of these technologies remains low [16,17]. Some of these practical hurdles can be attributed to the negative effects of VR technologies, including motion sickness [18], ocular system overload [19], and decreased sense of presence [20]. (Potential) users also express challenges in introducing VR technologies, such as privacy and security concerns and concerns regarding the patient population [7].…”

BACKGROUND The metaverse concept, gaining popularity since 2021, integrates technologies like virtual reality (VR) presenting novel opportunities for healthcare (HC). The use of VR technologies in HC, particularly in medical rehabilitation, has demonstrated effectiveness by enabling patient remobilization in virtual environments, offering real-time performance feedback, enhancing physical function and quality of life, and allowing patients to perform exercises autonomously. Nevertheless, integration of VR into routine rehabilitative practice is facing slow adoption due to concerns from HC professionals regarding data security and ethical considerations. OBJECTIVE This study seeks to explore how previous experience with VR technologies influences HC professionals' decisions to adopt or reject these technologies in medical rehabilitation. METHODS Using Rogers' diffusion of innovation theory, we conducted 23 semi-structured interviews with HC professionals from different rehabilitative fields in Germany. We grouped the interview participants regarding their innovativeness into VR experienced "innovators" and non-experienced "laggards". We apply qualitative content analysis techniques and categorize 26 adoption and rejection factors. RESULTS The identified 26 factors influence VR technology adoption and rejection. VR-experienced "innovators" showed different adoption patterns compared to non-experienced "laggards”, while factors of adoption hardly differed. CONCLUSIONS Addressing unique needs of both groups is crucial for wider VR acceptance in HC. The study enhances understanding of technology adoption, offering insights for developing strategies to improve VR integration in medical rehabilitation.

“…Based on these effects, several studies [48], [56], [57], [58] have created ocular biomechanical models to assess visual fatigue. In recent years, these biomechanical models are of particular interest to assess visual fatigue in unnatural environments like Virtual Reality (VR) or 3D animation environments [59], [60], [61], [62].…”

The purpose of this study is to explore the measurement of human factors in the workplace that can provide critical insights into workers' well-being. Human factors refer to physical, cognitive, and psychological states that can impact the efficiency, effectiveness, and mental health of workers. The article identifies six human factors that are particularly crucial in today's workplaces: physical fatigue, attention, mental workload, stress, trust, and emotional state. Each of these factors alters the human physiological response in a unique way, affecting the human brain, cardiovascular, electrodermal, muscular, respiratory, and ocular reactions. This paper provides an overview of these human factors and their specific influence on psycho-physiological responses, along with suitable technologies to measure them in working environments and the currently available commercial solutions to do so. By understanding the importance of these human factors, employers can make informed decisions to create a better work environment that leads to improved worker well-being and productivity.INDEX TERMS Human factors, industry 5.0, psycho-physiological signals, human physical and cognitive states, signal acquisition, measuring techniques, human-in-the-loop, industrial applications.

“…However, the impact is comparable with VR and 2D screen working tasks (text error corrections) for pupil size. Specific cumulative effect of immersion on eye movement (extraocular muscle excitation) has been observed while calculating a visual fatigue index through ocular biomechanics by Iskander and Hossny (2021) Apart from the population that is "stereo-blind," have missing or have non-measurable binocular depth perception, the proportion of concerned individuals varies according to the tested populations and measurement conditions from 2.2% to 32% (Lambooij et al 2009;Bosten et al 2015;Hess et al 2015). Moreover, although not necessarily impacting the discriminating abilities to determine an object's depth, the precision abilities of stereopsis diminish with age (Schubert et al 2016).…”

A narrative review of immersive virtual reality’s ergonomics and risks at the workplace: cybersickness, visual fatigue, muscular fatigue, acute stress, and mental overload

This narrative review synthesizes and introduces 386 previous works about virtual reality-induced symptoms and effects by focusing on cybersickness, visual fatigue, muscle fatigue, acute stress, and mental overload. Usually, these VRISE are treated independently in the literature, although virtual reality is increasingly considered an option to replace PCs at the workplace, which encourages us to consider them all at once. We emphasize the context of office-like tasks in VR, gathering 57 articles meeting our inclusion/exclusion criteria. Cybersickness symptoms, influenced by fifty factors, could prevent workers from using VR. It is studied but requires more research to reach a theoretical consensus. VR can lead to more visual fatigue than other screen uses, influenced by fifteen factors, mainly due to vergence-accommodation conflicts. This side effect requires more testing and clarification on how it differs from cybersickness. VR can provoke muscle fatigue and musculoskeletal discomfort, influenced by fifteen factors, depending on tasks and interactions. VR could lead to acute stress due to technostress, task difficulty, time pressure, and public speaking. VR also potentially leads to mental overload, mainly due to task load, time pressure, and intrinsically due interaction and interface of the virtual environment. We propose a research agenda to tackle VR ergonomics and risks issues at the workplace.
