Design guidelines for limiting and eliminating virtual reality-induced symptoms and effects at work: a comprehensive, factor-oriented review

et al. 2023

Virtual reality (VR) can induce side effects known as virtual reality-induced symptoms and effects (VRISE). To address this concern, we identify a literature-based listing of these factors thought to influence VRISE with a focus on office work use. Using those, we recommend guidelines for VRISE amelioration intended for virtual environment creators and users. We identify five VRISE risks, focusing on short-term symptoms with their short-term effects. Three overall factor categories are considered: individual, hardware, and software. Over 90 factors may influence VRISE frequency and severity. We identify guidelines for each factor to help reduce VR side effects. To better reflect our confidence in those guidelines, we graded each with a level of evidence rating. Common factors occasionally influence different forms of VRISE. This can lead to confusion in the literature. General guidelines for using VR at work involve worker adaptation, such as limiting immersion times to between 20 and 30 min. These regimens involve taking regular breaks. Extra care is required for workers with special needs, neurodiversity, and gerontechnological concerns. In addition to following our guidelines, stakeholders should be aware that current head-mounted displays and virtual environments can continue to induce VRISE. While no single existing method fully alleviates VRISE, workers' health and safety must be monitored and safeguarded when VR is used at work.

“…However, the gain in speed came at the cost of accuracy as expected. Under visual control, participants achieved higher success rates for grabbing and dropping targets than operating outside their FOV without vision, which has been quantified in previous experiments [63,64,70]. Note that our targets were world-anchored and static; while the experimenter ensured that participants did not move from the position on the floor, shifts in upper-body pose may already result in a considerable effect.…”

“…Figure 8: HOOV's tracking accuracy over time (compared to OptiTrack tracking with sub-mm accuracy) in Study 1.Participants' interactions outside the FOV mostly occurred within the first three seconds, during which HOOV achieved the best tracking performance and which covers the majority of interactions outside the user's field of view[63]. HOOV's tracking also remains stable afterwards, where the median and mean position error does not significantly exceed 15 cm.…”

HOOV is a wireless sensing method that complements existing virtual and augmented reality headsets to support hand tracking outside the field of view of the headset's cameras. In this example app of our system, a participant is building a structure composed of blocks with different sizes. When the user places an object onto the structure, his hand is tracked by the headset's cameras (left). As the user reaches for a block just to his right (right), his hand leaves the field of view of the cameras. Now, HOOV continuously estimates the 6D position and orientation of the wrist using the 6-axis inertial measuring unit attached to the wrist during the time the hand stays outside the field of view.

“…But, Shen et al (2019a) report that tasks in a virtual environment versus a real office drive higher mental fatigue. Five studies experiment with various HCI aspects, which show that independent of the task goal, the interface and interactions already impact mental workload (Geiger et al 2018;Speicher et al 2018b;Zielasko et al 2019;Biener et al 2020;Gao et al 2021;Wu et al 2021). It appears that assistance within the interface helps to reduce mental workload and promote higher performance in VR (Geiger et al 2018;Gupta et al 2020;Gao et al 2021).…”

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

et al. 2022

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.
