“…Zimmerman (2017) defines task load as a measurement of human performance that broadly refers to the levels of difficulty individual encounters when executing a task. Multitasking can negatively impact task performance (Modi et al 2020). Stress and task difficulty impact cognition (Kim et al 2017).…”

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.

“…These novel devices can be held with the robot’s grasper, allowing the surgeon to directly control the suction tool from the console. Paradoxically, having the leading surgeon in charge of blood suction leads to additional cognitive demands (since there are other tasks that the surgeon is responsible for) that can result in delays and, potentially, medical errors 7 , 9 . These additional cognitive demands can be particularly detrimental for the less experienced surgeons as they diverge their attention from the main procedure 10 .…”

Adoption of robotic-assisted surgery has steadily increased as it improves the surgeon’s dexterity and visualization. Despite these advantages, the success of a robotic procedure is highly dependent on the availability of a proficient surgical assistant that can collaborate with the surgeon. With the introduction of novel medical devices, the surgeon has taken over some of the surgical assistant’s tasks to increase their independence. This, however, has also resulted in surgeons experiencing higher levels of cognitive demands that can lead to reduced performance. In this work, we proposed a neurotechnology-based semi-autonomous assistant to release the main surgeon of the additional cognitive demands of a critical support task: blood suction. To create a more synergistic collaboration between the surgeon and the robotic assistant, a real-time cognitive workload assessment system based on EEG signals and eye-tracking was introduced. A computational experiment demonstrates that cognitive workload can be effectively detected with an 80% accuracy. Then, we show how the surgical performance can be improved by using the neurotechnological autonomous assistant as a close feedback loop to prevent states of high cognitive demands. Our findings highlight the potential of utilizing real-time cognitive workload assessments to improve the collaboration between an autonomous algorithm and the surgeon.

“…In a recent study, Modi et al utilized a laboratory setting to examine the neurophysiological responses and consequences of surgical residents under different conditions. The authors noted that significant “performance degradation” occurs during high cognitive workload conditions, presumably because the simultaneous demand on both cognitive and motor tasks taxes the limited bandwidth of the prefrontal cortex 1 . We commend the authors for the application of optical neuroimaging to examine the consequences of distractions in the operating room setting.…”

“…We commend the authors for the application of optical neuroimaging to examine the consequences of distractions in the operating room setting. However, we disagree that “the neurophysiological basis for such significant performance decline has, until now, not been investigated.” 1 The costs of multi-tasking, or switching tasks, are well-known in the psychology literature.…”
