Human Factors/Ergonomics (HFE) Evaluation in the Virtual Reality Environment: A Systematic Review

Abstract

A variety of human factors/ergonomics (HFE) problems have been studied by researchers and developers in VR environments. This systematic review aimed to summarize important HFE issues and classify the validated instruments used to quantify them in virtual reality environments. The most representative electronic databases for this review (2013-2022) were searched for original articles. The results showed that aspects, such as cybersickness, visual fatigue, mental workload, performance, spatial presence, and usability were the most relevant HFE issues assessed, whereas some aspects, such as physical workload, posture, stress, and discomfort, were consider less often. Previous studies have neglected some human factors and ergonomic issues, such as physical ergonomics, stress, and aftereffects, such as fatigue and human error. In virtual environments, presence was an emerging human factor compared to real environments. Most techniques were unidimensional and subjective. Future studies should focus on more factors and risks associated with HFE by emphasizing objective techniques and multidimensional subjective methods.
