“…Other studies have confirmed that the effect of elevated height and lack of safety handrails increases anxiety and subjective stress triggered by fear of falling, which has been demonstrated to affect the neuromuscular system in both healthy and unhealthy people [ 19 , 20 , 28 ]. Similar reactions were also noticed in a group of at-height workers [ 13 , 17 , 23 , 31 ]. Respondents often use more conservative strategies to maintain postural control in settings of increased hazard arising from, e.g., elevation change [ 21 , 33 ].…”

“…It has been identified that increasing the elevation of the surface on which the worker stands alters postural control [ 21 , 22 , 23 ]. While maintaining an upright stance, workers were observed to use a strategy of stiffening the body, characterized by reduced amplitude and increased frequency of posture adjustment as well as leaning backwards away from the direction of danger [ 14 , 24 ].…”

The purpose of the study was to analyze the effects of cognitive task and change of height on the postural stability and cardiovascular stress of at-height workers. The study included 32 healthy men aged 25‒47. Due to the type of work performed, two groups were identified: at‒height workers, HW (n = 16), and office workers (mainly work at desk with a computer) OW (n = 16). The objective measures of postural stability (posturography) and cardiovascular stress (heart rate monitor) were evaluated for both groups at two different platform heights (ground level and 1 m above the ground) with or without cognitive task (backward counting). The increased height and the cognitive task were found to significantly affect measures of postural stability and cardiovascular stress. It was observed that in inexperienced OW employees, higher platform height and performing a cognitive task meant that posture stability significantly decreased, while cardiovascular stress and difficulties in maintaining balance increased. In HW group postural stability is less affected by distress conditions than in OW group.

“…Previous research has shown that working at higher elevations created both physiological and psychological fatigue for construction workers (Hsu et al, 2008). Other research has shown that visual depth and fear of heights in construction workers results in reduced task performance and increased unsteady movements when using a VR simulation (Habibnezhad et al, 2020). This high-fidelity assessment, using VR to simulate a heights scenario to evaluate task performance, is relatively novel in the research literature.…”

Virtual reality (VR) is a potential assessment format for constructs dependent on certain perceptual characteristics (e.g., realistic environment and immersive experience). The purpose of this series of studies was to explore methods of evaluating reliability and validity evidence for virtual reality assessments (VRAs) when compared with traditional assessments. We intended to provide the basis of a framework on how to evaluate VR assessments given that there are important fundamental differences to VR assessments compared with traditional assessment formats. Two commercial off-the-shelf (COTS) games (i.e., Project M and Richie's Plank Experience)were used in Studies 1 and 2, while a game-based assessment (GBA; Balloon Pop, designed for assessment) was used in Study 3. Studies 1 and 2 provided limited evidence for the reliability and validity of the VRAs. However, no meaningful constructs were measured by the VRA in Study 3. Findings demonstrate limited evidence for these VRAs as viable assessment options through the validity and reliability methods utilized in the present studies, which in turn emphasize the importance of aligning the assessment purpose to the unique advantages of a VR environment.

The self-report method has demonstrated accurate measurement for certain constructs in various contexts (Chan, 2009

“…Gamification elements are incorporated to capture the user's attention and challenge them to complete objectives [49][50][51][52][53][54]. Other studies have explored the study of emotional factors in user in a virtual reality environment, measuring the impact on the sensations experienced by the worker [55][56][57][58]. In this general context of virtual reality developments, patterns are identified: studies focus on specific scenarios, with different levels of realism (from basic to more advanced levels), with limited sets of simulated accidents.…”

Factors for the Automation of the Creation of Virtual Reality Experiences to Raise Awareness of Occupational Hazards on Construction Sites

Two of the differential characteristics of the AECO sector (architecture, engineering, construction and operation) are barriers for the mass creation of training materials for its workers. On the one hand, the workplace is unique and changing over time; on the other, the aging trend of its workers and the unattractive nature of the industry for new generations of professionals. These two problems can be tackled by virtual reality technologies, which allow the agile creation of all kinds of scenarios, while their current technology may be attractive to young people and intuitive for everyone. This work shows the results of an investigation that seeks to provide automated tools based on virtual reality experiences to support learning in occupational risk prevention. This objective is part of the development of a culture for prevention, which allows the treatment of the human factor, with all its complexity and casuistry. The proposal includes the development of a process and tools that allow replicating the specific scenario where the work will be carried out, incorporating risks and probable incidents, systematically establishing cause-effect relationships, incorporating a narrative (storytelling) that provides emotional meaning to users and Lastly, the creation of a workflow that facilitates the agile development of these virtual reality experiences for each specific work.
