Investigating the Influence of Cognitive Demands and Personal Factors on Work-body Postures
Mental workload is a broad concept used by human factors and ergonomics professionals. It has become a topic of increasing importance since the introduction of technology in modern working environments. Mental workload assessment is an important component in the design of occupational tasks since inappropriate levels can cause errors and incidents, affect performance, and be responsible for occupational diseases and musculoskeletal disorders. Understanding how mental workload dynamically affects performance, modulates human-machine interaction, influences overall system output, and its role on workers’ health implications is increasingly crucial in designing efficient and safe systems and workplaces. Until now, all the research studies have explored the effects of physical activity on mental workload assessment. No study has analyzed the effects of mental workload on body postures even though studies have stated that in response to new information from the workplace environment, the human body orients in the direction of a stimulus, and this orientation reaction could affect the ongoing activity. This study is focused on the analysis of body postures as an easily observable and easily measured aspect that could reflect mental workload. The study's main hypothesis is that body posture can be used to describe mental workload in some contexts and therefore should be considered a supplementary method to advance the state-of-the-art in workload measurements. Other individual variables such as age, gender, personality type, and anxiety will be included in the study to evaluate if they mediate or exacerbate the influence of the work organizational factors.
