Influence of Expertise and Demographics on Perceived Ergonomic Risks in Physical Tasks
SessionPP3: Risk Perception
DescriptionThis study investigates how expertise and demographics affect perceptions of ergonomic risks and task convenience across three physically demanding task categories: assembly, culinary, and ladder-related work. Ninety-four participants—comprising professionals and laypersons—performed standardized tasks and rate each for perceived risk and convenience. Results showed that expertise significantly shaped ergonomic perceptions. Professionals reported higher convenience and lower risk in assembly and culinary tasks, particularly those involving repetitive tool use. Gender differences emerged in culinary tasks: female participants reported higher discomfort during slicing activities, suggesting that standard kitchen tools may not be ergonomically inclusive. In contrast, perceptions of ladder-related safety were more influenced by equipment features—such as sole grips and gloves—than by expertise or gender. These findings highlight the importance of inclusive ergonomic design and perception-aware interventions. The study advocates tailoring tools and training based on user experience and diversity to improve comfort, safety, and performance in varied occupational settings.
