Background:
The ageing workforce is increasing in today's work environments, bringing unique challenges related to productivity and workload management especially in adapting into modern technology and high cognitive workload demands. The demands of modern work systems often worsen workload levels among ageing office workers, potentially affecting their performance and well-being.
Objectives:
This study explores the potential of Cognitive Ergonomic-Driven Technology (CEDT) as an intervention to mitigate workload and enhance work performance in ageing office workers.
Method:
The experiment involved the application of CEDT during task performance for both managerial and supporting staff. Performance metrics, Heart Rate measures, electroencephalogram (EEG) based Beta-Alpha Ratio (BAR)-measuring cognitive workload, and NASA Task Load Index (TLX)-measuring overall workload, all workload metrics were measured before and after the intervention. BAR is measuring the thirty participants involved in this study, evenly split between managerial and supporting staff.
Result:
The results demonstrate significant improvements in performance scores (PS) and reductions in strain indicators such as heart rate and BAR following the CEDT intervention. Correlation analysis revealed that effort demand (r = -0.542, p < 0.05) was a key factor influencing arithmetic task (task II) outcomes for managerial staff, while performance demand (r = -0.718, p < 0.01) was more critical for supporting staff in typing task (task I).
Conclusion:
These findings indicate that CEDT can enhance work performance and reduce workload among ageing workers, with varying impacts depending on the job role. Practical implementation may face challenges, including potential resistance to technology and cost implications, especially among ageing workers. Future research should explore long-term effects, particularly regarding cognitive fatigue and adaption over time, as well as the customization of CEDT for different job roles.
