Pulsavi meetod töötaja töö raskusastme ja energeetilise koormatuse määramiseks ja hindamiseks

Abstract

Human-centred evaluation of technology and work techniques requires the determination of the workload category and the internal workload, which is the internal response of the worker to exposure to external load factors in the work environment. The aim of this paper is to present a method for a human-centred analysis of the work process. The method requires the worker's physiological data, which is used to process their wirelessly transmitted heart rate. The processed heart rate is combined with a video feed and displayed in real time on a computer. This allows monitoring the worker's actions and the corresponding workload category, total energy expenditure, work-related energy expenditure, and base metabolic rate. Using the method does not interrupt the work process and it is possible to save the data for further analysis. The method has been recognised as an invention and is protected with patent EE 05807 B1.
