Desenvolvimento e validação de um sistema automatizado para avaliação e classificação da postura durante atividade de teletrabalho em consonância com a ISO 11226

Abstract

We live in the moment of industry 4.0, in which the use of technology allows us to obtain real-time information about productive activities, allowing the manager to act quickly and dynamically in the face of the challenges imposed on him. Ergonomic risk management is part of managerial activities that have been gaining prominence due to its implications for workers' health, productivity gains and reduction of labor liabilities. For ergonomics to be inserted in the context of Industry 4.0, it is necessary to develop tools that enable automation in the collection and analysis of data related to work activities, in order to allow quick actions that face the dynamics and complexity of industrial activities. In 2020, as a result of the COVID-19 pandemic, there was a significant increase in teleworking, with the migration of 14 million workers in Brazil alone. Although the activities carried out in a telework environment contribute to social distancing and the control of the pandemic, there is still a gap in the means of evaluating the health of the worker, especially ergonomics, which allows the mapping of risks related to activities carried out in telework. The challenge includes developing an assessment method that at the same time guarantees the worker's privacy in relation to their home environment, but capable of collecting the data necessary to protect their health at work. Thus, the objective of this project was to develop an auxiliary ergonomics management system, based on ABNT ISO 11226 and other current ergonomic standards, which allows the collection and continuous analysis of biomechanical data, in real time, from teleworkers. The system was validated against experienced ergonomists and the agreement between them was calculated. The overall agreement for all 6 variables was 56%, from 15% (left knee flexion) to 83% (right elbow flexion and cervical flexion). Keywords: telework, ergonomics, COVID-19.
