Abstract In this paper, we propose a user-centered approach for the design of ergonomic workplaces. The method is based on the evaluation of subjective opinions and objective measures from the worker, while performing the industrial tasks. The ergonomic design of industrial workplaces will have impact in reducing the musculoskeletal disorders of workers.

1 Introduction Over the last decade, the improvement of worker ergonomics has become a relevant factor in industry, as it generates workers’ well-being, a decrease in absenteeism and, therefore, a cost reduction for employers [1]. The current methodology used in industry to design ergonomic workstations includes the following step: (i) initial design of the workstation according to international standards; (ii) ergonomic analysis of the worker inside the workstation; (iii) modification of the workstation in order to obtain a favourable ergonomic evaluation. Generally, the worker ergonomics is evaluated using empirical methods, as the RULA checklist [2], which considers kinematics and loading effects. This means that traditionally the ergonomic analysis of the workers is not directly included within the design process of workplaces, but it is performed

in a second step for verification and eventually modification of the workplace configuration. This practice might require several iterations to lead to convergence. Furthermore, the use of empirical methods as the RULA provides limited information, since only large angular variations of the human joints can cause a variation of the ergonomic index [3]. Another limitation is that these classic approaches do not provide information, or provide limited information, about the part of the body which presents greater overload or greater discomfort for the worker. To overcome these limits it would be preferable to include the ergonomics since the beginning, within the design process of industrial workplaces: this is in line with the recent trend of humanization of factories. This approach allows to design workspaces inspired by humans, maximizing the ergonomics while respecting the production standards (i.e. execution time of the tasks) [4]. To do that, objective measures calculated from biosignals o
