Abstract
The aim of the study was to analyze the post office user/customer interface, comparing two workstation layouts. The post office clerk was facing the client in one layout and seated at 45° with respect to the counter in the other. We analyzed the most frequent tasks presenting awkward postures: (1) payment of a postal order; (2) accepting a registered letter. These two tasks were further divided in their subtasks. We used an optoelectronic motion analysis system, and measured the Range of Motion (RoM) of trunk, arms and head. Using equipments placed on the employee left side the 45° workstation layout required less trunk and head torsion. A larger worktop improved the workstation, leaving more room for the equipments and allowing the worker to sit in front of screen and keyboard. However, this solution involved increased RoMs in the activities performed on both sides. The opto-electronic motion analysis system gave quantitative data still at the prototype stage. On the contrary, the most common standardized protocols, based on subjective observations, can give only qualitative evaluations. Furthermore, with the opto-electronic system, differently from simulation software that uses virtual settings, we are able to check the real interaction between the worker and the layout. From the quantitative data we can also extract useful information to help occupational doctors in managing healthcare protocols and to draw up a fuller, real assessment of biomechanical risks. Designers and planners could also use the data to study work layouts focusing at the same time to both on worker and on the process.
