Abstract
In this paper, the authors show the results of an anecdotic experiment about the effect the use of eyeglasses has on the body posture of people in seated positions using different kinds of electronic devices: a desktop computer, a laptop, a tablet and a smartphone. The tasks were performed using a fully reconfigurable seating buck on which a standard VDT (Video Display Terminal) workplace with a chair was set. Subjects performed different tasks in order to evaluate the subjective perception of postural comfort. A Digital Human Modeling system was used to model and evaluate, from an ergonomic point of view, the ergonomic level. Software CaMAN®, was used to perform an objective evaluation of the postural comfort of subjects’ upper limbs and to compare the results obtained for the different subjects. The results show that the use of glasses has a significant effect on the body postures of the subjects.
