Different tasks and activities are associated with different sitting postures. The aim of this study is to investigate the influence of anthropometric characteristics and expectations on postural comfort perception while using four office devices: a desktop computer, a laptop computer, a tablet and a smartphone. A statistical sample of healthy students was selected, and their anthropometric characteristics were measured. The postures assumed by the participants were gathered non-invasively using cameras. Angular detection was performed directly on snapshots using Kinovea® software. The angles of human joints were used for the virtualpostural analysis, using DELMIA® software. The evaluation of postural comfort for each of the devices was obtained in two ways: CaMAN® software developed by researchers from the Department of Industrial Engineering in Salerno (Italy) was used to calculate the objective comfort indexes, and a questionnaire was used to evaluate the subjective comfort indexes. The results of the analyses show a difference between subjective and objective postural comfort for all of the devices, and this difference is associated to the expectations.

Abstract
Different tasks and activities are associated with different sitting postures. The aim of this study is to investigate the influence of anthropometric characteristics and expectations on postural comfort perception while using four office devices: a desktop computer, a laptop computer, a tablet and a smartphone. A statistical sample of healthy students was selected, and their anthropometric characteristics were measured. The postures assumed by the participants were gathered non-invasively using cameras. Angular detection was performed directly on snapshots using Kinovea® software. The angles of human joints were used for the virtualpostural analysis, using DELMIA® software. The evaluation of postural comfort for each of the devices was obtained in two ways: CaMAN® software developed by researchers from the Department of Industrial Engineering in Salerno (Italy) was used to calculate the objective comfort indexes, and a questionnaire was used to evaluate the subjective comfort indexes. The results of the analyses show a difference between subjective and objective postural comfort for all of the devices, and this difference is associated to the expectations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
