Posture and discomfort assessment in computer users while using touch screen device as compared with mouse-keyboard and touch pad-keyboard.
BACKGROUND: Touch screen computers require significant arm and hand movements. This can result to body discomfort and biomechanical load in users. OBJECTIVES: This study was carried out to examine posture and users' discomfort while using touch screen device as compared with mouse-keyboard and touch...

This can result to body discomfort and biomechanical load in users. OBJECTIVES: This study was carried out to examine posture and users' discomfort while using touch screen device as compared with mouse-keyboard and touch pad-keyboard. METHODS: Twenty three (23) students participated in this experimental study. The subjects completed pre-defined tasks in three 15 min trials by means of touch screen, touch pad-keyboard and mouse-keyboard as input devices. Postural angles were measured by Qualisys motion capture system. Body discomfort was assessed by a 10-cm visual analog scale. Rating scale was employed to assess the perception of subjects on the posture of body parts while utilizing the three devices. RESULTS: There was no significant difference in head inclination when using the three types of devices. Nevertheless, the mean of neck (<italic>p</italic> = 0.005) and trunk (<italic>p</italic> < 0.0001) inclinations as well as arm angle (<italic>p</italic> < 0.0001) while using touch screen, differed significantly from the two other devices and were more deviated from neutral posture. The type of input device was found to have significant effect on the right shoulder (<italic>p</italic> = 0.017), right elbow (<italic>p</italic> = 0.031), right wrist/hand (<italic>p</italic> = 0.004) and whole body discomfort (<italic>p</italic> = 0.026). Touch screen caused more discomfort in the mentioned regions when compared to the other two devices. Friedman test showed that differences of mean ratings for perceived shoulder and elbow postures in the 3 trials were significant (<italic>p</italic> = 0.005 and <italic>p</italic> = 0.011, respectively). Touch screen was the most unfavorable input device based on the subjects' judgment. CONCLUSION: Touch screen caused more deviated postural angles, increased body discomfort and unfavorable postures. pubtype: Academic Journal doctype: pictorial research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
