The aim of this study was to evaluate working conditions during VDT operation by analyzing of vertical eye movements and working postures at VDT workstations using flat panel display (FPD) and cathode ray tube (CRT). Fundamental experiments on eye movements and working postures were carried out to compare working conditions at VDT work in each workstation.
The average values for the vertical fixation points at the workstation using FPDs were lower than at those using CRTs. The average values of viewing distance at workstations using FPDs were shorter than those using CRTs. The postures with using tended to incline for frontal direction from the analysis of viewing and head angles. There was a high correlation in each pair, among viewing angle, neck angle and viewing distance.
It is obvious that FPD use is more appropriate than CRT use at VDT workstations, from the stand point of visual ergonomics considering vertical eye movement analysis as a factor in visual comfort. However, there are still many problems remaining unsolved in FPD use, which are screen reflection, changing in luminance contrast with different viewing angles and etc.
These problems probably influence not only visual functions but also working postures.
