Introduction

The wishful thinking of the traditional VDT guides that average person sits upright with right angles at elbows, hips and knees is in dispute. Many studies have shown that the VDT users preferred to sit in a backward leaning posture with a longer viewing distance and a larger elbow angle and that the physical discomfort was reduced with preferred settings ( Grandjean et al., 1983; Ong, 1988).

Among factors that can possibly affect VDT workstation preferred settings, there are two factors deserving more attention, i.e. the different VDT workstation type and the preference difference in different ethnic groups. However, there is very little literature exploring these effects. Van der Heiden and Krueger ( 1984) reported a preferred forward monitor tilt setting (top of the screen toward the operator) at CAD workstations which was quite different from the preferred backward monitor tilt setting at PC workstations. As for the preference difference in different ethnic groups, though it can be concluded from previous studies that the preferred settings of VDT workstations are not greatly influenced by anthropometric factors ( Grandjean 1984). However, Ong ( 1988) still reported that the Singapore VDT users preferred a lower sitting and working height compared with European VDT users which was possibly due to differences in anthropometric dimensions.

Therefore, the present study was aimed to obtain the preferred settings of Taiwanese VDT users for both PC and CAD workstations, to see if there existed some differences between them and to compare them with previously reported data. Thus, these data will be useful for the manufacturers of computer workstation furniture and so be beneficial to VDT users.
