Publisher Summary This chapter discusses the visual-display terminal (VDT) workstation design. Proper design and use of furniture assume flexibility in work organization and management attitudes. Providing freedom for individual variations from the conventional norm requires considering that persons working with computers differ in their physiques and work preferences. The ergonomic design of VDT workstations, their adjustability, and proper use can determine, by many and subtle interactions, the person's well-being and the related work performance. The output of the human–computer system is driven by the human. The main interaction is through eyes, ears, hands, and feet. Therefore, the body posture is largely determined by visual targets and by input devices, and by the seat. Ill-designed and ill-arranged computer workstations lead to health complaints and attitude problems, while ergonomic conditions further well-being, both physically and psychologically. The phanton of the average person sitting upright with right angles at elbows, hips, and knees should be abolished and replaced by a design model that incorporates the actual range of body sizes and of working postures, and their large variations reflecting individual sitting and standing preferences. |
