Abstract
This paper describes step by step analytical procedures for adjusting two types of adjustable NBC workstations, namely, sit workstation and stand workstation, so that computer users can maintain an ergonomic work posture during prolonged computer use. Firstly, from the user’s gender and body height, and the NBC screen size, ideal settings of the NBC and workstation are computed. Next, depending on the NBC workstation type, an appropriate adjustment procedure is applied to obtain the final settings of the workstation. If necessary, the procedure recommends the use of certain workstation accessories. A validation experiment was conducted on four subjects using two adjustable sit and stand workstations. The results showed that the proposed procedures could recommend valid NBC and workstation settings. The postural analysis also confirmed that all subjects operated the NBC without awkward postures of the upper extremities.
