title: Ergonomic intervention for improving work postures during notebook computer operation.
abstract: This paper discusses the application of analytical algorithms to determine necessary adjustments for operating notebook computers (NBCs) and workstations so that NBC users can assume correct work postures during NBC operation. Twenty-two NBC users (eleven males and eleven females) were asked to operate their NBCs according to their normal work practice. Photographs of their work postures were taken and analyzed using the Rapid Upper Limb Assessment (RULA) technique. The algorithms were then employed to determine recommended adjustments for their NBCs and workstations. After implementing the necessary adjustments, the NBC users were then re-seated at their workstations, and photographs of their work postures were re-taken, to perform the posture analysis. The results show that the NBC users' work postures are improved when their NBCs and workstations are adjusted according to the recommendations. The effectiveness of ergonomic intervention is verified both visually and objectively.
