This paper discusses an experiment that was conducted to evaluate the effectiveness of a computer program, called ErgoNBC, which provides suggestions regarding the adjustment settings of notebook computer (NBC), workstation components, and selected accessories in order to help computer users assume an appropriate work posture during NBC work. Twenty-four university students voluntarily participated in the experiment which includes three experimental trials. In the first trial, the subjects were allowed to set up the NBC and workstation freely. In the second trial, the NBC and workstation were set up according to the recommendations from ErgoNBC. In the last trial, the subjects were given an opportunity to readjust the recommended settings. The Rapid Upper Limb Assessment (RULA) technique was used to evaluate their work postures during the three trials. The results of the paired t-test clearly showed that ErgoNBC could significantly help to improve the subjects' work postures.
