Abstract
User-preferred position of the computer display and the keyboard were quantified to determine how the size and/or the number of computer displays (19″, 24″, 27.5″, and dual 19″ LCDs) influence the positioning of the computer workstation components. Nineteen subjects performed a data entry task for 20 minutes with periodic repositioning of the display and the keyboard to their most comfortable setting. Subjects placed displays significantly (p<0.05) further as the size of display changed from 19″ to 27.5″ while maintaining the viewing angle to the top and center of display at or near eye height. Preferred position of the keyboard was not influenced by the display size. Results of this study indicate that the dimensions or adjustability of a computer workstation should be determined with consideration of the display size to accommodate both the keyboard and the display at their most preferred positions.
