Characteristics of visual display units that may cause visual difficulties.
The physical characteristics of a visual display unit (VDU) are compared to those of paperwork, through a review of the literature. Certain display characteristics are shown to enhance visual performance using a VDU whilst others significantly decrease it when compared to using hard copy. Overall, display characteristics do not necessarily render VDU use more difficult than if doing similar visual tasks without using a VDU.
