Abstract
Abstract Ocular surface area (OSA) is thought to be an informative index of visual ergonomics because OSA size is closely related to visual comfort. This paper presents a comfortable visual display terminal (VDT) workstation design based on an analysis of OSA. By measuring OSA while performing visual tasks with and without a VDT, it was clarified that the OSA was strongly affected by the composition of the VDT workstation, including placement of the display, keyboard, book and so on. It is recommended that the display be set at a lower position to realize a more comfortable workstation with a smaller OSA for the VDT operator.
