Collection: ArticlesTitle: On the preferred viewing distances to screen and document at VDU workplaces / Wolfgang Jaschinski-KruzaAuthor: Jaschinski-Kruza, WolfgangNotes: Sumario: Previous research has shown that during work at visual display units (VDUs) most subjects prefer viewing distances greater than 50 cm. The present study investigates whether this is also true in those VDU tasks that require the subjects to shift their gaze frequently between the VDU screen and a paper document. In laboratory VDU task two conditions were compared: one in which both screen and document were located at the same viewing distance of 50 cm and another in which the distance to the document was 50 cm and the distance to the screen was 70 cm. It is suggested that VDU users may select viewing distances that they find comfortable in the range of more than about 50 cmRelated records: En: Ergonomics. - London and Washington. - Vol. 33, nº 8, August 1990 ; p. 1055-1063Materia / lugar / evento: ErgonomíaPantallas de visualización de datosCondiciones de trabajoPosiciones de trabajoDiseño del trabajoOftalmologíaSecondary titles: Título: Ergonomics Other categories: 875Rights: In Copyright (InC)
