Design of Visual Display Terminal Paramaters for Visual Comfort and Performance

Abstract

The purpose of this study is to design the Visual Display Terminal parameters for the visual comfort and high performance. Taguchis Design of Experiments method was used to determine the optimum level of parameters that consist of external and internal lighthing, monitor position angle and eye-to-monitor distance. An experimental study was conducted in Ergonomics laboratory. Typing operation was done as a case study. 15 university student (7 males and 8 females) with age rangebetween 21-26 old took participation.The results of study findsthat the optimum external lighting (A1) = 1325 Lux, the monitor eye position angle (B2) = 15 o, The distance vision from eye - monitor (C1) = 20 inches, internal lighting (D1) = 60 Lux. This study has also found that eyesblinking decrease about 50% and the performance increase about 89.76%.Thus, the parameters of VDT can produce better visual comfort and performance.
