Representation of visual fatigue during VDT work using Bayesian network

Abstract

Technostress is the general term of the malfunction condition which treating the information management system accompanied by VDTs (Visual Display Terminals). The applied technology of ubiquitous computing will enhance the affinity between a computer and person. However, continuous use of VDTs sometimes causes technostress to us. The purpose of this study was to establish the method of reducing the visual fatigue during VDT work. In order to obtain a better reasoning result, it is necessary to deal with environmental information, VDT information and user information such as both psychological and physiological information, comprehensively. We, then, represent the causal association of visual fatigue using Bayesian network. Result showed the causal relationship between visual fatigue and VDT work factors visually.
