Abstract
The aim of this study is to evaluate the characteristics of various kinds of VDT operations by using an analysis of eye movements and examining the distribution of gaze fixation points. Eye movements were detected by the “corneal reflection technique” and analyzed in terms of (a) tracing eye movements, (b) forming a matrix of fixation frequency, (c) describing the fixation area, and (d) adjusting the fixation vector. Five VDT operators involved in the development of computer software were selected as the subjects, with an average age of 24.8 years. Eye movements of the subjects were intermittently recorded throughout an 8‐hr working day. It was confirmed that an analysis of eye movements can be a meaningful way to characterize certain ergonomic aspects of VDT operations.Keywords
