[Application of microcomputer to VDT's work].
The VDT is composed of CRT displays, which are like a television display & a keyboard combined & it plays an important role between man & computer, & we can also get the response & messages from a computer with the VTD. For evaluation of responses to VDT work, we close EEG as an index of stress, & also designed the visual search test. On the other hand, as a cross-reference experiment, we developed a paper work test to do in the same way as on the VDT. In order to grasp the characteristics of the EEG, a three-way analysis of variance was applied using two types of wave band data. Factor A means the effect of working time. Factor B indicates the effect parts on the head & Factor C presents the difference in age groups. And thus, this limited data provide evidence for the relationship between variations in EEG & performance.
