The purpose of this study is to develop a fatigue evaluation system for a task with high precision work. A situation where human engaging high precision task, for example, in a work of endoscopic surgery and assembling small instruments is increasing in these days. It is thought that people working in precision work suffer not only with physical fatigue but also physiological stress. So, we tried to develop the evaluation system which includes physiological indicators and motion coordination simultaneously for analyses of precise work. In the system, physiological tremor and ESAM (Emotion Spectrum Analysis Method) using EEG (ElectroEncephaloGraph) signals were measured to analyze the situation that human was exposed in an imitative endoscopic surgery. The task was to retain a stylus to objective position in 3-dementional space. The results showed that ESAM indicated stress signal when the stylus moved unexpectedly.
