Service sector is a job that considered exposed to high mental demand. There lack of technique measure issues related the workload and fatigue levels among workers. Moreover, no studies have yet developed model predict especially for service It necessary investigate in real time working activities. The main purpose this study was identify trends relationship between level Ten participants with mean age 35.00±8.62 (SD) years took part study. Two experiments Without Rest (WoR) With (WR) segments involving data entry arithmetic tasks were conducted. Physiological measures using Electroencephalogram (EEG), Electrooculogram (EOG) heart rate (HR) assessed while performing tasks. result shows EEG alpha signal significantly higher at end WR compared WoR segment (p<0.05). Comparison each task show HR lower all This seven conceptual models strong variables correlations (r>0.05) evaluate variability both parts two types activities, namely, findings highlighted validated parameters methods are brain signals monitoring, performance measure.
