Cognitive load is the amount of mental resources required to execute a task. Psychophysiological researches show variations in electrodermal activity skin with cognitive load. State art studies mostly use exosomatic approach like Galvanic Skin Resistance (GSR) for measuring activity. However, recent advances made implementation wearable endosomatic devices motivated us bio-potentials measured using device assessing In present study, we have studied effect on human bio-potentials. We used 4-channel high-resolution during execution low and high versions addition tasks. Results suggest that there significant variation various levels which can be classify workload successfully. observed analyzed recorded from both hands feet. Combining potentials all 4 locations, classification accuracy obtained random forest classifier approximately 83.4% corresponding f-score 0.83. An optimum set features selected increases further 86.5%. Moreover, feature level fusion GSR signal gives an 89.4%. Thus, proposed provides immense scope based device.
