With increase in secondary tasks inside cockpit, cognitive load estimation became an important problem for both automotive drivers and pilots. The research problem is investigated in various names like drowsiness detection, distraction detection and so on. For automotive drivers, researchers explored various physiological parameters like heart rate, facial expression, ocular parameters and so on. In aviation there are numerous simulation studies on analysing pilots’ distraction and attention using various physiological parameters. For military fast jet pilots, researchers explored air to ground dive attacks and recorded cardiac, EEG and ocular parameters.
