Fatigue is an important issue of concern for pilots. A high level of fatigue may well result in accidents, which ultimately leads to the loss of lives and resources.
To solve this problem and prevent a possible accidents, a team of researchers from the Indian Institute of Technology Kharagpur in conjunction with the Defence Institute of Physiology and Allied Sciences, DRDO, New Delhi has developed a ‘Fatigue Monitoring System’ for pre-flight assessment of Indian Air Force pilots.
The research and development (R&D) for the project was done at at IIT Kharagpur.
The equipment is based upon two parameters- physiological measure and a psychological measure.
While, the physiological measure is electrooculogram (EOG), the psychological measure is the performance of the pilot in a psychomotor vigilance test. EOG is a record of the standing electrical potential between the cornea and the retina, and is an indicator of eye movements.
The team has also utilised the concept of a psychomotor vigilance test (PVT) to designa game both for a PC as well as an Android device.
“What we have done is, we want to monitor the sleep without touching the body,” Professor Routray said in a statement.
