On Monday, Indian Institute of Technology, Madras (IIT) stated that its researchers have confirmed that electroencephalogram (EEG) can be utilised to estimate brainwaves in workers, to assess mental sharpness, mainly through periods of crisis.
The measurements will aid in assessing the strength of the worker to react to a crisis and in turn, could limit accidents and misfortunes, they stated in a paper issued in the Journal of Computers and Computer Engineering.
The team of scientists has revealed the use of EEG, a method that measures brain activity, to estimate the workload human in a chemical plant control room.
The moderate level of mental energy that the cognitive workload that is absorbed by an individual to perform a task. High cognitive workload status of workers gives them likely to perform mistakes that can direct to accidents.
Rajagopalan Srinivasan, Department of Chemical Engineering, IIT Madras in a statement mentioned, “All our thoughts and activities are driven by electrical signals between the cells in our brain called brainwaves, which occur at different frequencies and are called alpha, beta, gamma, theta and delta.”
He further added, “The relative magnitudes of these waves along with their variation are a signature of our thought process and current mental state.”
As per IIT Madras, the team fit sensors to the heads of six people and had them do eight tasks individually.
The tasks were to monitor a common technical part for any interruptions which, if not managed, by the associate, in a provided period can lead to accidents.
Therefore, the essence of the work needed them to know the plant (industrial section) form and take proper choices and activities if any change happened.
The change raised the cognitive workload, and particularly if the exact resolution was done and the cognitive workload reduces.
The conclusions revealed that the number of ‘Theta Waves’ could recognise any mismatch within the worker’s mental representation of the method and the original plant performance while unusual circumstances.
The ‘theta band’ of brainwaves has been thought to be effective for the administration method of operating memory purposes, they said.
The purpose of the different cognitive workload, in aid, affects human performance, and certainly, the researchers discovered that the power phantom frequency in the theta band, compared favourably with members’ achievements and failures through the task.
This research was initiated by Prof. Rajagopalan Srinivasan, Department of Chemical Engineering, IIT Madras and the results of this research have been issued in the Journal of Computers and Computer Engineering in a paper co-authored by Prof. Rajagopalan Srinivasan, Mr Mohd Umair Iqbal, and Prof. Babji Srinivasan.
