System and method to dynamically assess and reduce user mental strain when operating information handling systems

1 . A computer-implementable method executed by an information handling system comprising a processor, memory, display, and one or more dye-sensitive photoelectric sensors integrated into the display, the method comprising:

capturing, by the dye-sensitive photoelectric sensors, light emitted from the display, reflected light from an eye of the user;

training the microservice of the information handling system with an initial data set that defines intensity of light based on captured reflected light;

converting intensity differences in the reflected light to time-series voltage values;

classifying, by the microservice, the time-series voltage values into opened-eye, blinked-eye, and closed-eye states based on voltage amplitude thresholds;

detecting spontaneous blinks and blink bursts by applying a first voltage change-rate threshold to detect an initial blink and a second voltage change-rate threshold lower than the first threshold to detect a subsequent blink within a burst;

calculating a fatigue index based on one or more parameters comprising number of blinks, blink burst rate, blink duration, and blink velocity over a defined monitoring interval; and

taking corrective action if the fatigue index meets or exceeds a fatigue threshold in regards to defined intensity of light, by transmitting an alert from the microservice to an operating system of the information handling system.
