2A1-H08 Unobtrusive eye-tracker optical sensor to assess mental fatigue : Assess mental fatigue by using NASA TLX protocol

Abstract

This research reports the initial werk ofa novel nen-invasive method to evaluate a person's workload (fatigue). Ihis is done by using a non-invasiye optical sensor that will help te assess the subjective workload, Our system uti1izes dye sensitized selar cells (DSSC) as optical sensors. for 1ine-ofisight (LOS) and eye movement detector. Since the workload will be reflected in this ¢ yc movernent. we assess it under NASA Thsk-Load-lndex (TLX) protocol. a multidimensienal scale methodology:3 out of S sulijects were found to have good correlation between the workload and LOS.
