This research reports the initial work of a novel non-invasive method to evaluate a person's workload (fatigue). This is done by using a non-invasive optical sensor that will help to assess the subjective workload. Our system utilizes dye sensitized solar cells (DSSC) as optical sensors, for line-of-sight (LOS) and eye movement detector. Since the workload will be reflected in this eye movement, we assess it under NASA Task-Load-Index (TLX) protocol, a multidimensional scale methodology. 3 out of 5 subjects were found to have good correlation between the workload and LOS.
