Abstract: A visual tracking system, comprises an eye-tracking device and a cognitive load detection device disposed in electrical communication with the eye-tracking device, the cognitive load detection device comprising a controller having a memory and a processor. The controller is configured to receive eye-movement data from the eye-tracking device, the eye-movement data comprising pupil dilation event data and at least one of saccade event data and fixation event data, apply a classification function to the eye-movement data to detect a cognitive load associated with the eye-movement data and corresponding to a visual location of a field of view of the user, and output a notification regarding the cognitive load associated with the eye-movement data.

Abstract: A fixation identification system includes an eye-tracking device and a fixation identification device disposed in electrical communication with the eye-tracking device. The fixation identification device includes a controller having a memory and a processor, the controller being configured to identify each gaze position data element received from the eye-tracking device as one of fixation gaze position data and saccade gaze position data, each gaze position data element corresponding to a visual location associated with a field of view at a corresponding time; identify at least one fixation region associated with the fixation gaze position data; adjust a number of fixation gaze position data elements associated with the at least one fixation region; and generate a density optimized fixation region based upon the adjusted number of fixation gaze position data elements.
