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.
