    • 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.
    • 固视识别系统包括眼跟踪装置和设置成与眼跟踪装置电通信的固视识别装置。 固视识别设备包括具有存储器和处理器的控制器,控制器被配置为将从眼睛跟踪设备接收的每个注视位置数据元素识别为注视位置数据和眼跳注视位置数据中的一个,每个注视位置数据元素 对应于与相应时间处的视野相关联的视觉位置; 识别与所述固视注视位置数据相关联的至少一个注视区域; 调整与所述至少一个固定区域相关联的多个固视注视位置数据元素; 并且基于调整的注视位置数据元素的数量来生成密度优化的注视区域。
