Ad Eye Tracking Data set

Transformed Fixation Number (TFN): Ratio between gazing point number in AOI and duration of time in AOI. A higher ratio means the more gazing point in AOI.<br>Transformed Fixation Time (TFT): Ratio of Fixation Time between Duration Times in AOI. The higher of ratio, the longer of duration.<br>Average Gaze Duration (TFN): Ratio between TFN and TFT. This is a method that is popularly found among other eye tracking researches and is always chosen to evaluate the intensity of gazing point.转换注视点数量（Transformed Fixation Number, TFN）：指兴趣区（Area of Interest, AOI）内的注视点数量与该兴趣区内停留时长的比值，比值越高则代表该兴趣区内的注视点数量越多。 转换注视时长（Transformed Fixation Time, TFT）：指兴趣区内注视时长与该兴趣区内停留时长的比值，比值越高则代表该兴趣区内的停留时长越长。 平均注视时长（Average Gaze Duration, TFN）：指TFN与TFT的比值，该指标在当前眼动追踪研究中应用广泛，常被用于评估注视点的密集程度。
