Abstract
Today, universities are actively making their lectures accessible to the
public. This research will use timestamps and eye-tracking in order to measure the utilization of video content. A timestamp in this context refers to elapsed time since the start of the video, and it is linked to a viewer. By using this timestamp, it be able to clarify their previously vague ideas in a relatively clear manner. On the other hand, Eye tracking can visualize the potential movement of video viewers and clarify viewers' focus points. And we can feed back to lecture material. We will also construct a platform where this timestamp and eye-tracking can be utilized, and support wide-ranging utilization of video content.
