To provide a lecture system and a tabulation system enabling a lecturer to easily comprehend the reaction of a large number of participants to the lecture, and imposing less load on a network.

In the lecture system 100, feature data indicating each participant's gaze direction is transmitted to a management terminal 1 from a plurality of participant terminals 2, and the management terminal 1 performs statistical processing to the feature data to create statistical data and displays the display content on the basis of the statistical data on a display screen of a display section. Then, the lecturer using the management terminal 1 easily comprehends the reaction of the participants as a whole to the lecture by checking the display screen. Since the data transmitted from each participant terminal 2 is the feature data with small data amount, the load on a network is reduced, and the management terminal receiving the data easily carries out statistical processing.
