In one example, the number of data input to the learning list for self-learning may mean a learning amount planned by a learner corresponding to the terminal device 102 . The server access period of the terminal device of the control device 101 may mean a time during which the terminal device 102 participates in self-learning in the second mode for self-learning. In one example, the number of times the self-learning participation request is received may mean the number of times the terminal device 102 receives data requesting participation in the self-learning from the control device 101 . The control device 101 may transmit data requesting participation in self-learning to the terminal device 102 based on the image data received through the terminal device 102 . For example, when the object for the learner is not recognized in the image data received through the terminal device 102 , the control device 101 may transmit data requesting participation in self-learning to the terminal device 120 . .
