Method for communication among students based on online lecture smart device server and system for the same

摘要

The present invention relates to a communication method between students based on an online lecture and a smart device, a server, and a system therefor. According to the present invention, the server comprises: a sub-window providing means (320a-1) for generating, by a student, a sub-window UI screen output at a position different from that of a main output screen and distinguished from the main output screen for transmitting student data related to an online lecture to other users and controlling a transceiving unit (310) to transmit an online lecture application acceptance to at least two student smart devices (100) and a lecturer smart device (400); and a communication extraction module (320b) for designating a data transmission target using an identification ID or an identification image of each student displayed on the sub-window UI screen image, on the sub-window UI screen image provided for the student smart devices (100) and the lecturer smart device (400) by the sub-window providing means (320a-1), and then controlling the transceiving unit (310) to track a transmission path of a data transmission traffic when the student data related to the online lecture is transmitted. Therefore, a separate student communication space is provided in addition to a class through the online lecture provided on a main screen, thereby more smoothly sharing a lecture or data and further increasing participation in the lecture.
