Description

[0001] Interactive board control system and method for smart lecture [0002]

The present invention relates to an interactive board control system and method, and more particularly, to an interactive board control system and method for smart lecture for controlling partner equipment using coordinate information.

In recent years, advanced systems have been established in classrooms and lecture rooms to enhance lecture efficiency. Typical examples include electronic lecture halls, electronic blackboards, and the like.

Such electronic teaching boards and electronic blackboards are usually executed based on a PC using a Windows OS or a remote server via a network. We use the term e-learning for online distance learning systems.

In addition, various lecture methods have been proposed in which an electronic lecture desk or an electronic blackboard is interlocked with a smart phone such as a student or a student, or an electronic lecture desk and an electronic blackboard interoperate to execute contents.

However, these electronic teaching boards and the electronic board have a disadvantage in that they are usually fixed in position or restricted in movement. That is, in order to use an electronic desk or an electronic board, a user must move to a place where the electronic desk or the electronic board is located, so that the contents can be controlled or written.

Therefore, it is necessary to study the interworking between the electronic desk considering the mobility and / or the electronic board and the smartphone.

On the other hand, an Android OS-based mobile board that is interlocked with an electronic lecture desk and / or an electronic blackboard has been proposed. This mobile board includes an interactive function that allows the contents to be executed to be executed in the same manner in the electronic desk and the electronic board. That is, it is possible to synchronize the content executed through the bidirectional communication between the mobile board and the electronic desk and the electronic board. In order to perform the interactive function, the compatibility problem between the Windows OS and the Android OS must be solved, and the interactive function is performed through mutual conversion.

However, although it is possible to synchronize the contents of the mobile board with the electronic lecture board and the electronic blackboard in real time, if the electronic board is written on the mobile board, or the electronic lecture board or the electronic board is written, There is a disadvantage that mutual synchronization is not performed. For example, if a professor moves to a mobile board while moving, the content of the book is not displayed at the corresponding position on the electronic board. Similarly, if the student writes to the electronic board, There is a drawback that does not.

In this way, it is necessary to study the interface solution for the user touch between the electronic board and / or the electronic board with the mobile board having different operating systems.
