Description

Electronic board and information transmission method

The present invention relates to an electronic blackboard, and more particularly, a display board having a position-coding pattern in which a plurality of dots are arranged on a plurality of grid lines spaced at regular intervals orthogonal to each other, and corresponding to a character or an image. The present invention relates to a copyboard and a copyboard information transmission method for reading a position-coding pattern by recognizing a dot with a digital pen and transmitting the pattern to an external module.

In general, a blackboard used in a conference room or a lecture room can write a content that is intended by a user, and if a mistake occurs during writing, the board performs a function and a role of erasing it with an eraser and writing again.

However, such a blackboard has a problem in that when chalk is used, a large amount of dust is generated, which adversely affects the human body, and the lecturer writes the contents written by the lecturer again in a personal notebook or simply memorizes them.
