Abstract

The present invention relates to an electronic blackboard (board) which recognizes a user's touch input and displays writing even in color without requiring a separate pen tray for red, black, blue and other color writing implements (such as electronic pens) or an eraser. The invention enables the user to write on the electronic board in a selected color using either a writing instrument or a finger, and the invention informs the user which color has been touch-selected. Since there is no need for a pen tray, there is no possibility that a writing instrument can get lost. Using a conventional pen-tray introduces the possibility of selecting an undesirable electronic pen if the wrong colored pen has been misplaced in the tray. However, the present invention displays the color of the writing instrument through an LED and informs the setting of the selected color through vibration. Consequently, the invention is able to remarkably reduce the likelihood of using an undesirable electronic color pen.
