ABSTRACT:
An electronic board system has a reduced display region at a lower portion of a writing screen on its electronic board, in addition to a non-reduced display region. A character, an image such as a graphic, etc., and an edit command, written on the reduced display region, can be entered into the electronic board system, and can be displayed on the non-reduced display region of the writing screen of the electronic board. Hence, the image displayed on the non-reduced display region can be seen by other persons in front of the electron board without interference from a shadow of the writer, and the electronic board can be manipulated with readiness and at high precision by a person who cannot reach an upper portion of its writing screen. Further, sensors capable of sensing the traces of the image are embedded in the rear of the writing screen so that the electronic board can readily be moved and can be prepared at reasonably low cost. The characters, images, edit commands, and so on written manually on the electronic board with a pointing device can be recognized and edited on the basis of the recognized command. The results of recognition are then projected onto and displayed on the writing screen of the electronic board.
