Electronic whiteboard system, electronic whiteboard device, and method of controlling electronic whiteboard

摘要

An electronic whiteboard system (1), including a touch panel (30); a display device (20) that displays information related to writing data by the touch panel (30); and a control device (10) that is connected to the display device (20) and the touch panel (30) and includes an external or built-in storage device (12) storing the writing data, the control device (10) including a pass code setting processing unit (62) that inputs and sets a storage pass code on created writing data through the touch panel (30), a writing data storage processing unit (61) that stores the writing data by the touch panel (330) in the storage device (12) in association with the storage pass code provided from the pass code setting processing unit (62), a pass code input processing unit (42) that inputs a restoration pass code which is the same as the storage pass code through the touch panel (30), a writing data acquisition processing unit (41) that acquires writing data corresponding to the restoration pass code provided from the pass code input processing unit (42) from the storage device (12) when the writing data is present in the storage device (12), and a whiteboard rendering processing unit (51) that renders the writing data acquired by the writing data acquisition processing unit (41) on the display device (20).
