Abstract

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

Claims

1. An electronic whiteboard system, comprising:

a touch panel;

a display device that displays information related to writing data by the touch panel; and

a control device that is connected to the display device and the touch panel and includes an external or built-in storage device storing the writing data, the control device including

a pass code setting processing unit that inputs and sets a storage pass code on created writing data through the touch panel,

a writing data storage processing unit that stores the writing data by the touch panel in the storage device in association with the storage pass code provided from the pass code setting processing unit,

a pass code input processing unit that inputs a restoration pass code which is the same as the storage pass code through the touch panel,

a writing data acquisition processing unit that acquires writing data corresponding to the restoration pass code provided from the pass code input processing unit from the storage device when the writing data is present in the storage device, and

a whiteboard rendering processing unit that renders the writing data acquired by the writing data acquisition processing unit on the display device.

2. The electronic whiteboard system according to claim 1,

wherein the writing data storage processing unit stores a hash value of the storage pass code as a file name used when the writing data is stored in the storage device, and when there is writing data of a file name matching with the hash value of the restoration pass code, the writing data acquisition processing unit acquires the writing data.

3. The electronic whiteboard system according to claim 1,

wherein the pass code setting processing unit sets a predetermined character string as a part of the storage pass code in advance.

4. The electronic whiteboard system according to claim 3,

wherein the predetermined character string is date information at the time of pass code setting.

5. The electronic whiteboard system according to claim 1,

wherein the control device further includes

a page insertion processing unit that adds a new page to the writing data,

a previous page movement processing unit that performs movement from a page of the writing data that is being displayed on the display device to a previous page, and

a subsequent page movement processing unit that performs movement from a page of the writing data that is being displayed on the display device to a subsequent page.

6. An electronic whiteboard device, comprising:

a touch panel;

a display unit that displays information related to writing data by the touch panel; and

a control device that includes an external or built-in storage device storing the writing data, the control device including

a pass code setting processing unit that inputs and sets a storage pass code on created writing data through the touch panel,

a writing data storage processing unit that stores the writing data by the touch panel in the storage device in association with the storage pass code provided from the pass code setting processing unit,

a pass code input processing unit that inputs a restoration pass code which is the same as the storage pass code through the touch panel,

a writing data acquisition processing unit that acquires writing data corresponding to the restoration pass code provided from the pass code input processing unit from the storage device when the writing data is present in the storage device, and

a whiteboard rendering processing unit that renders the writing data acquired by the writing data acquisition processing unit on the display device.

7. A method of controlling an electronic whiteboard system, the electronic whiteboard system including a touch panel, a display device that displays information related to writing data by the touch panel, and a control device that is connected to the display device and the touch panel and includes an external or built-in storage device storing the writing data, the method comprising:

inputting and setting a storage pass code on created writing data through the touch panel;

storing the writing data by the touch panel in the storage device in association with the storage pass code provided from the pass code setting processing unit;

inputting a restoration pass code which is the same as the storage pass code through the touch panel;

acquiring writing data corresponding to the restoration pass code provided from the pass code input processing unit from the storage device when the writing data is present in the storage device; and

rendering the writing data acquired by the writing data acquisition processing unit on the display device.
