Problems solved by technology
[0007] However, with the increase in the size of display devices such as liquid crystal displays, if a large display device is installed in a wide place such as a university classroom or an international conference room, it will be laborious to operate such as not being able to touch the upper part of the hand or writing to the end. Case
[0008] In view of this, none of the aforementioned JP-A No. 2000-56747 and JP-A No. 2002-196739 provides a unit for inputting the upper part or the end beyond the reach of the hand and a unit for inputting difficult positions.

Embodiment approach 1
[0029] In Embodiment 1, an information display device with a large display screen having an interactive whiteboard function will be described as an example. The information display device is a two-dimensional surface-type device that displays the computer desktop, and the interactive whiteboard function includes:
[0030] (1) Editable mode, which can input the user's writing of characters or drawings on its surface or editing operations of displayed objects (for example, displayed windows, characters, drawings, or images, etc.) into the computer,
[0031] (2) Non-editable mode for displaying originally displayed data as it is and inputting writing etc. on it into a computer, and
[0032] (3) A board off mode used as a display device of a computer.
[0033] Although the information display device can also be used as an electronic blackboard, it can be used as a more general conversational computer screen.
[0034] Examples of places where this interactive whiteboard function ...
Embodiment approach 2
[0116] In Embodiment 1 described above, a case has been described where the user performs input / editing on the same divided screen area after designating a sub screen. However, when it is desired to input / edit other divided regions, it is necessary to redo the input instructions one by one according to the sub-picture mode, so it is very troublesome.
[0117] In addition, there may be cases where it is desired to move the display position of the sub screen.
[0118] Therefore, in Embodiment 2, when the display screen is divided, the user can arbitrarily change to another divided area for input / editing, and further, the display position of the sub-screen can be moved.
[0119] Figure 9 It is a block diagram showing the functional configuration of the information display device according to the second embodiment. In this figure, the functions of the information display device include a control unit 31 , a sub-screen setting unit 32 , a position information conversion unit 33 ...

Abstract
An information display device having a large display screen that facilitates input / edit to a position away from the operation position of a user is provided. This information display device is equipped with a touch sensor on a display screen to enable an operation for screen display through a touch operation on the screen, equally divides the screen horizontally and vertically, sets a sub-screen area that displays a divided image of an image displayed on the screen, and transforms a touch operation position in the sub-screen area into a position on the display screen to replace a touch operation in the sub-screen area with an operation of the screen display on the display screen for enabling a remote operation.
Description
technical field [0001] The present invention relates to an information display device, in particular to a technique for displaying information using a large display screen capable of touch input. Background technique [0002] Existing whiteboards include a printing unit that optically scans the discussion content (image information) written on the whiteboard by a writing unit such as a magic pen, and prints the obtained image information on thermal paper. After the meeting is over, the agenda (image information) written on the whiteboard can be printed on thermal paper, and copies can be distributed to meeting participants. [0003] In addition, in conventional meetings using whiteboards, it is necessary to digitize printed agenda items by reusing a word processor or the like after the meeting ends. [0004] In Japanese Patent Laid-Open No. 2000-56747, an electronic conference system is proposed, which uses a direct input unit (for example, a stylus) to directly write the c...
