[Problems to be Solved by the Invention] However, in a presentation application in which presentation contents are displayed on the screen and explained to the audience, the menu bar displayed on the screen is information unnecessary for the audience. For presenters, selecting a function from the menu bar during a presentation requires the tedious task of delicately operating the pointing device during the presentation, moving to a limited screen area, and clicking. In other words, there was a drawback that the user was distracted by the operation of the pointing device rather than the content of the announcement. Accordingly, an object of the present invention is to provide an interface that does not display a menu bar unnecessary for the audience on the screen and that is easy for the presenter to operate. [Means for Solving the Problems] The above object is achieved by a cursor moving means for inputting a position of a cursor displayed on a screen, and a virtual area obtained by dividing the screen into a plurality of areas based on an output of the cursor moving means. This is achieved by an area identification unit that determines whether the cursor is located in any one of the areas, and a screen processing unit that controls transition of display contents in screen units according to the virtual area based on the output of the area identification unit. You. [Operation] In other words, in the present invention, the virtual area is divided in advance into a plurality of virtual areas on the display, and the virtual areas are allocated so that different program processing is performed for each virtual area. Further, the area is limited from the X and Y addresses indicating the position where the pointing device exists, and when the click signal is supplied from the pointing device, different screen control corresponding to the virtual area unit is performed. I want to run. Therefore, the operator can switch the screen at a wide area level obtained by dividing one screen, that is, an independent virtual area different from the area normally displayed.

As will be described later, a to 22d are for displaying on the display 25 a specific cursor display type for performing different display depending on each area. Reference numeral 23 denotes an AND circuit which is opened only when an output signal from the cursor display control unit 22 and a click signal from the pointing device 20 are supplied. Reference numeral 24 denotes a processing unit.
a is activated, and the processing program (subroutine) corresponding to the program function assigned to each area is read from the file by the access of the controller 24a. The processing of the read processing program (subroutine) is executed in the execution unit 24c, and the result is displayed on the display 25. This file storage state will be described in detail with reference to FIG. 3. In the file 24b of FIG. 2, each processing is performed so that different processing is performed by designating the area corresponding to an area obtained by decomposing one screen. As shown in # 1 to # 4, subroutines 24b-1 to 24b-2 for displaying the next screen, the previous screen, turning on / off, and displaying the menu.
4b-4 are stored. Reference numeral 25 denotes a display for displaying the result of the above processing. According to the present invention, as shown in FIG. 5, one screen of the display 25 is divided into four regions by two virtual diagonal lines passing through the center point O from the four corners.
For the area 25a, the processing for switching to the next screen is performed.
Is a process for switching to the previous screen, a region C25c is for performing a lightening / darkening process on the entire screen, and a region D25d is for performing a menu display process. Each of the above processes is performed differently for each region when the cursor of the pointing device points to one of the regions and a click signal is supplied from the pointing device 20 when displaying something on the display 25. Is what you do. Further, in the present invention, the cursor of the pointing device 20 is
The display form of each area is different depending on the processing. That is, the sixth
As shown in the drawing, in the area A25a, although the cursor 26-1 is indicated by an arrow as in the related art, the tip of the arrow always points in the switching direction.
This is the same for the region B25b. On the other hand, in the area C25c, the display form of the cursor 26-3 is different, and has a shape indicated by oblique lines in the figure, and its internal area is filled in black. On the other hand, the display form of the cursor 26-1 is also different in the area D25d. In this area, for example, an initial letter “M” of a menu display is displayed in a form surrounded by a shape. The area C25c may be a shape having a white inner area, or an area D25c.
As for d, a tabular display may also be displayed. Each time the cursor of the pointing device 20 moves between the areas as indicated by the double-headed arrow in FIG. 6, the display form of the cursor changes cyclically in units of areas. The operation of the present invention will be described below with reference to the operation flowchart of FIG. [Step 40] First, for a system to which the present invention is applied, an operator performs a predetermined procedure to execute and start a presentation application. [Step 41] The system is read and a screen file is read. [Step 42] When predetermined preprocessing such as reading of a screen file is completed, an initial screen is displayed on the display 25. [Step 43] The operator operates the pointing device 20 such as a mouse. Then
The region identification unit 21 recognizes in which region the position where the cursor exists (points) is located. [Step 44] First, it is determined whether the cursor is located in the area A. This determination is determined by the X and Y addresses of the point indicated by the cursor. If it is located in the area A, the process proceeds to step 48. If not, the determination of the areas B to D is performed. The process proceeds to steps 45 to 47. At this time, the cursor display control unit 2
2, the display form of the cursor differs depending on the area where the cursor exists. [Step 48] If the cursor is located in the area A, the next screen icon is displayed. [Step 49] Check whether a click signal is supplied from the pointing device 20 such as a mouse (
For example, a click signal is issued when the left button of the mouse is pressed). If the button has been pressed, the process proceeds to step 50;
The processing up to 9 is repeatedly performed. [Step 50] When the click signal is supplied, the AND circuit 23 is opened, and the subroutine 24b-1 for displaying the next screen of # 1 is read from the file 24b in the processing unit 24 by the controller 24a. Hereinafter, the read subroutine 24b-1 for displaying the next screen is subjected to predetermined execution processing in the execution unit 24c, and the result is displayed on the display 25. [Step 45] First, it is determined whether the cursor is located in the area B. This determination is determined by the X and Y addresses of the point indicated by the cursor. If it is located in the area B, the process proceeds to step 51; otherwise, the determination of the areas C and D is performed. The process shifts to steps 46 and 47. At this time, the cursor display control unit 2
2, the display form of the cursor differs depending on the area where the cursor exists. [Step 51] If the cursor is located in the area B, a previous screen icon is displayed. [Step 52] Whether a click signal is supplied from the pointing device 20 such as a mouse (
For example, a click signal is issued when the left button of the mouse is pressed). If the button has been pressed, the process proceeds to step 53;
The processing up to 2 is repeated. [Step 53] When the click signal is supplied, the AND circuit 23 is opened, and in the processing section 24, the previous screen display subroutine # 2b-2 of # 2 is read from the file 24b by the controller 24a. Hereinafter, the read subroutine 24b-2 of the previous screen display is subjected to predetermined execution processing in the execution unit 24c, and the result is displayed on the display 25. [Step 46] First, it is determined whether the cursor exists in the area C. This determination is determined by the X and Y addresses of the point indicated by the cursor. If the cursor is located in the area C, the process proceeds to step 54. If not, the area D is determined. The processing shifts to. At this time, the cursor display control unit 22 changes the display form of the cursor depending on the area where the cursor is located. [Step 54] If the cursor is located in the area C, a screen lightening / darkening icon is displayed. [Step 55] Whether a click signal is supplied from the pointing device 20 such as a mouse (
For example, a click signal is issued when the left button of the mouse is pressed). If the button has been pressed, the process proceeds to step 56;
The processing up to 5 is repeatedly performed. [Step 56] When the click signal is supplied, the AND circuit 23 is opened, and the controller 24a reads the # 3 light / dark subroutine 24b-3 from the file 24b in the processing unit 24. The read / write dark subroutine 24b-3 is subjected to predetermined execution processing in the execution unit 24c, and the result is displayed on the display 25. In this example, the description will be continued on the assumption that the entire screen is darkened first, and then brightened. [Step 57] If the entire screen is to be lighted again after the display screen is darkened, a screen lightening icon is displayed. [Step 58] Check whether a click signal is supplied from the pointing device 20 such as a mouse (
For example, a click signal is issued when the left button of the mouse is pressed). If the button has been pressed, the process proceeds to step 59. If the button has not been pressed, feedback is provided to the previous stage of step 57, and the processes up to step 57 and step 58 are repeated. [Step 59] When the click signal is supplied, the AND circuit 23 is opened as before, and the controller 24a reads the # 3 light / dark subroutine 24b-3 of the file 24b in the processing unit 24 as described above. The read light / dark subroutine 24b-3 is subjected to predetermined execution processing in the execution unit 24c.
The result is displayed on the display 25, and the entire screen turns bright again. [Step 47] First, it is determined whether the cursor is located in the area D. This determination is determined by the X and Y addresses of the point indicated by the cursor, and if it is located in the area D, the process proceeds to step 54. At this time, the cursor display control unit 2
2, the display form of the cursor differs depending on the area where the cursor exists. [Step 60] If the cursor is located in the area D, a menu is displayed. [Step 61] Check whether a click signal is supplied from the pointing device 20 such as a mouse (
For example, a click signal is issued when the left button of the mouse is pressed). If the button has been pressed, the process proceeds to step 62. If the button has not been pressed, feedback is provided to the previous stage of step 43.
The processing up to 1 is repeatedly performed. [Step 62] When the click signal is supplied, the AND circuit 23 is opened, and the subroutine 24b-3 for menu display of # 4 is read from the file 24b in the processing unit 24 by the controller 24a. In the read menu display subroutine 24b-3, a predetermined execution process is performed in the execution unit 24c, and the result is displayed on the display 25. [Step 63] When a predetermined menu is displayed on the display, the operator selects an arbitrary menu, and the content corresponding to the selected menu is displayed on the display 25. As described above, among the different program processes for each area in the above-described embodiment, particularly regarding the light / dark display of the screen, the screen has been displayed with the light using the display, and the presentation and the like have been described. Then, when continuing the explanation using another blackboard, etc., the audience can pay attention to the blackboard by immediately turning the screen dark, so that it will not hinder the presentation process, The presentation can be continued smoothly. In the present embodiment, although the region for dividing the screen is described as being divided into four regions, other regions for performing a program process different from the above-mentioned four program processes may be separately set in the vicinity of the four corners. Especially for the four corners on the screen,
When the cursor of the device is moved, the region becomes the edge of the screen, so that the operator can easily operate the pointing device similarly to the above four regions, which is convenient. Furthermore, the pointing device of the present invention allows the cursor to be deformed into a pen shape by button operation, and using this pen, a character, a line drawing, and a drawing can be freely drawn in a selected color on the display screen as if by handwriting. It is possible to do. In addition, characters drawn by the pen-shaped cursor as described above are
The information in the two memories is displayed on the display in a superimposed form. The information in one of the memories can be erased by switching the screen in accordance with the program processing of the areas A and B. Therefore, by such switching, characters and the like drawn by the pen-shaped cursor can be erased. Throughout the present embodiment, the description has been made assuming that the mouse is used as the pointing device, but the same operation and effect can be obtained by using a touch panel or a light pen. [Effects of the Invention] As described above, according to the present invention, a presentation using a computer can be made without giving extra information to an audience, and a pointing device can be used by a presenter. When used, there is an effect that the presentation can be smoothly advanced without being distracted by complicated and delicate operations. Therefore, it greatly contributes to presentation using a computer.
