Abstract

PURPOSE:To designate attention information of a user himself by the leadership of the user, by making an attention source depending on a graphic display device virtual. CONSTITUTION:Attention information informed from a read attention source is changed as to its how to display and displayed as if an entirely different attention source exists. An attention information analyzing means 9 is provided newly in a T-GSP (a graphic subroutine package for TSS) 8. The attention information analyzing means 9 generates virtual attention information for executing an extraction of necessary information from attention information from a picture display device 2, or working of the attention, and delivers its virtual attention information to a user program 3.

Description

[Detailed Description of the Invention] [1 Already Required] Information input from a graphical display device is treated as attention information, but this attention information source is virtually increased to make a single attention source appear to be multiple. This is what I did.

[Industrial application field]

The present invention relates to a virtual attention source control method in which one attention source in a graphic display device is virtually increased to make it appear as if there are multiple attention sources.

[Conventional technology]

FIG. 4 is a diagram showing an outline of the display system.

In FIG. 4, ■ is a host computer, 2 is a graphic display device, 3 is a user program, 4 is a buffer, and 5 is a
is a tablet, 6 is a CRT, 7 is a keyboard, 8 is a T-
GSP (graphics subroutine package for TSS) is shown. The host computer 1 is
It has user program 3 and T-GSP8. T
- GS P 8 has (al) a function to convert graphic data prepared by the user program 3 into graphic data that can be interpreted by a graphic display device; A function to send figures to the device 2 and display them (C1 a function to perform operations on figure data or figures displayed on the display device, fdl) It has a function of notifying the user program 3 of attention, etc. A graphic display device 2 is connected to the tip of the T-GSP 8. The graphic display device 2 includes a buffer 4, a tablet 5, a CRT 6 and It has a keyboard 7.The buffer 4 holds graphic data for one screen displayed on the display device.The tablet 5 is for inputting graphics, and the keyboard 7 is for inputting characters. When a stylus pen (not shown) on the tablet 5 is pressed, an attention is generated.Similarly, when a function key (not shown) on the keyboard 7 is pressed, an attention is generated. .

Next, attention and attention sources will be explained. The attention is generated from a real attention source in the hardware of the graphics display device 2 and is notified to the user program 3 via the T-GSP 8. When the operator operating the graphic display device 2 wants to notify the user program 3 of the results of operating the attached devices of the graphic display device 2 (tablet 5, function keys on the keyboard 7, etc.), the operator raises attention to the user program. Specifically, to raise the user's attention, he/she may press the scrib pen on the tablet 5 or the ENTER key on the keyboard 7.

However, before that, it is necessary for the user to use the T-GSP 8 and perform a certain amount of registration work so that such a press action becomes an attention.

A source that generates attention is called an attention source.

Now, let's take Tablet 5 as an example. The functions of the tablet include a coordinate input function that notifies the user program 3 of the position indicated with the stylus pen, and a coordinate input function that informs the user program 3 of the position indicated with the stylus pen. There are two graphic input functions that notify you. In the case of this tablet, both of these two functions are notified to the user program 3 as an attention from the tablet 5, but the attention source that generates the attention is
There are two attention sources: one for coordinate input and one for graphic input.

Next, the contents notified to the user program by attention will be explained. What is communicated to the user program 3 by the attention from the graphical display device 2 depends on the type of attention source. - When the tablet 5 is the source of attention for inputting coordinates, the address of the location where the stylus pen is pressed is notified. However, some types of graphic display devices (for example, the F6242 graphic display device) have a tablet address in the coordinate system of the tablet 5 and the screens of the tablet 5 and the display device 2, as shown in FIG. When an action is taken, both the screen corresponding address will be notified. In Figure 5, if the X is pressed with the stylus pen, both the tablet address and the screen corresponding address will be sent to the user program as attention information. If the tablet address is notified and the X is pressed with the stylus pen, the tablet address will be notified, but the address corresponding to the screen will not be notified because it extends beyond the screen of the graphic display device.

[Problem to be solved] In the conventional technique, the method of notifying attention information from the attention source described above requires the user to specify one-to-one correspondence with the hardware attention source, and the notification information is also sent from the hardware. The information was communicated almost verbatim. In such cases, if there was any extra information, it would be deleted at the stage of notifying the user. For this reason, it was difficult to respond when a user requested information that had been decided to be deleted.

The present invention was created in view of this point, and it is an object of the present invention to provide a virtual attention source control method that allows one attention source to appear as a plurality of attention sources.

[Means for solving problems]

FIG. 1 is a diagram showing the principle of the present invention. In FIG. 1, numeral 9 indicates attention information analysis means.

The present invention changes the presentation of attention information notified from an actual attention source to make it appear as if a completely different attention source exists.

The attention information analysis means 9 is newly provided in the T-GSP 8. Attention information analysis means 9
creates virtual attention information by extracting necessary information from the attention information from the screen display device 2 or processing the attention information, and passes the virtual attention information to the user program 3.

〔Example〕

FIG. 2 is a diagram illustrating virtual attention to a tablet. Notification from hardware end flil&yo,
These are an attention identifier, a screen corresponding address, and a tablet address. The attention identifier from tablet 5 has the number "3", for example.

The notification information from the virtual attention source 1 to the user program is an attention source number (shown to the user as an external specification) and a screen-compatible address. The attention source number of the virtual attention source 1 is, for example, '33''.

If you want to read the attention from the attention source numbered “33”, user program 3 reads the attention source number “33”.
33'' to the attention information analysis means 9 to the effect that it wants to read the attention from the attention source.

Then, when an attention is received from the tablet 5, the attention number analysis means 9 notifies the user program 3 of the attention number and the address corresponding to the screen.

The notification information from the virtual attention source 2 to the user program is the attention source number, screen extension address, tablet address, and pen press location classification number. The attention source number of the virtual attention source 2 is, for example, “
63". If you want to read the attention from the attention source numbered "63", notify the attention information analysis means 9 that you want to read the attention from the attention source numbered "33". Then, the attention number When an attention is received from the tablet 5, the analysis means 9 notifies the user program 3 of the attention number, screen extension address, tablet address, and pen press location classification number.The screen extension address is the tablet address ( tablet coordinate system)
is translated in parallel so that the origin is at the lower left corner of the screen. What is the screen area on the tablet?
The attention information analysis means 9 is notified from the user program 3 in advance. Naturally, this information is also communicated to the graphical display device 2.

FIG. 3 is a diagram illustrating the processing of the attention information analysis module. What is the attention information analysis module?
This refers to the attention information analysis means 9.
