Abstract

PURPOSE:To permit an operator to view guidance without moving a viewpoint except for the position of a cursor by displaying guidance near the cursor. CONSTITUTION:A cursor pointer corresponding to data stored in a coordinate register, namely coordinate data based on the position of a pointing device 39 is referred, and data stored in a cursor character pattern storage area is stored in the position concerned of a display memory 36. The stored data shows the cursor and guidance near the cursor on the display screen of CRT 38 by the control of a display control part 37. Thus, the operator does not need to change the viewpoint at the time of viewing the cursor and at the time of viewing guidance, and the work efficiency of the operator is improved when an interactive processing is frequent.

Description

[Detailed description of the invention] Industrial application field
The present invention relates to an information processing device that displays a cursor on a display device such as a T.

BACKGROUND OF THE INVENTION In recent years, information processing devices such as document creation devices and graphic creation devices have been equipped with C to improve the operability of interaction processing for the operator.
With the use of an RT display device, a bonding device such as a mouse has come to be used as an input device for positional information on a CRT.

The current position of the mouse is displayed as a cursor on the CRT, and the operator operates the mouse through the displayed cursor. Some of the cursor shapes that have been widely used in the past include fixed, simple figures such as the crosshair line shown at 11 in FIG. 4, with the center of the cross indicating the current position. This cross cursor moves on the display screen following the movement of the mouse.

However, when displaying a cursor with such a simple shape, the operator can only know the position information on the display screen from the cursor display during interaction processing between the information processing device and the operator, and the information processing It was not possible to know what action the device was requesting next. Therefore, the information processing apparatus displays guidance 12 as shown in FIG. 4 as auxiliary information for prompting the operator to perform the next operation using a part of the CRT screen.

Problems to be Solved by the Invention However, in this case, the combination of cursor display and guidance display requires the operator to change the viewpoint between looking at the cursor and guidance, which makes it difficult to process dialogue. If this occurs frequently, there is a disadvantage that the operator's work efficiency deteriorates.

In particular, as CRT display devices have become larger in recent years, there has been a tendency for the cursor position to be separated from the guidance display position, further reducing work efficiency.

Means for Solving the Problem In order to solve this problem, the present invention provides a control means for displaying guidance near a cursor displayed on a display screen of a display means based on coordinate data input from an input means. Be prepared.

Effect: With this configuration, guidance follows the movement of the cursor and is displayed near the cursor.

EXAMPLE Hereinafter, an example of the present invention will be described in detail with reference to the drawings. First, FIG. 1 is a block diagram showing the configuration of an information processing apparatus in an embodiment of the present invention.

Here, 31 is a processing circuit that performs logical judgments and calculations according to the flowchart shown in FIG. A main memory 32 has a program storage area PA in which a control program according to the flowchart shown in FIG. 2 is stored. A font memory 33 stores character patterns corresponding to character codes. 34 is a pointing device controller that counts the number of pulses accompanying the movement of the pointing device 39 and outputs coordinate data. A display memory 36 stores image data to be displayed on the CRT 38.

37 is a display control unit that causes the CRT 38 to display the data stored in the display memory 36. Reference numeral 40 denotes a readable and writable memory, which includes a coordinate register for storing coordinate data from the voting device controller, and a CRT 3 corresponding to the coordinate data stored in this coordinate register.
8, a cursor pointer for storing one data on the screen, a cursor image pattern and a character pattern storage area for guidance to be displayed in proximity to the cursor pattern, and a document for storing the document displayed on the CRT 38 as character code data. It has an area. 35 is a bus for exchanging data between the above devices.

The control procedure in the above configuration will be explained according to the flow chart shown in FIG. In step 1, the guidance data to be currently requested is retrieved from the memory. Then, in step 2, the character pattern of the characters constituting the guidance and the cursor pattern are written into the cursor character pattern storage area. In step 3, by referring to the data stored in the coordinate register, that is, the cursor position data corresponding to the coordinate data based on the position of the pointing device 39, the data stored in the cursor character pattern storage area is placed at the corresponding position in the display memory 36. Store. The stored data displays a cursor and guidance on the display screen of the CRT 38 under the control of the display control section 37. Next, in step 4, it is determined whether or not there is an instruction input from the pointing device 39, and if there is, the process moves to step 5, but if there is no instruction input, the process returns to step 3 and points to the pointing device 39.
The display position of the cursor and the guidance will be changed following the movement of 9. In step 5, the data of the cursor pointer or the data of the coordinate register when there is manual input from the pointing device 39 is fetched and processed.

A display example of this embodiment is shown in FIG. Here 13 is CRT
38 is shown on the display screen, 1 shows a cross-shaped cursor, and 12 shows guidance.

You are now in a state where you should input the starting point of the line segment, and "Enter the starting point" is displayed as guidance.

The data surrounded by the broken line on the screen is the data stored in the cursor character pattern storage area.

The data surrounded by the broken line moves on the screen as the pointing device 39 moves.

Effects of the Invention As described above, in the present invention, guidance is displayed near the cursor, so the operator can see the guidance without moving his/her viewpoint other than the cursor position.
