Abstract

PURPOSE:To specify a designated area and to easily set a cursor at its desired position by changing the display area of the cursor which is displayed on a display device in response to a mouse device in accordance with the unit area where the cursor is positioned and at the same time moving the cursor at every display area. CONSTITUTION:A mouse 4 contains a control circuit 42 which arranges the information equivalent to the shift value of the mouse 4 as well as the state information on a switch 41 of the mouse 4 into a series of information forms. Then the circuit 42 receives a request A and sends a mouse information signal B to a mouse position information part 11. The part 11 calculates the speed and the absolute position of the mouse 4 to store them in a mouse position data part 13. A cursor display control part 12 calculates the address of a cursor on a cursor display device 2 based on the position information 13 and stores it into a cursor position data part 14. The area attribute information on each coordinates of the device 2 is stored in a picture area information part 15. The display position and the size of the cursor are decided by the value of the information 14 and the unit area information on the part 15. Then the cursor is moved by an amount equal to the number of areas corresponding to the shift pulses of the mouse 4 after the correspondence is secured between the number of said shift pulses and the number of areas where the cursor is moved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mouse device that is a pointing device, and particularly to a word processor.

The present invention relates to a method for displaying the designated area and amount of movement of a cursor on the display screen of a mouse device used in a personal computer or the like.

[Conventional technology]

Conventionally, pointing devices include a trackball device and a mouse device disclosed in Japanese Patent Laid-Open No. 51-83737. The amount of movement of the cursor on the display screen of the mouse device is designed to be fixed at, for example, 1:2 in consideration of operability.

Therefore, in order to achieve both the ease of specifying coordinates using a cursor and the ability to move the cursor at high speed,
No consideration was given.

In addition, with a cursor linked to a mouse device, it is easy to specify coordinates in dot units, but when specifying coordinates in units of characters, etc., it is difficult to use because it specifies unspecified coordinates of the specified area. was there.

[Problem that the invention seeks to solve]

In the above conventional technology, it is possible to accurately specify the cursor in a small area on the display screen, but
This has the disadvantage that the area in which the mouse device is moved becomes large. Further, in the case of a one-to-two design, the cursor moves quickly, but there is a problem in that it is difficult to set the cursor at an accurate position due to slight deviations caused by carelessness.

For these problems, for example,
As shown in No. 317, there are manual and automatic switching methods, but both have the disadvantage of complicated operations.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional drawbacks, an object of the present invention is to provide a method for displaying a cursor using a mouse device in which the target of the cursor displayed following the movement of the mouse device can be easily grasped and set. .

[Means for solving problems]

The above objective is achieved by changing the display area of the cursor displayed on the display device following the mouse device according to the unit area of the area where the cursor is located, and also by making the unit of movement of the cursor per display area unit. be done.

Generally, in a dot-based image area, the target of the cursor is a dot, and the number of movement pulse signals from the mouse corresponds to the number of dots that the cursor moves on the screen.In a character area, the target of the cursor is a dot. By using a character as a character and by associating the number of moving pulse signals from the mouse with the number of characters that the cursor moves on the screen, it is possible to easily set the position of the cursor and read the indicated area.

[Effect]

The attributes of the area where the cursor that follows the mouse device is located are detected by a main control device that comprehensively controls the mouse device, display device, and the like. By setting the cursor indication area according to the attributes of the detected cursor position and moving the cursor using the unit area of the area where the cursor exists, the indication area becomes clear and it is easy to set it to the target position. .

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a perspective view showing a general external configuration of a word processor using an embodiment of the present invention.

In Fig. 2, 1 is a main body, 2 is a display device, 3 is a keyboard, and 4 is a mouse device. A display device 2, which is a 0 display unit and which is a management device and also houses a flexible disk device 5 which is a recording medium, displays the status of created documents, menus, cursors, etc. Here, the cursor indicates the position where input is currently possible,
Used for specifying menu areas, etc. The position of the cursor is specified by pressing a scroll key on the keyboard device 3 or by moving the mouse device 4 on the console. A switch 41 is provided on the mouse device 4 and is used to set or delete a target area specified by the cursor.

FIG. 3 is a block diagram showing an overview of processing related to the mouse device in the overall configuration of the device shown in FIG. 2. The mouse data processing section 11 and the cursor display processing section 12 are internal to the control device within the main body 1. The mouse data processing unit 11 sends a data request signal A when requesting the mouse device 4 for its position information. The mouse device 4 has a control circuit 42 inside thereof, and arranges the position information of the movement of the mouse device and the on/off information of the switch 41 housed in the same device into a series of data format. Mouse device 4 sends data request signal A
When the mouse data signal B is received, the data arranged as described above is sent to the mouse data processing section 11 as a mouse data signal B in the form of a serial or parallel signal. The mouse data processing unit 11 calculates the speed and absolute position of the mouse based on the received mouse position information, and stores these data in the mouse position data unit 13. Here, the mouse position data obtained from the mouse device is displayed as a cursor on the display at a position equivalent to the mouse, and is used for menu selection and the like. The cursor display control section 12 calculates the address of the cursor to be displayed on the display from the mouse position obtained from the mouse position data section 13, and sends the result to the cursor position data section 14.
Store in. The screen area data section 15 stores area attribute information at each coordinate on the display. The position at which the cursor is displayed on the display and the size of the designated area are determined according to the value in the cursor position data section 14 and the unit area information in the area attribute information in the screen area data section 15. Note that the above processing is normally performed by a logical operation element such as a CPU.

FIG. 4 shows details of the timing of the mouse request signal A and mouse data signal B in FIG. 3. When mouse data signal B receives mouse request signal A, it sends out serial 3-byte data in synchronization with the rising edge of the pulse. The amount by which the mouse device was moved in the X direction during the time between the first byte or the request signal given last time and the request signal given this time is sent. The second byte, Y, is the same as X and is the amount of variation in the Y direction. The third byte SW gives the state of the switch 41 installed in the mouse between the previous request signal and the current request signal, with a value of 1 for an on state and 0 for an off state. In the timing diagram of FIG. 4, the mouse request signal A is normally given bipulses to the mouse device at regular intervals T.

FIG. 5 shows the absolute position of the mouse device when a mouse request signal A is given from the control device to the mouse device in the format shown in FIG. 4, and a mouse data signal B is sent from the mouse device in response. This shows the relationship between speed and speed. Since X and Y of the mouse data are the amount of movement of the mouse within a certain period of time, the absolute position of the mouse
, Ym are expressed as the sum of past X and Y, as shown in the table. Note that X and Y of the mouse data signal are shown as both positive and negative values depending on whether the direction of movement of the mouse device is positive or negative. Further, the speed of the mouse device is a value obtained by dividing the mouse data values X and Y during the mouse request signal period by the request period T. At this time, if T is a constant period, the values of the mouse data x and Y measured by the amount of movement themselves become values proportional to the speed.

As explained above, the absolute position and speed of the mouse are obtained, and by using these values, the cursor display control section 12 shown in FIG. 3 calculates the position of the cursor corresponding to the mouse.

In the conventional device, the relationship between the amount of movement of the mouse device and the amount of movement of the cursor display is proportional to the amount of movement of the mouse device and the amount of movement of the cursor display on the display. Therefore, if it is desired to make the mouse movement correspond to the cursor display in detail, by reducing the value of the proportionality coefficient, it becomes possible to move the mouse largely and reduce the movement of the cursor on the display. However, in this case, the smaller the value of the proportionality coefficient, the easier it becomes to set the position of the cursor, but a problem arises in that the mouse movement area for moving the cursor a certain distance becomes larger. In addition, in order to be able to set the most detailed area of the possible target areas, the cursor instruction area is specified in dot units, so for example, when specifying one character in a string, When the cursor is positioned in the middle of one character, it is difficult to tell which character is selected.

FIG. 6 is a flowchart explaining cursor control in the present invention. At the beginning of cursor processing, the amount of mouse movement is detected, and the cursor position is calculated in conjunction with the previous cursor position data. Calculated position data and screen area data section 1
5, the area attribute of the cursor position is determined, the amount of movement of the cursor and the size of the designated area are determined, and the cursor is displayed on the display. After waiting a certain period of time, the amount of mouse movement is detected again and the same process is repeated to continue moving the cursor.

FIG. 1 shows an example of cursor control by a mouse device according to the present invention.

The figure (a) shows a conventional example for comparison, and the figure (b) shows an example according to the present invention. In the conventional example, a general arrow-shaped cursor was used.

In these examples, the character area consists of an 8×8 dot area, and the graphic area is handled in units of 1 dot.

In (a), the unit of movement of the cursor is dots, regardless of whether it is in the character area or the graphic area, and to move the cursor position from ■ to ■, the mouse device must be moved 13 units, and when the position of ■ is When the cursor moves, it is difficult to tell whether the cursor is pointing to A or B.

On the other hand, in (b), the unit of movement of the cursor in the character area and the graphic area is each unit area, so in order to move the cursor placement from ■ to ■, you need to move the mouse device 3 units. good. In addition, in this example, in the character area, the area indicated by the cursor is shaded,
Since the cross line is used in the graphic area, even when the cursor moves to the position marked ■, it can be easily determined whether the cursor is pointing to A or B.

According to this embodiment, not only is it easy to understand and set the target of the cursor, but also the attribute of the area where the cursor is currently located can be understood by changing the size of the area pointed by the cursor.

〔Effect of the invention〕

As described above, according to the present invention, the ratio between the amount of movement of the mouse device and the amount of movement of the cursor on the display is fixed, and if the unit area of the area where the cursor is located is large, the cursor moves quickly and the cursor position If the unit area of the area to be moved is small, the cursor moves slowly and is weighted, which has the effect of not only making it easy to set the cursor position, but also making it easier to grasp the target of the cursor. There is.
