The present invention relates to a cursor control method for a device that moves a cursor using a mouse.

The menu selection function using a mouse has been adopted in many display devices as a means of improving operability.
There is a demand for faster and more accurate menu selection.

[Conventional technology]

FIG. 4 is a block diagram illustrating a conventional example, and FIG. 5 is a diagram illustrating the operation status of menu selection.

The block diagram shown in FIG. 4 is used to specify the coordinates on the CR7 display screen 8 when specifying characters or menus displayed on the CR7 display screen 8 with a cursor, or when drawing pictures etc. on the CRT display screen 8. An X-direction movement counter 2 that counts the amount of movement of the mouse 1 to be instructed and the movement of the mouse 1 in two-dimensional directions. A cursor moving unit 6 that determines the movement position of the cursor based on the output values from the Y direction movement amount counter 3, the X direction movement amount counter 2 and the Y direction movement amount counter 3, and displaying the output information from the cursor movement unit 6. A display memory 7 for storing information as information, and a CR7 display screen (CRT display) 8 capable of displaying different contents stored in the display memory 7 as visible images on a plurality of display areas. It is equipped with:

FIG. 5 shows a display menu on the CR7 display screen 8, and in this example, 16 menu items ① to [phase] can be displayed. Incidentally, the large rectangular area in FIG. 5 is the menu display area, and the small rectangular areas to which ■ to [phase] are added are menu items selected by the cursor.

For example, if you move the cursor by operating mouse 1,
When moving to the menu item ■ indicated by the arrow in the figure, as the mouse 1 moves, the amount of movement in the X and Y directions detected and output internally is calculated by the X direction movement amount counter 2 and the Y direction movement amount counter 3. Count with .

The counted values of the X-direction movement amount counter 2 and the Y-direction movement amount counter 3 are sent to the cursor moving unit 6 and determined as the movement amount of the cursor, and the values are set in the display memory 7.

As a result, the cursor is moved in conjunction with the movement of the mouse 1. This cursor can be freely moved to the entire menu area on the CR7 display screen 8, that is, within each menu item - [phase] and between each menu item - [phase].

[Problem that the invention seeks to solve]

As described above, when you operate the cursor in conjunction with the movement of mouse 1 and select one menu from multiple menus, the cursor moves in the same way as mouse 1, and you can freely move within each menu item I will have to move.

Therefore, for example, if the cursor is moved by a small movement of the mouse 1, it will move out of the specified menu item,
Since fine movements may be repeated multiple times to set the specified position, the menu selection operation may take a long time.

[Means for solving problems]

FIG. 1 shows a block diagram illustrating the invention in detail.

The principle block diagram of the present invention shown in FIG. 1 is based on the functional blocks 1 to 3 and 6 to 8 explained in FIG. It is configured to include a menu search means (menu search unit) 40 that searches for the menu closest to the current position, which is determined by the amount of movement.

[Effect]

The movement direction and movement amount are determined based on the values output from the X direction movement amount counter 2 and the Y direction movement amount counter 3, and the movement direction and movement amount are stored in the menu search means (menu search unit) 40. By searching for the closest menu based on the menu address information in the menu and moving the cursor directly into that menu, menu selection operations using the mouse can be performed easily and quickly. It becomes possible to process

〔Example〕

The gist of the present invention will be specifically explained below with reference to embodiments shown in FIGS. 1 to 3.

FIG. 2 is a block diagram explaining the present invention in detail, and FIG. 3 is a diagram explaining the menu search situation in the embodiment of the present invention. Note that the same reference numerals indicate the same objects throughout the figures.

The block diagram shown in FIG. 2 is a diagram showing an embodiment of the menu search section 40 shown in FIG. an arithmetic circuit 41 that calculates movement direction information A and movement amount information B; a search circuit 42 that searches for a range of movement direction information A using movement direction information and movement direction information A stored in advance in a memory 43; and a memory 43. 43, a search circuit 44 that compares the output of the search circuit 42 with the output from the memory 45 that stores menu item number information corresponding to the movement direction in advance, and outputs the menu item number corresponding to the movement direction; The memory 45, movement direction information I [jA, and movement amount information B are input, and based on the dark value stored in the memory 47 that determines whether the cursor can be moved, it is determined whether the cursor can move to the next menu. X corresponding to the menu item number output from the memory 49 based on the menu item number from the comparison circuit 46 and memory 47 and the search circuit 44
, Y address and select X, Y of the corresponding menu item number.
It is configured to include a search circuit 48 for searching for addresses and a memory 49.

In this embodiment, it is assumed that the cursor is currently located at the menu item ■ indicated by the arrow in FIG. .

Furthermore, the moving direction at this time is assigned to the closest direction among the eight directions indicated by symbols a to h shown in FIG. Therefore, an intermediate movement direction ab=ha between directions a%h is determined, and for example, the movement direction assigned to direction a is ab
The direction of movement is within the range from ha to ha.

The movement ff1i of the mouse 1 within a certain period of time in this embodiment is c
Since it exists between d and de, the direction d is assigned as the moving direction.

When mouse 1 is moved, the amount of movement within a certain period of time is
It is counted by the direction movement amount counter 2 and the Y direction movement amount counter 3, and the value thereof is input to the arithmetic circuit 41 in the menu search section 40.

In the arithmetic circuit 41, if the movement direction information is denoted by A and the movement amount information is denoted by B, the movement direction information A = y / x.

Movement amount information B= , 2 +, and Z are obtained, and movement direction information A is output to the search circuit 42 and comparison circuit 46, and movement amount information B is output to the comparison circuit 46, respectively.

The search circuit 42 compares the value of the movement direction ab-ha, which exists in the memory 43 in advance, with the value of the movement direction information A, and searches in which movement direction range the movement direction information A exists. , one of the directions a w h is output.

The output of the search circuit 42 is sent to the search circuit 44, and the search circuit 44 compares the information of the menu item number corresponding to the movement direction stored in the memory 45 with the output result of the search circuit 42. The menu item number corresponding to the output movement direction is output to the search circuit 48.

The information stored in the memory 45 indicates the positional relationship between each menu item and the adjacent menu item. For example, in the case of menu item
3” in the direction of the direction.

On the other hand, the moving direction information A and the moving amount information B are obtained by the comparison circuit 46.
The comparison circuit 46 determines whether the cursor can be moved to the next menu based on the movable value information stored in the memory 47.

The movable value information stored in the memory 47 indicates the minimum amount of movement in each movement direction a % h for moving from the current menu position to the next menu.

The comparison circuit 46 searches for the minimum amount of movement from the movement direction information A, and compares it with movement amount information B. If movement amount information B is larger, it indicates that movement is possible and a signal of "1" is output, otherwise, it outputs a signal of "1". A signal of 0'' is sent to the search circuit 48.

The search circuit 48 searches for the X and Y address of the menu item position corresponding to the menu item number stored in the memo January 9 based on the menu item number from the search circuit 44 and outputs the comparison circuit 46. If the signal is "1", the searched X and Y address, and if the signal is "0", the X position of the current menu item ■.

Send Y address.

This output is output to the cursor moving unit 6, and the cursor is moved via the cursor moving unit 6 based on this address.

As described above, in the menu item selection operation, the cursor can be moved only between menu items.
