Abstract

PURPOSE:To enable plural kinds of cursor control with one key by providing a cursor position changing means which determines a target cursor position according to a cursor current position from a storage means at the time of key operation and a cursor conversion table corresponding to a cursor control code. CONSTITUTION:When an input data decision circuit 2 decides a cursor control code (d) by cursor key operation, a cursor position converting means 3 selects a cursor position conversion table (c) corresponding to the code (d) from a cursor position conversion table group 4. Then the cursor current position at the time of key operation is read out of the cursor position storage mechanism 6 to refer to a table C and when a cursor movement destination Z and Y coordinates 421 and 422 are entered in a movement destination definition part 42, the mechanism 3 uses those values, but when not, movement destination coordinates are determined according to movement calculation flags 423 in the table C. Consequently, plural kinds of cursor control are easily performed by one-cursor-key operation.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a cursor control system, and particularly to devices with compact keyboards, such as general text processing devices and word processors, which can control various cursors using a small number of keys. This invention relates to a cursor control method to enable control.

[Conventional technology]

Traditionally, this type of cursor control method is
Only one cursor movement rule was defined for each key.

[Problem to be solved by the invention]

Conventional cursor control methods require a large number of cursor control keys to realize a wide variety of cursor control functions, but it is not possible to install all cursor control keys on a miniaturized keyboard. , cursor control functionality was limited.

In addition, in order to move the cursor to the desired position on the display device, it is necessary to operate multiple cursor control keys, so it is necessary to look at the display device to confirm the current cursor position, and then to control the cursor. It was necessary to look at the keyboard alternately in order to imitate the keys, which had the disadvantage of deteriorating operability.

[Means to solve the problem]

The cursor control method of the present invention includes a cursor position conversion table that defines, for one cursor control key, the cursor position at the time when that key is specified and the desired cursor position, the cursor control key, and the cursor position. The cursor position conversion means controls the conversion table.

〔Example〕

Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

First, input data a input from the keyboard 1 is passed to the input data determination mechanism 2.

The input data determination mechanism 2 determines the received input data a according to internal determination criteria, and if the input data a is the cursor control key code d, it is passed to the cursor position conversion control function 3.

The cursor position conversion control function 3 first searches the cursor position conversion table group 4 defined for each cursor control key code, and searches the cursor position conversion table group 4 for the cursor control key code d received from the input data determination mechanism. Load C.

Here, an overview of the cursor position conversion table will be explained.

FIG. 2 shows the structure of the cursor position conversion table.

The cursor position conversion table is composed of a cursor position definition section 41 for determining the cursor position at the time when the cursor control key is pressed, and a movement destination definition section 42 for defining the movement destination of the cursor.

The cursor position definition section 411 indicates the range of the X coordinate of the cursor position, and 412 indicates the range of the Y coordinate of the cursor position.

The destination definition section 42 defines the X coordinate 4 of the cursor position of the destination.
21, Y coordinate 422, and destination calculation flag 423.

Next, a cursor position conversion procedure using this cursor position conversion table will be explained.

The cursor position conversion mechanism 3 reads the cursor position 6 (X, Y coordinates) at the time when the cursor control key is operated from the cursor position storage mechanism 5.

Then, it compares with the cursor position definition part of the cursor position conversion table C that has already been read, and determines the corresponding movement destination definition part.

Next, if the X and Y coordinates are defined in the destination definition section, this coordinate e is passed as is to the cursor display control section 6 to display the cursor.

If the X and Y coordinates are not defined in the destination definition, the destination calculation flag calculates the destination position according to a predetermined procedure and passes it to the cursor control unit.

〔Effect of the invention〕

As explained above, according to the present invention, multiple cursors can be controlled with a single cursor operation key, so even a device equipped with a small keyboard with few keys can realize various cursor operations, and it is also possible to perform cursor operations. Also, when positioning the cursor at a target position, the number of keys to be operated can be reduced, which has the effect of improving ease of imitation.
