Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a block diagram illustrating a configuration of a cursor moving apparatus using numeric keys according to an embodiment of the present invention, and includes a screen splitter 100, a numeric key mapping unit 120, and a cursor moving unit 140. .

The screen splitter 100 divides the information device screen into a screen having a predetermined size. When the predetermined screen repartitioning condition is satisfied, the screen splitter 100 divides the divided screen into a screen having a predetermined size again, but preferably repartitions the screen a predetermined number of times. The screen splitter 100 includes a screen information storage unit 10 for storing the divided screen information.

The numeric key mapping unit 120 maps each screen divided by the screen splitter 100 to numeric keys. When the screen is repartitioned, the numeric key mapping unit 120 preferably maps each of the repartitioned screens to a number key.

The cursor moving unit 140 displays the cursor by moving the cursor to a screen, preferably the center of the screen, mapped by the numeric key mapping unit 120 using the numeric keys. The cursor moving unit 140 places a screen border 310 (refer to FIG. 5B) on the cursor position screen moved by the numeric keys mapped by the numeric key mapping unit 120 to distinguish the split screen from the entire screen area. In addition, the cursor movement unit 140 may be guided to distinguish each area of the divided screen for the entire screen divided by the screen divider together with the screen border 310 (320,320-1,330,330-1): 5A and 5B), the display operation of the screen border and the guide line performed by the cursor moving unit may be selectively controlled by using a separate function key provided in the information device. Of course, it can be selectively controlled according to the intention of the information device user. Here, the guide line refers to a virtual line indicating a split position when the screen to be divided is divided once. In particular, the guide line described in the present invention exemplifies a case in which the entire screen is divided into nine divided screens. In this case, it may be preferable to have two vertically divided lines and two horizontally divided lines.

2 is a flowchart illustrating a method of moving a cursor using numeric keys according to the present invention, and the operation of the present invention will be described with reference to FIGS. 1 and 2.

First, the cursor initialization is executed. (Step 200) In the cursor initialization step, the coordinates Xc and Yc of the cursor are obtained. The Xc and Yc can be obtained by using the size of the rectangle Wc x Hc assuming the maximum value (W, H or X, Y) of the screen and the cursor as a rectangle. Here, Wc and Hc are obtained using a variable N indicating the number of screen divisions or using an arbitrary size. Namely, Xc and (Yc) are obtained by Xc = (X-Wc) / 2 and Yc = (Y-Hc) / 2. Wc = W / (number of horizontal axis keys) ^N , Hc = H / (number of vertical axis keys) ^N

For example, if the screen size X × Y is 90 × 90, the cursor size Wc × Hc is 4 × 4, and the screen is divided into nine screens, the coordinates of the cursor are (45,45). The center may be the upper left corner point in a rectangle of a predetermined size. That is, since Xc = (90-4) / 2 = 43 and Yc = (90-4) / 2 = 43, the coordinates of the cursor are (Xc, Yc) = (43, 43). Thus, the cursor information (Xc, Yc, Wc, Hc) = (43, 43, 4, 4).

After initializing the cursor, the screen is initialized (step 210). The screen initialization is performed by initializing variables x, y, w, and h that describe the screen. In the screen information (x, y, w, h), x and y represent the coordinates of the upper left corner of the screen, and w and h represent the size of the divided screen of the screen. The screen's initial values (x ₀ , y ₀ , w _0, h ₀ ) are assigned to the screen variables (x, y, w, h). When N is a variable representing the number of screen divisions, N = 0 is substituted.

For example, when the size of the initial screen is 90 × 90 and the initial screen is one screen, the screen (x, y, w, h) = (0,0,90,90) and N = 0 are initialized.

After the cursor and screen initialization are performed, the cursor and the screen are displayed (step 220). In this embodiment, the cursor and the screen frame may be displayed. In another embodiment of the present invention, a guideline for facilitating key selection for moving the cursor may be displayed together with the cursor and the screen border. The screen border is displayed at a position corresponding to x, y, w, h of the screen using screen information (x, y, w, h), and the border of the cursor is cursor information (Xc, Yc, Wc, Hc). To display on the screen. Here, the X-axis guideline of the guide line is (x, y + h / 3, x + w, y + h / 3), (x, y + 2h / 3, x + w, y + 2h / 3) , Y-axis guideline is (x + w / 3, y, x + w / 3, y + h), (x + 2w / 3, y, x + 2w / 3, y + h).

Each embodiment of the screen initialized as described above is illustrated in FIGS. 3A and 3B. In FIGS. 3A and 3B, reference numeral 300 denotes a first screen border of the initial screen to be divided, reference numeral 350 denotes a cursor whose initial state is set to be located at the center of the initial screen, and reference numerals 320 and 330 denote initial screens. Denotes a first guideline for dividing the vertically and horizontally, respectively. The cursor is preferably in the form of a rectangle.

3A and 3B, after the screen and the cursor or the screen and the cursor and the guideline are displayed, the screen is divided into a predetermined number and the divided information is stored (step 230).

The coordinate value is calculated as shown in Equation 1 from the input screen coordinate information (x, y, w, h) as shown by the numeric keys (123/456/789).

w ₁ = w / 3, h ₁ = h / 3

x ₁ = x, x ₂ = x ₁ + w ₁ , x ₃ = x ₂ + w ₁

y ₁ = y, y ₂ = y ₁ + h ₁ , y ₃ = y ₂ + h ₁

Here, x, y, w, h corresponds to a variable variable when implemented in software.

The calculated coordinate values are stored in the memory M when a dynamically or statically allocated memory is called M. The memory M corresponds to the screen information storage unit 10 described above. For example, when the size of the screen is 90 × 90 and the initial screen is divided into nine smaller screens, nine screens M ₁ to M ₉ may be described as follows. have.

M ₁ (x ₁ , y ₁ , w ₁ , h ₁ ) = M ₁ (0,0,30,30)

M ₂ (x ₂ , y ₁ , w ₁ , h ₁ ) = M ₂ (30,0,30,30)

M ₃ (x ₃ , y ₁ , w ₁ , h ₁ ) = M ₃ (60,0,30,30)

M ₄ (x ₁ , y ₂ , w ₁ , h ₁ ) = M ₄ (0,30,30,30)

M ₅ (x ₂ , y ₂ , w ₁ , h ₁ ) = M ₅ (30,30,30,30)

M ₆ (x ₃ , y ₂ , w ₁ , h ₁ ) = M ₆ (60,30,30,30)

M ₇ (x ₁ , y ₃ , w ₁ , h ₁ ) = M ₇ (0,60,30,30)

M ₈ (x ₂ , y ₃ , w ₁ , h ₁ ) = M ₈ (30,60,30,30)

M ₉ (x ₃ , y ₃ , w ₁ , h ₁ ) = M ₉ (60,60,30,30)

After the screen is divided and the partition information is stored, the key is input (step 240). The key uses a numeric key. If numbers 1 to 9 are input (step 250), the screen information storage unit 10 reads the screen information corresponding to the number by the number key mapping unit 120. When implementing them by software, if the 1-if to 9 numeric key is input (250 steps), the numeric key mapping unit 120 memory for screen information corresponding to the number stored in the 230 step by (M ₁ - M ₉ ) and the read value is substituted into the variables x, y, w and h.

The variable N representing the number of screen divisions is increased by one (step 260).

In addition, a cursor (or a cursor and a screen border, or a cursor and a screen border and a guideline) is displayed on a screen corresponding to the read screen information. (Step 220) The cursor is a predetermined region (center or advance) of the divided screen. May be located in other designated areas).

At this time, after comparing whether the N value is larger than the preset maximum value Nmax, and if the N value is smaller than Nmax, the Xc and Yc coordinates of the cursor to be centered from the screen information (x, y, w, h) The screen is calculated by calculating the value and displaying it again. If the N value is equal to the Nmax value, go to step 210 and initialize the screen.

5A through 5C illustrate screen splitting when N = 2, and are divided into second and second guide lines 320 and 330 in the first divided screen as mentioned through an embodiment of the present invention. An example of a state in which the second guide lines 320-1 and 330-1 of the screen are displayed is shown. 5A illustrates an initial setting state in which the cursor 350 is positioned at the lower left side (more specifically, the third key division area of the corresponding key number 7 area) on the initial screen of FIG. 5A, and the initial position of the cursor is Of course, this may vary depending on the settings of the settings or the application program.

As shown in FIG. 5A, when nine screens are divided using two horizontal guide lines 330 and two vertical guide lines 320, the numeric keys are positioned in the initial seventh key area. When '3' is pressed, the second screen border 310 and the second guide lines 320-1 and 330-1 are displayed in the divided area mapped to the 3rd key as shown in FIG. If the '1' is pressed within, the cursor 350 moves to the first key area in the third key area as shown in FIG. 5C, and the second screen border 310 and the second screen displayed in FIG. The guide lines 320-1 and 330-1 are removed from the screen, and the first screen border 300 and the first guide lines 320 and 330 are displayed together with the cursor 350 on the screen.

On the other hand, when the key is input in step 240, if a numeric key is not input for a predetermined time or if a key other than the numeric key is input in step 250, the cursor movement and screen division are stopped and finished, and then other functions are performed or the screen is terminated. Go to the initialization phase. For example, if '0' is input immediately after the first numeric key input, the second or third numeric key input, and the game program is a missile game, the action corresponding to the firing may be performed.

The present invention can be embodied as code that can be read by a computer (including all information communication devices having an information processing function including a mobile phone) on a computer-readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording devices include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like.
