In the CDMA 1x era, the mobile communication business began, and small terminals with input keys for voice communication and SMS were introduced.Soon, technology developed more, and a network for voice communication and data communication was established. It is diversified and the graphics of value-added services are becoming more colorful. As such, small terminals, especially mobile phones and PDAs, which are more convenient and better in performance, use only numeric keys or letter keys for their interface because they are portable, and there is no cursor movement means such as a mouse. It was causing a lot of inconvenience. However, even though these small terminals do not have a mouse, related technologies continue to develop, and various methods for text input, a method for expressing Korean characters, and a number of graphic GUIs have been developed and mounted to facilitate the user interface.

However, since portable information devices do not have a mouse, it is inconvenient because it lacks a function that only a mouse has, that is, a function of directly selecting and moving a desired point on the screen and immediately executing desired application software at that point. Therefore, the game software mounted on terminals such as mobile phones and PDAs can be implemented in a narrower range than the game software running on a general PC.

A computer readable recording medium having recorded thereon a program for executing the method of the present invention described above on a computer (including an information communication device including a mobile phone having a computer function) is provided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the following specification, a terminal of a mobile phone that can be easily carried among various information devices will be described as an example. In particular, a key matrix configured as an input method in which a numeric key of 1 to 9 provided in the mobile phone terminal presses a key is an example. For example, the key matrix will be described as an example in which the numeric keys 123 are arranged from the upper left to the right, and 456,789 are arranged in turn at the lower end thereof. However, if the arrangement of the key matrices is different or the key matrix is set to the capacity, Even if the controlled sensor is configured as an input method through a touch of a finger on the attached key, the main concept of the present invention can be applied, and the technical idea of the present invention is not limited or limited thereto. It may be modified and variously implemented.

1 is a block diagram illustrating a configuration of a cursor moving device using a numeric key according to an embodiment of the present invention. The cursor moving device according to the present invention includes a plurality of numeric keys, a function setting key 11, or a numeric input. A key input section 10 having any one of the 0 to 9 keys set to enable a function switching from the mode to the cursor display mode (ON / OFF), and a display section of the terminal and a cursor display section for outputting a cursor in the screen. 20, a direction / speed setting unit 40 for setting a direction and a speed at which the cursor moves in the display screen, a cursor moving unit 30 for moving the cursor, and each part of the cursor moving device as a whole. It comprises a main control unit 50 for controlling.

The key input unit 10 is provided with a plurality of numeric keys and function keys, and the user can selectively manipulate the input mode for each numeric key into the numeric key input mode or the cursor display mode. A function setting key 11 for switching the function of the operation mode is provided in the key matrix of the terminal.

The cursor display unit 20 checks the operation state of the function setting key operated by the user, and the position of the cursor set to the initial state when the cursor display mode is selected, or by a combination of two numeric keys in the cursor display mode. When there is a cursor movement in the direction, the position of the moved cursor is output in the display screen of the terminal.

In this case, the cursor display unit 20 divides the display screen of the terminal into a screen having a predetermined size and displays a first screen border 300 (refer to FIG. 4A) for displaying the entire area of the display screen, and the divided screen. And a first screen divider 21 for displaying the first guide lines 320 and 330 (refer to FIG. 4A) for distinguishing each other together with the cursor, and the cursor is moved to a position among the divided screens to redisplay the displayed screen. Second guide lines 320-1 and 330-1 (see FIG. 4B) for dividing the divided screens into a screen having a predetermined size, and a second screen for dividing an area of the divided screen into a full screen; And a second screen divider 22 for displaying the screen border 310 (refer to FIG. 4B) together with the cursor.

In addition, the cursor display unit 20 executes a cursor initialization to display a cursor. In this case, the cursor display unit 20 obtains the coordinates Xc and Yc of the initial state of the cursor. The Xc and Yc can be obtained by assuming that the maximum value (W, H or X, Y) of the screen and the cursor are rectangular, and using the size of the rectangle Wc × Hc. 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. Where Wc = W / (number of horizontal axis keys) ^N and 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 like this, initialize the screen. The screen initialization is performed by initializing the 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 is performed, the cursor and the screen are displayed. In this case, the cursor and the screen border may be displayed, and along with the cursor and the screen border, a guideline for facilitating key selection for moving the cursor may be displayed. 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).

An embodiment of the screen initialized as described above is illustrated in FIG. 4A, where reference numeral 300 denotes a first screen border of an initial screen to be divided, and reference numeral 350 denotes an initial state of the initial screen. Reference numerals 320 and 330 denote first cursors for dividing the initial screen vertically and horizontally, respectively. The cursor is preferably in the form of a rectangle, but may be easily identified by the user with the naked eye.

After the screen and the cursor or the screen and the cursor and the guideline are displayed as in 4a, the screen is divided into a predetermined number and the divided information is stored.

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. For example, when the screen size is 90 × 90 and the initial screen is divided into nine small 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 split information is stored, a key input is received. The key uses a numeric key. If numeric keys 1 to 9 are inputted, screen information corresponding to the numbers is read out from the memory. If this is implemented in software, if numeric keys of 1 to 9 are inputted, screen information corresponding to the numbers is read from the memory M ₁ to M ₉ , and the read values are converted into variables x, y, w, h. Assign to

Then, the variable N representing the number of screen divisions is increased by one. 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. The cursor may be located in a predetermined area (center or other predetermined area) of the divided screen.

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, the screen is initialized.

The cursor moving unit 30 directly moves the cursor by the unit moving distance in the moving direction and speed set by the direction / speed setting unit. At this time, the cursor moving unit checks the input time of the second numeric key, which is the second key input among the two numeric keys selected by the user, and if the key input time continues for a specified time or more, The cursor can be moved while maintaining the movement speed.

The direction / speed setting unit 40 checks the first numeric keys and the second numeric keys sequentially selected by the user in the cursor display mode, and moves the cursor in the display screen according to the combination of the two numeric keys. Set the direction and speed to move.

In this case, the direction / speed setting unit 40 sets the first direction as the reference direction and evenly divides the display screen to set several directions. That is, as shown in FIG. 2, after setting the first direction with 0 ° as the reference direction, the display screen is divided into 16 parts equally in the counterclockwise direction, and then 22.5 ° direction, 45 ° direction, 67.5 ° direction, and 90 degrees in order. °, 112.5 °, 135 °, 157.5 °, 180 °, 202.5 °, 225 °, 247.5 °, 270 °, 292.5 °, 315 ° and 337.5 ° will be. This orientation operation is illustrated in FIGS. 2 and 3A-3H.

In addition, the direction / speed setting unit 40 selects either the first speed or the second speed. For example, when the combined two numeric keys are a combination of keys arranged adjacent to each other on a key matrix provided in the terminal, the first speed, which is a reference speed, is set, and the combined two numeric keys are provided in the terminal. In the case of a combination of keys arranged not adjacent to each other on a key matrix, a second speed faster than the first speed is set for a combination of keys arranged in up, down, left, and right diagonal directions, and a second combination of other keys is set. 1 speed is set.
