The present invention relates to a method for providing a software pointing input function, a wireless communication terminal using the same, and a computer-readable recording medium having recorded thereon a program for implementing the method. By implementing the pointing input function provided in software, a method of providing a software pointing input function and a wireless communication terminal using the same to enable a hardware independent application development and to provide a variety of user methods in pointing input and A computer readable recording medium having recorded thereon a program for realizing the method.

In the present invention, a wireless communication terminal is a mobile communication terminal, a personal mobile communication terminal (PCS), a personal digital terminal (PDA), a smart phone, a next generation mobile communication terminal (IMT-2000), such as a wireless terminal while carrying a person A terminal capable of wireless communication.

Here, the wireless communication refers to a function of transmitting / receiving various data including multimedia such as text, voice, and video. In other words, as the wireless communication terminal becomes more functional, it provides high-speed, high-capacity data communication, such as digital content downloading and multimedia message transmission, as well as voice calls. In addition, with the recent convergence of wireless communication terminals, schedule management functions and document editing functions have been added to wireless communication terminals, thereby providing a user with functions almost similar to those of a personal desktop.

Due to the data communication and personal information management functions as described above, the input / output interface of the wireless communication terminal has also been developed accordingly, and as a result, it now provides a pointing input function. Here, the pointing input function refers to an input function for precisely specifying an input position by moving a cursor such as a mouse that is often used in a desktop and a touch screen for pressing a button displayed on a screen.

Meanwhile, the user input method may be variously implemented depending on which function is a relatively important function among various functions simultaneously mounted in the wireless communication terminal. In addition, different hardware configurations are required depending on the type of input method to be implemented. For example, when a personal information management function or a function related to multimedia data communication is implemented as a core function of a wireless communication terminal, a touch screen for pointing input is more preferably applied to the terminal. In this case, since the keypad input method is basically implemented together and the size of the LCD screen is increased for the output of personal information or multimedia data, the size of the terminal becomes relatively large.

However, when the input method of the wireless communication terminal is implemented in various ways, the hardware configuration is different for each wireless communication terminal, and accordingly, there is a problem in that work efficiency during software development is reduced.

Here, looking at the development process of the software mounted on the wireless communication terminal, most of the wireless communication terminal software (eg, application) is first implemented on the desktop on which the development software is mounted. In this case, the desktop mouse is the main input device.

Subsequently, subsequent development work may vary depending on whether the touch screen for pointing input is included in the wireless communication terminal. That is, in the case of the wireless communication terminal including the touch screen, the input signal by the mouse is replaced by the input signal through the touch screen, and the combination of key input using the touch screen and the keypad and additionally processes the expected key input signal. You need to implement additional routines.

In the case of a wireless communication terminal that does not include a touch screen, the input signal using a mouse is replaced only with an input signal using a keypad (numeric keys, various function keys, etc.). You have to think.

In other words, in terms of software development, since the development work must be performed in accordance with each hardware configuration of the wireless communication terminal, there is a problem in that the portability of the application decreases and the developer takes more time to develop new products.

In addition, in the case of a wireless communication terminal, a pointing input function is implemented only through an input method through a touch screen, which is a hardware device, and when using a wireless communication terminal without a touch screen, personal information management functions and various functions related to multimedia are provided. There was a problem causing inconvenience to use the back. In addition, a user input method is limited to a pointing input method using a touch screen.

The present invention has been proposed to solve the above problems, and by implementing a pointing input function provided by a mouse, a touch screen, etc., which is a hardware device, enables hardware independent application development and pointing in various ways. It is an object of the present invention to provide a method of providing a software pointing input function for providing an input function to a user, a wireless communication terminal using the same, and a computer-readable recording medium having recorded thereon a program for realizing the method.

There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention implements the existing pointing input function using a hardware device (eg, a mouse or a touch screen) in software, thereby improving the portability of the software and providing the user with more various pointing input methods.

In the following detailed description, a case where the software pointing input function according to the present invention is applied to a wireless communication terminal will be described as an example. That is, a case where a pointing input function is implemented using a keypad (numeric keys, function keys, side keys, etc.), which are general input devices mounted on a wireless communication terminal, will be described in detail as an example.

1 is a configuration diagram of an embodiment of a wireless communication terminal having a software pointing input function according to the present invention.

As shown in FIG. 1, a wireless communication terminal having a software pointing input function according to the present invention stores a wireless transmitter / receiver 11, a pointing input mode program, and the like for transmitting / receiving a wireless signal with an external device. The input unit (keypad) 13 and the controller 15 for receiving input of a storage input unit 12, a pointing input mode switch request signal from a user, various pointing input signals for moving the cursor and executing a menu in the pointing input mode, and the like. The pointing input mode program stored in the storage unit 12 is stored in response to receiving a pointing input mode switching request signal through the display unit (LCD) 14 and the input unit (keypad) 13 for outputting various screens according to the control of the control unit. It operates by switching to the pointing input mode, moving the cursor according to various pointing input signals received through the input unit (keypad) 13, and operating various menus. The control unit 15 to perform the operation, the signal received from the wireless transmission and reception unit 11 under the control of the control unit 15 converts the voice to the voice output unit (speaker) 17, and outputs the voice input unit (microphone) A codec 16 for converting the voice received from the signal 18 into a signal and transmitting the signal to the control unit 15 to be transmitted through the wireless transmitter / receiver 11, received from the codec 16 A voice output unit 17 for outputting a voice, and a voice input unit (microphone) 18 for receiving a voice and delivering it to the codec (CODEC) (16).

At this time, in the present invention, the control unit 15 controls the overall operation of the wireless communication terminal, and at the same time to operate the pointing input mode program to provide a pointing input function of the software by operating. That is, by operating by switching the input mode to the pointing input mode, the pointing input is possible even if a hardware device such as a touch screen is not provided. In addition, the controller 15 provides both a general input mode and a pointing input mode, and enables the user to select the input mode according to the preference by allowing the two input modes to be switched between each other. For example, when a user wants to make a voice call, the user may select a general input mode, and when a user wants to manage a personal schedule, a pointing input mode that is more suitable for the schedule management task may be selected.

In detail, the control unit 15 drives the pointing input mode program stored in the storage unit 12 in response to receiving a pointing input mode switch request signal through the input unit (keypad) 13 while operating in the normal input mode. Let's do it. Then, a cursor (which may be an arrow-shaped pointer) for pointing input through the display unit (LCD) 14 is output to a preset position (for example, the center of the screen), and input through the input unit (keypad) 13. In response to various pointing input signals received, the output cursor is moved to execute a menu selected by the user. That is, the controller 15 operates in a pointing input mode, not a normal input mode, and receives a signal through the input unit (keypad) 13, but receives a request (general operation in a wireless communication terminal) requested by a user. Perform the same as in (if, of course, if the selected operation is implemented to be performed in any one input mode, it is performed in the corresponding input mode). In this case, the pointing input signal is a request signal related to movement of a cursor, selection of a menu or an item (eg, a registration schedule item), and execution of a menu. Thereafter, the controller 15 operates by switching to the normal input mode in response to receiving the general input mode switch request signal (more precisely, the pointing input mode release request signal) through the input unit (keypad) 13 (that is, Release the pointing input mode).

Here, referring to the output and movement process of the cursor in more detail, the controller 15 first outputs the cursor to the corresponding position according to the setting matters related to the pointing input mode. For example, the center of the screen may be its position. Then, the cursor is moved in accordance with a pointing input signal (here, a signal for moving the cursor) from the user through the input unit (keypad) 13.

In this case, the pointing input signal for moving the cursor is an input signal of various keys (for example, numeric keys) included in the input unit (keypad) 13, and indicates information about a moving direction and a moving distance of the cursor. . Here, the movement direction of the cursor may be set to be divided into east / west / south / north / southeast / northeast / southwest / northwest, and the like, and the moving distance may be a moving distance in pixels. At this time, in the case of the movement direction, for example, each numeric key and each movement direction may be set to correspond to each other. That is, the numeric keys surrounding the numeric key "5" with the numeric key "5" as the center may be set to represent one moving direction. If the numeric key "2" is set to indicate the north direction, the cursor moves from the initial position (e.g. in the center of the screen) by the preset distance in pixels each time the user presses the numeric key "2" once. You will move north. At this time, the numeric key "5" located at the center may be set to serve as an enter key. That is, if the other numeric keys around each are set to indicate one direction of movement, the centrally located numeric key " 5 " selects a menu / item (e.g., a phone number entry registered in the phone book), and a signal for executing the menu execution Can be used for input.

Here, it is preferable to provide a predetermined menu so that the user can freely set a moving distance in units of pixels moving according to one key input and a button (for example, a numeric key) of a keypad matched with each moving direction. Do.

In another embodiment, when the control unit 15 receives the pointing input mode switch request signal through the input unit (keypad) 13, the input of the pointing input mode switch request signal is not performed instead of completely switching the input mode. While this is being held, the key input signal input through the input unit (keypad) 13 may be recognized as a pointing input signal. In this case, the user must keep pressing the corresponding button (eg, side key) for inputting the pointing input mode switch request signal. That is, the cursor output through the display unit (LCD) 14 may be moved through a pointing input using a numeric key while the pointing input mode switching key is pressed.

On the other hand, the storage unit 12 stores the operation program and the system program of the control unit 15, the operation program and the system program is stored in the normal ROM (ROM) area and can be erased as necessary. The storage unit 12 also includes a RAM for temporarily storing data generated during execution of various operation programs. The storage unit 12 also stores a pointing input mode program for providing a pointing input function in software. In addition, it stores a graphic library and a device driver for supporting a graphical user interface (GUI) in the pointing input mode. A more detailed description thereof will be described later with reference to FIG. 5.

The input unit 13 includes a plurality of numeric keys (letter keys), menu keys, and function keys for performing various functions, and outputs key data to the controller 15 according to external operations. In addition, the input unit 13 may include signals related to the switching of the input mode (ie, a pointing input mode switch request signal and a general input mode switch request signal), movement of a cursor, selection of a menu or item, and execution of a menu in the pointing input mode. It is used to receive various pointing input signals. In this case, it is preferable to match the various numeric keys with the movement direction (east / west / south / north, etc.) of the cursor so that the cursor can be moved using the numeric keys. Of course, instead of numeric keys, function keys such as arrow keys and general keys can be used.

In addition, the input unit (keypad) 13 allows the cursor to move at once according to a setting signal for various detailed operations in the pointing input mode, that is, a direction of movement of the cursor and a numeric key corresponding thereto, and a single numeric key input. A setting signal for a moving distance (which may be a moving distance in pixels) or the like is received. That is, the user may set various items related to the movement of the cursor in the pointing input mode by using a predetermined menu.

The display unit 14 is a display device such as a liquid crystal display (LCD). The display unit 14 displays the state of the wireless communication terminal, the progress of the program, and the like under the control of the control unit 15. That is, the overall state of the wireless communication terminal and the contents received are displayed. In addition, the display unit 14 outputs a cursor in a pointing input mode under the control of the controller 15, moves and outputs the cursor according to a pointing input signal, and provides a graphic interface related to the pointing input.

2 is a flowchart illustrating a method for providing a software pointing input function in a wireless communication terminal according to the present invention. Here, a case in which the pointing / general input mode is switched to each other by a toggle method to operate in any one input mode will be described.

First, as the control unit 15 receives a pointing input mode switch request signal through the input unit (keypad) 13, the controller 15 drives the pointing input mode program stored in the storage unit 12 to the pointing input mode. (202). That is, in the normal general input mode, the key input through the input unit (keypad) 13 is switched to the pointing input mode that recognizes the pointing input to operate. At this time, the controller 15 outputs a cursor to a predetermined position, for example, the center of the screen, so that the user can move the cursor to a desired point.

Subsequently, the controller 15 moves the output cursor to a corresponding position (preset moving direction and moving distance) according to various pointing input signals input through the input unit (keypad) 13, for example, an input signal for a numeric key. Then, perform a general operation (ie, a task requested by the user) in the wireless communication terminal, such as outputting an item selected by the user or executing a menu (203). For example, it may include outputting a phone number entry registered in the phone book or outputting a screen related to Internet browsing.

Subsequently, the controller 15 receives the input mode from the pointing input mode to the normal input mode in response to receiving the general input mode switch request signal (more accurately, the pointing input mode release request signal) through the input unit (keypad) 13. Switch (release the pointing input mode) (204). In this case, the input of the normal / pointing input mode switch request signal may be the same key input signal. For example, side keys may be used for input of the normal / pointing input mode switch request signal.

That is, the controller 15 switches the input mode to a toggle method according to the input of the normal / pointing input mode switch request signal, thereby operating in one of the general input mode and the pointing input mode.

3 is a flowchart illustrating another embodiment of a method for providing a software pointing input function in a wireless communication terminal according to the present invention. Here, a case in which the operation of the pointing input mode switching request signal is temporarily operated while the input of the pointing input mode is maintained will be described.

First, as the controller 15 receives an arbitrary signal through the input unit (keypad) 13 while operating in the normal input mode (301), it determines whether it is an input signal for the pointing input mode switch key. (302). Here, the pointing input mode switch key may be a side key.

When the first input signal determination result 302 is an input signal for the pointing input mode switch key (ie, a pointing input mode switch request signal), the cursor operates in the pointing input mode to move the cursor to a preset screen position (for example, Center) (303). Then, the cursor is moved according to the input signal of the numeric key for moving the cursor, and the requested operation is performed. (For example, launch the requested menu).

Meanwhile, when the first input signal determination result 302 is not an input signal for a pointing input mode switch key, whether the received arbitrary signal is an input signal for a preset numeric key related to the movement of a cursor. Determine (304). Of course, when the direction key, not the numeric key, is set to indicate the direction of movement of the cursor, it is determined whether the received arbitrary signal is an input signal to the direction key.

As a result of the second input signal determination 304, in the case of the numeric key, it is determined whether it is a pointing input mode (that is, whether or not the pointing input mode switch key is pressed) (305) in the pointing input mode. In step 306, the cursor is moved according to the received numeric key. In addition, a task generally performed (ie, a task requested by a user) is performed in the pointing input mode such as execution of a menu. On the other hand, in the non-pointing input mode (in the normal input mode), the existing general key input processing is performed (307).

On the other hand, when the second input signal determination result 304 is not an input signal for the numeric keys, the process proceeds to the existing general key input processing process 307.

It is assumed that the process of temporarily switching to the pointing input mode according to the input of the pointing input mode switch key as described above is implemented using one keypad device driver.

4 is a diagram illustrating an embodiment of switching to a pointing input mode and a screen configuration according to the wireless communication terminal according to the present invention.

As shown in " 41 ", the user can enter various menus such as phonebook search, call origination, schedule registration, etc. through input of menu keys, function keys (e.g., direction keys), numeric keys (letter keys), etc. in the normal input mode. You can run The pointing / general input mode switching key is implemented as one of the side keys. That is, the operation of switching the pointing / general input mode to each other in a toggle method is repeated. Of course, the input signals for the different keys instead of the same key may be implemented as the pointing input mode switch request signal and the general input mode switch request signal.

While operating in the normal input mode, the pointing / general input mode switching key is pressed to switch from the conventional general input mode to the pointing input mode (" 42 "). That is, the pointing input mode program is driven and an arrow-shaped cursor is output at a preset screen position, here, the center of the screen, so that accurate coordinates can be designated by moving the cursor. The user can execute a menu desired by moving the output cursor to a specific position and selecting the corresponding menu.

Looking at the movement of the cursor in more detail with reference to "42", it is a preset state to match the movement direction of the cursor and each number key correspondingly. For example, in the case of the numeric key "2", the state is set to indicate the north, in the case of the numeric key "7", the state is set to indicate the southwest, while in the case of the numeric key "5" located in the center of the keypad. It is set as an enter key (necessary for input of a menu / item selection signal and menu execution request signal, etc.). Of course, it is obvious that the cursor can be set to move by using not only numeric keys but also direction keys and other function keys. It is preferable to provide a predetermined menu for the user to set the moving direction of the cursor and the corresponding numeric key (or other key) corresponding thereto.

In addition, in order to more easily move the cursor output at a predetermined screen position (for example, the screen center) in a desired direction as the pointing input mode is switched, each display unit (LCD) 14 (14). Can also be indicated by an arrow At this time, the cursor is moved by a predetermined movement distance in units of pixels. The cursor may be moved to a desired position by inputting a number key corresponding to a desired movement direction several times.

Thereafter, as the point / general input mode switch key is re-entered, the input mode switches from the pointing input mode to the normal input mode.

5 is a diagram illustrating an embodiment of a key input signal processing process for providing a pointing input mode in a wireless communication terminal according to the present invention.

As illustrated in FIG. 5, the process of switching to the pointing input mode may be implemented by using a separate pointing input mode switch key device driver.

That is, the switching to the pointing input mode according to key input and various operations in the pointing input mode may be implemented using one device driver, that is, the keypad device driver for the entire keypad, or the device for the pointing input mode switching key. It may be implemented by separately configuring a driver (or interrupt handler). In this case, the pointing input mode switch key may be a button for switching between the pointing / general input modes in a toggle manner. When the device driver for the pointing input mode switch key is implemented separately, a general key device driver for the general key except for the pointing input mode switch key is required.

Here, it is apparent that the X windows and the X library are not limited thereto as an example of a general graphic processing library.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

The present invention as described above, by implementing the pointing input function in software, it is possible to develop an application independent of hardware, and there is an effect that can provide a more various pointing input method to the user.

That is, the present invention implements and provides a pointing input function provided by a hardware device such as a mouse or a touch screen in software, so that the application can be developed independent of hardware assuming the same use environment regardless of hardware support. In addition, by using the keypad, which is currently the main input device, by moving the cursor to enable pointing input, it is possible to provide a user with a more various pointing input function.
