According to the present invention, a pointer using a wheel is modified by modifying a corresponding source in a mobile phone operating source using a pointer implemented in a personal computer (PC) using an auxiliary input device (Mouse, etc.). Pointer), and in terms of hardware structure, it is possible to add an additional interface in addition to the keypad by mounting only two wheels.

There is no code for pointers in existing cell phone operating sources, such as Qualcomm Source. Therefore, for the present invention, modification of the corresponding source code is inevitable, and the processing of the source code of the image display function and the wheel detection function is performed in the handset task (HS) task. It can be implemented in a mobile phone by inserting it.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

That is, the present invention allows the user to use an external input device such as a wheel while checking the pointer displayed through the display unit 14.

2 is an exemplary configuration diagram of a mobile phone including a wheel in a method of providing a pointer service in a mobile phone screen according to the present invention.

 In order to achieve the method of providing a pointer service on a screen of a mobile phone according to the present invention, an operation inside / outside the mobile phone is required. First, there must be an external input device such as a wheel that can be used externally connected to a mobile phone. In addition, it is necessary to implement a pointer on the screen internally and to perform processing according to the positional change of the corresponding pointer on the screen and key input according to an input signal from an external input device such as a wheel.

Here, a mobile phone having a vertical scroll wheel positioned on the left side of the mobile phone and a horizontal scroll wheel positioned on an upper side when viewed from the front as shown in FIG. 2 is provided. In this way, vertical scrolling and side scrolling can be handled accurately according to the user's intention.

However, the method of providing a pointer service in a mobile phone screen according to the present invention is not merely applied to a mobile phone implemented in this manner. Like a conventional computer mouse, each scroll may be integrated into one ball or sensor. Other ways may be used.

3A to 3C are diagrams illustrating one embodiment implemented in a mobile phone in the method of providing a pointer service in a mobile phone screen according to the present invention.

3A to 3C show the pointer service providing method in the mobile phone screen according to the present invention actually implemented on the screen of the mobile phone. As shown in the figure, by implementing the pointer on the mobile phone screen, the mobile phone screen can be used more effectively.

In detail, FIGS. 3A to 3C show a demonstration scene of a game application using a mouse pointer.

The method of providing a pointer service in a mobile phone screen according to the present invention will be described below.

Mouse pointer image control module and display module (Mouse pointer) in a handset task (HS task (hsg.c)) of Qualcomm Source, one of mobile phone operating sources, to implement a wheel pointer according to the present invention. Image control / display module was added, and an event, command queue module, and dispatcher module were created and inserted to use a mouse pointer.

Looking at this in detail.

The image output of the wheel pointer should be prioritized on a liquid crystal display (LCD), which is a typical screen of a mobile phone, so it is a function of the lowest layer to output to the LCD. Include the module associated with the pointer image inside.

The function that contains the module stores the image in a buffer that allocates space corresponding to the size of the image where the pointer image is to be placed.

The pointer image is then moved to a screen buffer for screen output. The pointer image on the LCD is then displayed by displaying it on the LCD of the phone and moving the image before the pointer image stored in the buffer to the screen buffer to restore the original image. Pointer Image) Output is complete.

Movement of the wheel pointer changes the values of the X and Y axes by inserting a module that detects the movement of the wheel into the handset task (HS Task (hsg.c)).

 Then, to enable the application of the wheel pointer, an event function that can be performed inside the start x, y coordinates and the end x, y coordinates is added to the queue. Insert a dispatch / execute module.

4 is a flowchart illustrating a method for providing a pointer service in a mobile phone screen according to the present invention.

The present invention is to implement a pointer on the screen of the mobile phone as described above to enable the user to use it. To this end, an external input device such as a wheel or a mouse that can use a pointer is required, and the pointer can operate according to a command from the external input device.

In this state in which the pointer can operate, a pointer and a background image are displayed on the screen, and an event generated by a user using the pointer is required.

Referring to the flow of the drawing, the display of the image including the pointer and the processing according to the occurrence of an event are as follows.

First, the mobile phone stores the image corresponding to the place where the pointer image is to be stored in a buffer previously secured (401). That is, to save the original screen before the pointer.

The pointer image is moved to a screen buffer for screen output (402). The screen buffer holds information about the image that appears on the phone's screen. The screen buffer now has an image that contains a pointer that will appear on the phone's screen.

Next, the mobile phone screen image including the pointer image in the screen buffer is displayed on the screen of the mobile phone (403). Then, the image previously stored in the buffer is moved to the screen buffer to restore the original image before the pointer image (404).

In this way, the pointer is displayed on the screen of the mobile phone.

Next, we look at the process of event occurrence.

After displaying the pointer image on the screen of the cellular phone, the controller waits until an event related to the pointer occurs, and then checks the occurrence of the event through the pointer (405). Events generated through the pointer include a focus event generated when the pointer is located at a specific position, a click event generated when the user presses an external input device such as a wheel or a mouse, and a pointer movement event according to the movement of the pointer.

If there is an event occurrence through the pointer, it is checked whether it is a focus event (406). As a result of the check, if the focus event is correct, the focus is located at the corresponding position and dispatched to execute the event (407). The process waits again until an event related to the pointer occurs, and then repeatedly performs the event occurrence process 405 related to the pointer.

As a result of checking whether the focus event is a focus event, whether an event related to a pointer is a click event is analyzed in step 408.

As a result, if the click event generated by the user clicking the wheel, mouse, etc. is correct, the event is dispatched based on the user's click information to execute the event (409). The process waits again until an event related to the pointer occurs, and then repeatedly performs the event occurrence process 405 related to the pointer.

As a result of analyzing whether it is a click event, if it is not a click event, it is confirmed that the movement event is caused by the movement of the pointer (410). The process is repeated from step 401 of storing the buffer.

Next, a function for implementing a function of a pointer service in a method of providing a pointer service on a screen of a mobile phone according to the present invention will be described, and the implemented function will be described.

Table 1 below describes the function implementation functions.

boolean mouse_put_event (mouse_event_type e) Function to add mouse event in buffer void mouse_delete_event_all (void) Function to remove mouse event in buffer void mouse_execute_event (void) click event dispatcher void mouse_onFocus_event (void) event dispatcher when focus is located void SaveScreen2Buffer (word * pwDest, word * pwSrc) A function that backs up the part where the mouse image is to be output to the buffer void DisplayMouseImage (word * pwDest, const word * pwSrc)  Write mouse image to display buffer void RestoreScreenBuffer (word * pwDest, word * pwSrc) Function to recover the original background part

Next, look at the function implemented by the above function based on the above [Table 1].

First, a mouse image, i.e. a pointer image, must be displayed above all images. Therefore, image processing and wheel detection are performed in the handset task (HS Task).

Secondly, changing the wheel value in the handset task (HS task) handles signal processing between tasks for the pointer's x, y-axis translation and pointer move events. This is done by sending the child to a UI task.

Third, a pointer is operated in an event driven manner for convenience of use, and an event enables a user to directly enter a queue.

Fourth, an event may be treated as a click event and a focus event. The event may be dispatched when a pointer is clicked or positioned at the point. event).

Finally, the Event Queue accepts only certain events using an array rather than a linked list due to the limitations of the phone memory.

In summary, the mobile phone implements a pointer on a screen, receives a pointer-related command from a user, and executes a corresponding event accordingly.

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

The present invention as described above, by implementing the pointer on the mobile phone screen has the effect that the user can efficiently use the display screen widened in place of the keypad interface of the existing mobile phone.

In addition, the present invention broadens the application field of a mobile phone that becomes a personal digital assistant (PDA) by implementing a pointer on a mobile phone screen, and affects application contents performed on a virtual machine. There is an effect that can create a new content market associated with it.

According to the present invention, a pointer using a wheel is modified by modifying a corresponding source in a mobile phone operating source using a pointer implemented in a personal computer (PC) using an auxiliary input device (Mouse, etc.). Pointer), and in terms of hardware structure, by mounting only two wheels, it is possible to add an additional interface in addition to the keypad, so that the user can conveniently use it.
