DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1A through 5, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged electronic device. Exemplary embodiments of the present disclosure will be described herein below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the disclosure in unnecessary detail. Also, the terms used herein are defined according to the functions of the present disclosure. Thus, the terms may vary depending on user's or operator's intension and usage. That is, the terms used herein are to be understood based on the descriptions made herein.
Hereinafter, a method and apparatus for designating an entire area by using a partial area touch in a portable device will be described. In the present disclosure, the portable device includes a smart phone, a tablet computer, portable devices capable of receiving a touch input, and devices capable of receiving a touch input.
The present disclosure relates to a method and apparatus for designating an entire display area by using a touch on any partial area included in the entire display area when it is difficult for a user to touch the entire display area with one hand in a portable device having a large display screen such as a smart phone or a tablet computer.
The portable device of the present disclosure divides a display screen into several parts according to a specific length or distance reachable by a thumb of a user who holds the portable device.
The portable device of the present disclosure can start and perform a screen movement request function of the user by recognizing a specific pattern of a touch input of a thumb or a finger of the user.
In the present disclosure, the specific pattern is a predetermined pattern capable of recognizing that the portable device performs the display screen movement function. In the present disclosure, a display screen movement request type and a screen movement range may vary depending on horizontal and vertical sizes of a display of the portable device. That is, the present disclosure determines the number of the divided display screens according to horizontal and vertical sizes of the display of the portable device. Alternatively, the number of divided display screens can be determined to any number N according to a user or manufacturer.
That is, if the display is relatively small in size, the display may be divided into two parts and each half screen may move up and down or left and down. If the display is large in size, when the portable device displays a numeric number corresponding to a number assigned to a divided display area after the user requests to move the display screen, the user can designate the divided display screen by the use of a touch input and can request to move the screen.
When the user requests to move the divided display screen, a desired divided display screen moves in a range reachable by a user's finger and a popup for requesting the touch input is displayed in the display screen.
After the divided display screen moves, if there is another touch input of the user, a size of the display area returns to an original size while performing a function for indicating the touch input.
The aforementioned process is described below with reference to the accompanying drawings.
FIGS. 1A through 1E illustrate a display screen that is divided into two parts according to an embodiment of the present disclosure.
Referring to FIGS. 1A through 1E, if a user holds a portable device with one hand and an input window for a user input is located in an upper part of the display screen (FIG. 1A), the portable terminal receives a touch input on a predefined specific pattern to move the display screen from the user (FIG. 1B). Although “N” is used as the specific pattern in the present embodiment, it is apparent that the specific pattern may include other types of pattern.
If the portable device detects the specific pattern touch input, the portable device moves downwards an upper part of the display screen (FIG. 1C). When the upper part of the display screen moves downwards, the portable device can display an input request text to the upper part of the display screen (FIG. 1D). Alternatively, the portable device can display the number of text messages currently received or the number of e-mails currently received to the upper part of the display screen.
When the user provides the touch input to the input window of the upper part of the display screen, the portable device can display an input screen in response to the touch input, and can wait for a subsequent input (FIG. 1E).
FIGS. 2A through 2G illustrate a display screen that is divided into a number of equal parts according to an embodiment of the present disclosure.
Referring to FIGS. 2A through 2G, the number of equal parts may be nine parts for example.
If a user holds a tablet computer with one hand, an icon 210 for a user input is located in an upper left portion of the display screen, and a display screen area 220 in which a user input can be made by using a user's finger is located in lower right part (FIG. 2A), then the tablet computer receives a touch input on a specific pattern predefined for a display screen movement in the display screen area 220 in which input can be made (FIG. 2B). Although “N” is used as the specific pattern in the present embodiment, it is apparent that the specific pattern may include other types of pattern and the specific pattern may inputted in the display screen area 220 in which input can be made and may inputted in any other display screen area.
Thereafter, if the tablet computer detects the specific pattern touch input, the tablet computer displays a screen divided into (N+1) equal parts (FIG. 2C). Although N is set to 8 in the present embodiment, the value N can be predetermined by a vendor, a manufacturer, or a user. Alternatively, the user can determine the value N when booting the tablet computer. In this step, the tablet computer outputs a division number to each divided area. Further, a grid capable of identifying the divided area is displayed in the display screen area 220 in which the input can be made.
Thereafter, the tablet computer may receive the touch input for a grid corresponding to a location of a screen area having the icon 210 for the user input (FIG. 2D).
In addition, the tablet computer may receive directly input the division number corresponding to the location of the screen area having the icon 210 for the user input into the display screen area 220 in which input can be made.
In addition, the tablet computer may receive a tap number corresponding to a division number of the location of the screen area having the icon 210 for the user input in the display area 220 in which input can be made.
Thereafter, the tablet computer recognizes the division number of the location of the screen area having the icon 210 for the user input, and thereafter moves the area to the display screen area 220 in which the input can be made (FIG. 2E).
In addition, the tablet computer can recognize the division number of the location of the screen area having the icon 210 for the user input, and thereafter can move the icon of the area to the display screen area 220 in which the input can be made.
Thereafter, the tablet computer may receive the tab input for the icon included in the screen area having the icon 210 for the user input and moved to the display screen area 220 in which the input can be made (FIG. 2F).
In addition, the tablet computer may receive the tab input for the icon moved to the display screen area 220 in which the input can be made.
Thereafter, the tablet computer can execute a corresponding application program in a full screen in response to the tab touch input, and then can wait for a subsequent input (FIG. 2G).
FIG. 3 is a flowchart illustrating a process of operating a portable device according to an embodiment of the present disclosure.
Referring to FIG. 3, if the portable device receives a request for executing a pattern recognition function from a user (block 305), the portable device starts the pattern recognition function (block 310). The pattern recognition function can be turned on/off by the user. Thereafter, if the user performs a touch input on a specific pattern in the display screen of the portable device, the portable device can recognize the specific pattern.
Thereafter, if the portable device detects the specific pattern touch input from the user (block 315), the portable device displays a screen divided into (N+1) equal parts together with a grid and a corresponding number (block 320). Herein, the grid capable of identifying each divided area can be displayed in a divided touch area. The divided touch area represents a display screen area in which input can be made. Also, the divided touch area represents a divided area in which the portable terminal receives an input for selecting the specific divided area and a location of the divided touch area and a size of the divided touch area are not limited.
Thereafter, the portable device determines whether a first input of the user is detected in the divided touch area (block 325). The first input represents an input for indicating a screen area having an icon or item for a user input by the user among the (N+1) divided areas. If the first input of the user is detected in the divided touch area, the portable device analyzes the first input (block 330).
The first input may be an input for a grid corresponding to a location of a screen area having the icon or item for the user input, an input for a number assigned to a location of the screen area having the icon or item for the user input, and a tab input of which a number corresponds to the number assigned to the location of the screen area having the icon or item for the user input.
After analyzing the first input, the portable device moves an area indicated by the first input to the divided touch area (block 335). In some embodiments, the portable device may move only an icon of the area to the divided touch area.
Thereafter, the portable device determines whether there is a second input for an icon on the divided area moved to the display screen area in which the user input can be made by using a finger, that is, the divided area moved to the divided touch area, or for an icon moved to the divided touch area (block 340).
Thereafter, the portable device executes an application program for the icon in response to the second input (block 345).
The method described above in relation with FIG. 3 under of the present invention may be provided as one or more instructions in one or more software modules stored in the respective apparatus.
FIG. 4 is a flowchart illustrating a process of processing a first input in a portable device according to an embodiment of the present disclosure.
Referring to FIG. 4, if the first input is a tab input of which a number corresponds to a number assigned to a location of a screen area having an icon or item for a user input (block 405), the portable device recognizes the input tab number as a number for a divided area (block 410).
If the first input is an input for a grid corresponding to a location of the divided area, that is, the location of the screen area having the icon or item for the user input (block 415), the portable device recognizes the location of the input divided area as a number assigned to the divided area (block 420).
If the first input is an input for a number assigned to the screen area having, the icon or item for the user input (block 425), the portable device recognizes a number corresponding to the number input by the user by analyzing the touch input for the number (block 430), and recognizes the recognized number as a number assigned to the divided area (block 435).
The method described above in relation with FIG. 4 under of the present invention may be provided as one or more instructions in one or more software modules stored in the respective apparatus.
FIG. 5 is a block diagram of a portable device according, to an embodiment of the present disclosure.
Referring to FIG. 5, the portable device includes a modem 510, a controller 520, a storage unit 530, a touch input unit 535, a touch manager 540, and a display unit 545.
The modem 510 is a module for communicating with another device, and includes a radio processor, a baseband processor, and the like.

The storage unit 530 performs a function for controlling an overall operation of the portable device and a function for storing temporary data generated while performing the program.
The touch input unit 535 receives a touch input from the user, and provides data for the input to the controller 520 or the touch manner 540.
The display unit 545 displays output data of the controller 520 and the touch manager 540.
The touch manager 540 performs a pattern recognition function. The pattern recognition function may be turned on/off by the user. Thereafter, if the user performs a touch input on a specific pattern in the display screen of the portable device, the portable device can recognize the specific pattern.
Thereafter, upon detection of the specific pattern input from the user, the touch manager 540 displays a screen divided into (N+1) parts. In this situation, a grid capable of identifying the divided area can be displayed together with the grid and a division number in the divided touch area.
Thereafter, the touch manager 540 determines whether a first input is detected in the divided touch area. The first input represents an input for indicating a screen area having an icon or item for a user input among the (N+1) divided areas. If the first input is detected in the divided touch area, the portable device analyzes the first input. The division number may not be displayed in the divided touch area.
The first input may be an input for a grid corresponding to a location of a screen area having the icon or item for the user input, an input for a number assigned to a location of the screen area having the icon or item for the user input, and a tab input of which a number corresponds to the number assigned to the location of the screen area having the icon or item for the user input.
After analyzing the first input, the touch manager 540 moves an area indicated by the first input to the divided touch area. In some embodiments, the touch manager 540 can move only an icon of the area to the divided touch area.
Thereafter, the touch manager 540 determines whether there is a second input for an icon on the divided area moved to the display screen area in which the user input can be made by using the finger, that is, the divided area moved to the divided touch area, or for an icon moved to the divided touch area.
Thereafter, the touch manager 540 executes an application program for the icon in response to the second input.
If the first input is a tab input of which a number corresponds to a number assigned to a location of a screen area having an icon or item for a user input, the touch manager 540 recognizes the input tab number as a number for a divided area.
If the first input is an input for a grid corresponding to a location of the divided area, that is, the location of the screen area having the icon or item for the user input, the touch manager 540 recognizes the location of the input divided area as a number assigned to the divided area.
If the first input is an input for a number assigned to the screen area having the icon or item for the user input, the touch manager 540 recognizes a number corresponding to the number input by the user by analyzing the touch input for the number, and recognizes the recognized number as a number assigned to the divided area.
