FIG. 2 is a flowchart illustrating an input method according to an embodiment of the present invention.
Referring to FIG. 2, a terminal determines whether a selection UI display input signal is received in step 210. The selection UI display input signal is displayed in the display unit of the terminal and a user selects a specific coordinate on the display unit through the selection UI or performs at least one of operations which move an icon corresponding to the selected coordinate. For example, the selection UI display input signal is a drag signal received in the input unit of the terminal. The selection UI is displayed in the display unit of the terminal according to a direction of a drag based on the drag signal. As another example, the selection UI display input signal is received in the terminal by performing a button input in the input unit of the terminal or performing a drag input after previously setting a specific mode. As yet another example, a user of the terminal inputs the selection UI display input signal through a hold input after repeating two or more touches within a preset time.
In step 215, the terminal displays the selection UI based on a received selection UI display input signal in step 210. When the selection UI is displayed according to a drag input, a selection UI extended based on a direction of the drag input is displayed. When a touch input continues after the drag input, a size of the selection UI is extended in response to a touch input time, for example, a length of the selection UI is extended in the extended direction. Further, a speed at which the selection UI is extended is determined based on at least one of a touch pressure, a touch area and a speed of a drag input.
In step 220, the terminal determines whether a movement input signal is received. The movement input signal may include a drag input signal that is additionally received in the input unit. Further, the movement input signal may include a drag input that is performed after not touching during a preset time and then touching again.
When the movement input signal has been received in step 220, the terminal moves a selection UI corresponding to the movement input in step 225. The selection UI may be moved corresponding to the drag input, for example, a trailing end of the selection UI which is apart from the user's touch may be moved. Further, the terminal may change a length of the selection UI in order to move the selection UI corresponding to a movement input.
In step 230, the terminal determines whether a selection input signal is received. The selection input signal may include an input for releasing an input which is held in the input unit. The selection input signal may include a signal input through the button input unit of the terminal.
In step 235, the terminal selects an icon (e.g., a specific coordinate) displayed on the display unit based on the selection input signal received in step 230. A selection of the icon (e.g., the specific coordinate) may include selecting at least one of a plurality of icons (e.g., coordinates) located in an area overlapped with the selection UI. More specifically, the selection UI may include a selection area displayed inside or outside of the selection UI. When the selection input signal has been received, at least one of the icons (e.g., coordinates) which are in an area overlapped with the selection area may be selected.
In step 240, the terminal determines whether a re-input signal meeting a preset condition is received. More specifically, the re-input signal may include at least one of a touch input, a hold input and a drag input, which are input within a preset time after the selection input. For example, a corresponding icon through a selection input (e.g., release input) is selected in step 235, and a re-input signal is received in step 240. When the re-input signal has been received in the input unit within the preset time, the terminal proceeds to step 215, and a selection UI is displayed. More preferably, the selection UI is displayed corresponding to a size of the selection UI when a previous selection input has been received.

Referring to FIG. 3, the terminal receives a slide input signal in step 310. The slide input signal may include a drag input which moves while touching a part of the display unit of the terminal. The terminal may receive at least one of information about a direction, a speed and a touch area of the slide input through the slide input. The slide input may be substituted by two or more touches that are repeated within a constant area of an input unit, and the input unit may calculate a radius of an area on the display unit in which the touch is performed. A step of switching an input mode of the terminal before receiving the slide input may be added, and the terminal may determine whether a selection UI display input according to the added step is received.
In step 315, the terminal displays a selection UI based on the received input signal in step 310. The selection UI may be displayed in a transparent type on an icon displayed on the display unit. A display position of the selection UI may be determined based on the input received.
In step 320, the terminal receives a hold input signal. The hold input signal includes a signal generated by a touch applied to the input unit within a preset area and within a preset time.
In step 325, the terminal extends the selection UI based on at least one of the signal received in step 320 and the signal received in step 310. A direction of extending the selection UI may be determined based on a direction of the slide input received in step 310. The direction of extending the selection UI may be determined based on a direction of a semi-major radius of a touch area in which the touch input is received in step 310. The direction of extending the selection UI may be determined based on a direction of a semi-major radius of a touch area in the hold input received in step 320. Further, an extending speed of the selection UI may be determined based on at least one of signals received in step 310 and step 320. The extending speed of the selection UI may be determined based on at least one of a speed of the slide input received in step 310, a touch speed of a multi touch received in step 310, a touch area of the hold input signal received in step 320, and a pressure of the hold input signal received in step 320. In addition, the terminal may move the selection UI based on at least one of the signal received in step 320 and a signal received in step 310.
In step 330, the terminal determines whether an extending stop input signal is received. The extending stop input signal may include at least one of the drag input and the touch input within the preset time after a release input is performed. For example, when the drag input is performed, an expansion of the selection UI is stopped and the selection UI is moved based on a direction of the drag input.
In step 335, the terminal displays a selection UI according to a user's input. More specifically, when the release input as part of the extending stop input signal is performed, an operation of selecting at least one of the icons in an area, in which the selection UI is displayed, in the display unit may be performed.
