2 is a flowchart illustrating a procedure for providing a user interface of a portable terminal according to an embodiment of the present invention.

Referring to FIG. 2, the procedure for providing a user interface according to the present embodiment starts with the controller 130 displaying an operation screen in step 211. That is, the controller 130 activates the touch screen 120 and displays an operation screen through the touch screen 120. At this time, the control unit 130 displays an operation screen corresponding to a menu or application currently being executed.

Next, when a touch is generated on the touch screen 120, the controller 130 detects it in step 213 and detects a touch area corresponding to the touch in step 215. At this time, the controller 130 further detects the touch position. For example, the controller 130 may detect a size of an area where a touch is sensed on the touch screen 120 as a touch area, and detect any one of a plurality of coordinates of the corresponding area as a touch position. In step 217, the controller 130 compares the touch area with a preset area threshold. Here, the area threshold may be a single value, and may be made of values corresponding to a certain range. In this case, the controller 130 may compare the overall size of the touch area with the area threshold, and may compare the length corresponding to a specific direction in the touch area with the area threshold. That is, the controller 130 determines whether the touch area is equal to or greater than the area threshold.

Next, if it is determined in step 217 that the touch area is equal to or greater than the area threshold, the controller 130 recognizes the touch as a palm touch in step 219 and performs a palm touch mode for executing a function corresponding to the palm touch. In this case, if the touch area is greater than or equal to the upper limit among values corresponding to the area threshold, the controller 130 may perform the palm touch mode. Here, the controller 130 further classifies a touch operation according to at least one of whether the palm touch is moved, a movement distance, a movement direction, or a holding time, and performs a function corresponding thereto. The procedure of performing the palm touch by the control unit 130 will be described in more detail as follows.

FIG. 3 is a flowchart illustrating a procedure of performing a palm touch mode in FIG. 2. And FIGS. 4 to 7 are exemplary diagrams for exemplarily explaining a procedure of performing a palm touch mode in FIG. 2.

Referring to FIG. 3, the controller 130 determines whether there is movement in the palm touch in step 311. In this case, the controller 130 may determine whether the palm touch is moved by checking whether the palm touch deviates from the area corresponding to the preset holding range from the touch position.

Next, if it is determined that there is movement in the palm touch in step 311, the controller 130 tracks the movement direction of the palm touch in step 313 and detects the movement distance. In this case, the movement of the palm touch includes a drag, a sweep, and a twist of the palm touch. In step 315, the controller 130 compares the moving distance with a preset distance threshold. Here, the distance threshold may be a single value, and may be formed of a plurality of values divided at regular intervals. Also, the distance threshold may be set corresponding to a specific direction. In this case, the controller 130 may compare the moving distance with the distance threshold, and may associate the moving distance with the moving direction and compare with the distance threshold. That is, the controller 130 determines whether the moving distance is equal to or greater than the distance threshold.

Next, if it is determined in step 315 that the moving distance is equal to or greater than the distance threshold, the controller 130 determines a touch operation of the palm touch in step 321 and performs a function corresponding thereto. In this case, if the moving distance is greater than or equal to the lower limit of the values corresponding to the distance threshold, the controller 130 compares the moving distance with each value corresponding to the distance threshold. Further, the controller 130 determines a touch operation of the palm touch by detecting a value corresponding to the moving distance, and performs a function corresponding thereto. In this case, in response to the release of the palm touch on the touch screen 120, the controller 130 may determine a touch operation and perform a function corresponding thereto. After that, the control unit 130 returns to FIG. 2. Meanwhile, if it is determined in step 315 that the moving distance is less than the distance threshold, the controller 130 returns to FIG. 2.

For example, as shown in (a) of FIG. 4, when the hand blade of the user of the mobile terminal 100 passes from left to right of the touch screen 120 while displaying the operation screen, the controller 130 moves the palm touch. Can be detected. In this case, the controller 130 may track the moving direction of the palm touch and detect the moving distance. In addition, when the moving distance is greater than or equal to the distance threshold, the controller 130 may capture an operation screen as an image as shown in FIG. 4B.

Alternatively, as shown in (a) of FIG. 5, when the hand blade of the user of the mobile terminal 100 passes from the top to the bottom of the touch screen 120 during the operation screen display, the controller 130 detects the movement of the palm touch. I can. In this case, the controller 130 may track the moving direction of the palm touch and detect the moving distance. In addition, when the moving distance is greater than or equal to the distance threshold, the controller 130 may switch from the operation screen to another screen and display it as shown in FIG. 5B. In this case, the other screen may be preset by the controller 130, and may be, for example, a home screen. Here, the controller 130 may terminate the currently executed menu or application. Alternatively, the controller 130 may display the home screen without terminating the currently running menu or application.

Alternatively, as shown in (a) of FIG. 6, when the palm of the user of the portable terminal 100 is twisted on the touch screen 120 during the operation screen display, the controller 130 may detect the movement of the palm touch. In this case, the controller 130 may detect the movement of the palm touch by detecting a change in the touch position of the palm touch. Here, the controller 130 may detect a movement of the palm touch by detecting changes in coordinates arranged at the boundary of the area corresponding to the palm touch. Alternatively, the controller 130 may detect a movement of the palm touch by detecting a change in a direction of a major axis among axes connecting coordinates arranged at a boundary portion of an area corresponding to the palm touch. In addition, the controller 130 may track the movement direction of the palm touch and detect the movement distance. In addition, when the moving distance is greater than or equal to the distance threshold, the controller 130 may set a lock on the touch screen 120 as shown in FIG. 6B. In this case, the controller 130 may output an audio signal for notifying the lock of the touch screen 120 through the audio processing unit 150.

On the other hand, if it is determined in step 311 that there is no movement of the palm touch, the controller 130 detects the holding time of the palm touch in step 317. That is, if the palm touch does not deviate from the region corresponding to the holding range, the controller 130 may determine that the palm touch is maintained without movement. In step 319, the control unit 130 compares the holding time with a preset time threshold. Here, the time threshold may be a single value, and may consist of a plurality of values divided at regular intervals. That is, the control unit 130 determines whether the holding time is equal to or greater than a time threshold.

Next, if it is determined in step 319 that the holding time is equal to or greater than the time threshold, the controller 130 determines a touch operation of the palm touch in step 321 and performs a function corresponding thereto. At this time, if the holding time is greater than or equal to the lower limit of the values corresponding to the time threshold, the controller 130 compares the holding time with each value corresponding to the time threshold. In addition, the controller 130 determines a touch operation of the palm touch by detecting a value corresponding to the holding time, and performs a function corresponding thereto. In this case, in response to the release of the palm touch on the touch screen 120, the controller 130 may determine a touch operation and perform a function corresponding thereto. After that, the control unit 130 returns to FIG. 2. On the other hand, if it is determined in step 319 that the holding time is less than the time threshold, the controller 130 returns to FIG. 2.

For example, the controller 130 may display an operation screen as shown in FIG. 7A. In this case, the controller 130 may perform a video call or digital broadcast reception to reproduce at least one of an image or an audio. And, as shown in (b) of FIG. 7, when the palm of the user of the portable terminal 100 touches the touch screen 120 while the operation screen is displayed, the controller 130 may detect the maintenance of the palm touch. In this case, the control unit 130 may detect the holding time of the palm touch. In addition, when the retention time is greater than or equal to the time threshold, the controller 130 may stop playing the video or audio in response to the operation screen. In addition, as shown in (b) of FIG. 7, when the user's palm of the mobile terminal 100 is released from the touch screen 120 in a state in which video or audio playback is stopped, the controller 130 As shown in a), video or audio playback can be performed.

Alternatively, the controller 130 may display an operation screen as shown in FIG. 7A. At this time, the controller 130 may stop playing at least one of an image or an audio. Here, the operation screen may be a still screen of an image. And, as shown in (b) of FIG. 7, when the palm of the user of the mobile terminal 100 is in contact with the touch screen 120 while the operation screen is displayed, the controller !30 may detect the maintenance of the palm touch. In this case, the control unit 130 may detect the holding time of the palm touch. In addition, when the retention time is greater than or equal to the time threshold, the controller 130 may reproduce video or audio in response to the operation screen.

Meanwhile, if it is determined in step 217 that the touch area is less than the area threshold, the controller 130 recognizes the touch as a finger touch in step 221 and performs a finger touch mode for executing a function corresponding to the finger touch. In this case, if the touch area is less than the lower limit among values corresponding to the area threshold, the controller 130 may perform the finger touch mode. Here, the controller 130 further classifies a touch operation according to at least one of whether the finger touch is moved, a moving distance, a moving direction, or a holding time, and performs a function corresponding thereto. The procedure for performing such a finger touch will be described in more detail as follows.

8 is a flowchart illustrating a procedure of performing a finger touch mode in FIG. 2. And FIGS. 9 and 10 are exemplary diagrams for exemplarily explaining a procedure of performing a finger touch mode in FIG. 2.

Referring to FIG. 8, in step 811, the controller 130 determines whether there is movement in the finger touch. In this case, the controller 130 may determine whether the finger touch is moved by checking whether the finger touch deviates from an area corresponding to a preset holding range from the touch position.

Next, if it is determined in step 811 that there is a movement in the finger touch, the controller 130 tracks the movement direction of the finger touch in step 813 and detects the movement distance. In this case, the movement of the finger touch includes dragging, sweeping, and twisting of the finger touch. In step 815, the controller 130 compares the moving distance with a preset distance threshold. Here, the distance threshold may be a single value, and may be formed of a plurality of values divided at regular intervals. Also, the distance threshold may be set corresponding to a specific direction. In this case, the controller 130 may compare the moving distance with the distance threshold, and may associate the moving distance with the moving direction and compare with the distance threshold. That is, the controller 130 determines whether the moving distance is equal to or greater than the distance threshold.

Next, if it is determined in step 815 that the moving distance is greater than or equal to the distance threshold, the controller 130 determines whether the touch area of the finger touch is changed in step 817. In step 823, the controller 130 determines a touch operation according to whether the touch area of the finger touch is changed and performs a function corresponding thereto. In this case, if the moving distance is greater than or equal to the lower limit of the values corresponding to the distance threshold, the controller 130 compares the moving distance with each value corresponding to the distance threshold. Further, the controller 130 determines a touch operation of the finger touch by detecting a value corresponding to the moving distance, and performs a function corresponding thereto. In this case, in response to the release of the finger touch on the touch screen 120, the controller 130 may determine a touch operation and perform a function corresponding thereto. After that, the control unit 130 returns to FIG. 2. Meanwhile, if it is determined in step 815 that the moving distance is less than the distance threshold, the controller 130 returns to FIG. 2.

For example, as shown in (a) of FIG. 9, when the user's finger of the mobile terminal 100 is twisted on the touch screen 120 during the operation screen display, the controller 130 can detect the movement of the finger touch. have. In this case, the controller 130 may detect a change in the touch position of the finger touch to detect the movement of the palm touch. Here, the controller 130 may detect a movement of the finger touch by detecting changes in coordinates arranged at the boundary of the area corresponding to the finger touch. Alternatively, the controller 130 may detect a movement of a finger touch by detecting a change in a direction of a major axis among axes connecting coordinates arranged at a boundary portion of an area corresponding to the finger touch. In addition, the control unit 130 may track the moving direction of the finger touch and detect the moving distance. In addition, if the moving distance is greater than or equal to the distance threshold, the controller 130 may rotate the operation screen as shown in FIG. 9B.

Alternatively, as shown in (a) of FIG. 10, when the user's finger of the mobile terminal 100 is dragged from the edge of the corner of the touch screen 120 to the inside during the operation screen display, the controller 130 May detect the movement of the finger touch. In this case, the controller 130 may track the moving direction of the finger touch and detect the moving distance. In addition, when the moving distance is greater than or equal to the distance threshold, the controller 130 may express an effect of folding a corresponding corner on the operation screen as shown in FIG. 10B. Thereafter, as shown in (c) of FIG. 10, when the user's finger of the mobile terminal 100 is maintained on the touch screen 120, the controller 130 determines whether the touch area corresponding to the finger touch is changed. can do. In addition, if it is determined that the touch area has changed, the controller 130 may process a bookmark on the operation screen as shown in FIG. 10D. That is, the controller 130 may record the location of the motion screen by adding it to the favorites list.

On the other hand, if it is determined in step 811 that there is no movement of the finger touch, the controller 130 detects the holding time of the finger touch in step 819. That is, if the finger touch does not deviate from the region corresponding to the holding range, the controller 130 may determine that the finger touch is maintained without movement. In addition, the control unit 130 compares the holding time with a preset time threshold in step 821. Here, the time threshold may be a single value, and may consist of a plurality of values divided at regular intervals. That is, the control unit 130 determines whether the holding time is equal to or greater than a time threshold.

Next, if it is determined in step 821 that the holding time is equal to or greater than the time threshold, the controller 130 determines a touch operation of the finger touch in step 823 and performs a function corresponding thereto. At this time, if the holding time is greater than or equal to the lower limit of the values corresponding to the time threshold, the controller 130 compares the holding time with each value corresponding to the time threshold. Further, the controller 130 determines a touch operation of the finger touch by detecting a value corresponding to the holding time and performs a function corresponding thereto. In this case, in response to the release of the finger touch on the touch screen 120, the controller 130 may determine a touch operation and perform a function corresponding thereto. After that, the control unit 130 returns to FIG. 2. On the other hand, if it is determined in step 821 that the holding time is less than the time threshold, the controller 130 returns to FIG. 2.

Meanwhile, in the above-described embodiment, it is described that the portable terminal is divided into palm touch and finger touch according to the touch area, but the present invention is not limited thereto. That is, as a plurality of area thresholds are set in the portable terminal, the portable terminal can classify the touch area according to various reference ranges using the area thresholds.
