Hereinafter, a schematic configuration of a mobile terminal according to an embodiment of the present invention will be described. 1 is a diagram schematically illustrating an example of a configuration of a portable terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a configuration of a portable terminal according to an exemplary embodiment of the present invention may include a wireless communication unit 110, an audio processing unit 120, an input unit 130, a storage unit 140, a display unit 150, and a control unit ( 160).

The wireless communication unit 110 is responsible for a series of communication for wirelessly transmitting and receiving user data, for example, a message such as a message and a voice, to an external portable terminal. The wireless communication unit 110 includes a radio frequency (RF) transmitter for up-converting and amplifying a frequency of a signal to be transmitted, a low noise amplifying signal and a down-converting frequency of a received signal. down-converting). The modulated signal received from the controller 190 is converted into an intermediate frequency (IF) and then converted into a radio frequency (RF) signal and transmitted to the base station through an antenna (ANT, antenna). The signal is received through an antenna, and is sequentially converted to an intermediate frequency (IF) and a base band and provided to the controller 190.

The audio processor 120 reproduces an audio signal output from the controller 190 or transmits an audio signal such as a voice input from a microphone MIC to the controller 190. That is, the analog voice signal received from the microphone MIC is converted into a digital signal (PCM, Pulse code modulation) and transmitted to the controller 190. In addition, the digital signal PCM of the opposite voice coming from the control unit 190 is converted into an audible analog signal and serves to send to the speaker (SPK).

The input unit 130 includes a plurality of input keys and function keys for receiving numeric or character information and setting various functions. The function keys may include direction keys, side keys, shortcut keys, and the like, which are set to perform a specific function. In addition, the input unit 130 transmits a key signal input in relation to user setting and function control of the portable terminal to the controller 190.

The storage 140 stores an application program required for operating a function according to an embodiment of the present invention, and stores content to be downloaded and user data generated by a user.

The storage unit 140 may include a program area and a data area. The program area stores an operating system (OS) for booting the portable terminal, other option functions of the portable terminal, for example, an application program required for a music playback function, an image or video playback function, and the like. When activating each of the above functions according to a user's request, the respective functions are provided through corresponding application programs under the control of the controller 160. In addition, the storage 140 may temporarily store user data (music file, still image, video) generated during the execution of an application program according to a playback function such as a predetermined application (eg, music or video). May contain a (buffer).

The data area is an area in which user data according to the use of the mobile terminal is stored. For example, a music file, a video file, and the like may be stored.

The display unit 150 visually provides a menu of the portable terminal, user data input by the user, function setting information, and various information to the user. The display unit 150 may be formed of a liquid crystal display (LCD). In this case, the display unit 150 may include a control device for controlling the liquid crystal display, a video memory capable of storing image data, an element of the liquid crystal display, and the like. According to an embodiment of the present invention, when the display unit 150 is formed in the form of a touch screen, the display unit 150 may perform some or all of the functions of the input unit 130.

In more detail, the touch screen, which is the display unit 150 according to the exemplary embodiment, generates a voltage or current signal corresponding to the pressed position of the touch panel to input a command or graphic information designated by the user. The touch screen includes a touch panel, a liquid crystal panel, and a backlight independently.

The touch screen is a stack of a touch panel, a liquid crystal panel, and a backlight sequentially. The apparatus may further include a signal line for supplying a signal from the touch panel to the controller and a tape carrier package (TCP) connected to the lower substrate of the liquid crystal panel to apply an electrical signal to the liquid crystal panel driver.

The touch panel includes upper and lower substrates formed of ITO or polyethylene terephthalate (PET) film having an Indium-Tin-Oxide (ITO) electrode film, and an electrode pattern formed on the electrode film. And a spacer for maintaining a proper distance between the upper and lower substrates and bonding the upper and lower substrates.

Conductive X-axis patterns and Y-axis patterns are formed at the edges of the ITO electrode film, respectively, and the X-axis pattern and the Y-axis pattern are separated by an insulator. When the user presses the upper substrate with a finger or the like, the ITO electrode film on the upper substrate contacts the ITO electrode film on the lower substrate. Accordingly, by reading the voltage from the X-axis pattern and the Y-axis pattern, the coordinates of the pressed point are extracted and the controller ( 160).

The liquid crystal panel displays an image by controlling the light transmittance of liquid crystal cells injected between two glass substrates. Each of the liquid crystal cells adjusts the amount of light transmitted in response to the video signal, that is, the corresponding pixel signal.

The controller 160 controls the overall operation of the portable terminal and the signal flow between the internal blocks of the portable terminal. That is, the controller 160 controls the signal flow between the components of the wireless communication unit 110, the audio processing unit 120, the input unit 130, the storage unit 140, and the display unit 150.

The controller 160 performs each function of the mobile terminal according to an input signal (for example, a key input signal or a touch event for touching the touch screen) input from the input unit 130, and the current state and the user menu according to the performance of the function. Information such as the display unit 180 is displayed.

In particular, the controller 160 converts the PCM voice signal provided from the audio processor 120 through channel coding and interleaving and modulates the voice signal to the wireless communication unit 110 when processing a voice signal for a telephone call. It provides a voice signal provided from the wireless communication unit 110 as a PCM voice signal through demodulation, equalization, channel decoding and deinterleaving and sends it to the audio processor 120. . In order to perform this function, a modem and a codec may be included. The codec includes a data codec for processing packet data, an audio codec for processing an audio signal such as voice, and a video codec for processing a video signal.

Looking at the touch screen input method of the mobile terminal having the above-described configuration, when a touch event occurs, the display unit 150 according to an embodiment of the present invention transmits the coordinates of the touch event to the controller 160. That is, the touch screen senses a voltage or current signal corresponding to the pressed position (including one coordinate and a trace of the coordinates) and transmits the coordinates to the controller 160. Then, the controller 160 performs a function preset to the corresponding event according to the coordinates. In addition, the touch screen detects the time pressed and transmits the time to the controller 160. Then, the controller 160 performs a preset function for the event corresponding to the time. In addition, the controller 160 may perform other functions according to the position and time at which the touch screen is pressed. Examples of such touch events include long keys, short keys, and drags.

In more detail, a method for providing an interface using a touch screen according to an embodiment of the present invention will be described based on a portable terminal having the above configuration.

First, the data structure of a menu including an executable file used in an embodiment of the present invention will be briefly described. 2 is a diagram illustrating a tree structure of a menu having an executable file as a lowest depth according to an exemplary embodiment of the present invention.

Referring to FIG. 2, a data structure according to an embodiment of the present invention has three depths as shown. An example of such a data file is a music file, which has a number of albums per artist (singer, group, band) and a number of tracks per album. As described above, in the case of a music file, the artist may be classified into an artist at a first depth, an album of a corresponding artist at a second depth, and a track of the album at a third depth.

In this case, as shown in Fig. 2, the music file has a tree structure. The present invention is to quickly and intuitively execute the search and execution of a menu having such a tree structure.

Herein, a music file is described as an example, but the present invention is not limited thereto, and the menu of the mobile terminal device has such a tree structure, and the lowest depth of the tree structure is located in an executable file (for example, each track of the music file). I was thinking.

In addition, in the embodiment of the present invention, the tree structure of the data file is not limited to the case of three stages. For clarity of the gist of the present invention, the music file is described as an example of the data file having the tree structure of three stages. Let's do it.

Based on the above-described tree structure will be described a method for providing an interface using a touch screen according to an embodiment of the present invention. 3A to 3E are screen examples for explaining a method for providing an interface using a touch screen according to an exemplary embodiment of the present invention. In this case, the screen examples of FIGS. 3A to 3E show an interface for music reproduction on the touch screen of the display unit 150.

When the controller 150 detects an input signal for requesting music playback from the user, the controller 150 displays the album jacket of the music through the display unit 150 and plays the music through the speaker SPK of the audio processor 120. do. This music reproduction screen is shown in Fig. 3A.

In this case, when a touch event (first touch event) occurs in a predetermined region of the display unit 150, the controller 160 detects this and displays a screen as illustrated in FIG. 3B.

In this case, the touch event will be referred to as a "first touch event" for convenience of description. That is, a touch of a predetermined region of the touch screen (the display unit 150) by the user's action while playing music on the screen of FIG. 3A is referred to as a “first touch event”.

When the first touch event occurs, the controller 160 displays the control panel 300 to overlap with a predetermined area of the album jacket through the display unit 150. An example of such a screen is shown in FIG. 3B. In this case, the control panel 300 is preferably displayed by sliding. 3C is a diagram illustrating that the control panel 300 is displayed by sliding.

The control panel 300 is for searching for the track of the album and playing the track of the album. For this function, the controller 160 displays the control panel 300. That is, the control panel 300 is for searching for and executing an executable file.

At this time, the indicator panel 350 indicating the received signal strength (RSSI), the current time, the remaining battery level, and the like may also be displayed by sliding.

As shown in FIGS. 3B and 3C, the control panel 300 has a left icon 310 positioned on the left side of the control panel 300, and is spaced a predetermined distance from the left icon 310 in a right direction. The right direction icon 320 is displayed.

Also, the title 330 of the track currently being played is displayed between the left direction and the right direction icons 310 and 320 of the control panel 300. Here, when the track title 330 is displayed, the area where the track title 330 is displayed may be displayed as a search bar 340 instead of the track title 330. An example of such a screen is illustrated in FIG. 3D and will be described in more detail below.

In addition, the control panel 300 newly defines the touch sensing area. That is, the touch sensing area may be divided into an area where the control panel 300 is displayed and an area where it is not. In addition, different functions may be performed according to an area where a touch event occurs.

Preferably, the area in which the control panel is displayed is for searching and executing between executable files according to the touch, and the area in which the control panel is not displayed is for providing a search function at an upper depth of the executable file according to the touch.

Here, for convenience of description, when a touch event occurs in a region where the control panel 300 is displayed on the screen on which the control panel 300 is displayed, this is referred to as a “second touch event”. In addition, when a touch event occurs in an area where the control panel 300 is not displayed on the screen on which the control panel 300 is displayed, this is referred to as a “third touch event”.

Meanwhile, the second touch event may perform another function according to the area in which the touch event occurs and the touch input method.

The sensing area of the control panel 300 may be divided into a predetermined area in order to provide another function according to the generation area and method of such a touch event. The predetermined areas are divided by using icons to intuitively indicate that different functions can be provided according to the predetermined areas. The left direction icon 310 and the right direction icon 320 are displayed with these icons.

In more detail, the corresponding function according to the second touch event generating region and method will be described with reference to Table 1 below. Table 1 below is for explaining a corresponding function according to the second touch event according to an embodiment of the present invention. Here, a long key refers to a method in which a user presses a specific area of the touch screen for a predetermined time, and a short key refers to a method in which the user presses and releases a specific area of the touch screen in an instant. .

Touch area of the second touch event Touch input method Corresponding function One Left icon area Short Key Explore previous song 2 Left icon area Longkey Rewind 3 Right icon area Short Key Explore next song 4 Right icon area Longkey Forward forward 5 Track title area Short Key Pause 6 Track title area Longkey stop 7 Track title area Short key in paused state play

Referring to <Table 1> and FIGS. 3B and 3C, the left direction icon 310 supports rewinding and searching for a previous song of a music file, and the control panel 300 to intuitively indicate this point. It is shown on the left side of the.

In this case, when the user presses an area in which the left direction icon 310 is displayed with a short key, the controller 160 detects this and searches for a previous song (track) and then plays the searched track.

In addition, when the user presses the area where the left direction icon 310 is displayed for a predetermined time with a long key, the controller 160 detects this and displays the search bar 340 instead of the track title 330 on the control panel 300. In addition, it rewinds the currently playing track as long as the long key is pressed. In this case, it is preferable to display the remaining time 343 of the track playback through the search bar 340 and to display the position being searched, that is, the elapsed time 341.

The right direction icon 320 is displayed spaced apart from the left direction icon 310 in the right direction at a predetermined interval, and supports forwarding and searching for the next song.

In this case, when the user presses the area in which the right direction icon 320 is displayed with a short key, the controller 160 detects this and searches for the next track (track) and then plays the searched track.

In addition, when the user presses the long key for a predetermined time in the area where the right direction icon 320 is displayed, the controller 160 detects this and displays the search bar 340 instead of the track title 330 on the control panel 300. It also fast forwards the currently playing track by the time the long key is pressed. In this case, it is preferable to display the remaining time 343 of the track playback through the search bar 340 and to display the position being searched, that is, the elapsed time 341.

The search bar 340 described above disappears after performing a search function (rewind and forward), and instead, the track title 330 may be displayed.

In a state in which the track title 330 is displayed, when the user presses a short key on the area where the track title 330 is displayed, the controller 160 detects this and pauses playback of the track.

At this time, it is preferable to display the track title 330 by blinking to indicate pause.

In this pause state, when the user presses a short key on the area where the track title 330 is displayed, the controller 160 detects this and resumes playback of the track.

In addition, when the user presses a long key on the area where the track title 330 is displayed while the track title 330 is displayed, the controller 160 detects this and stops playing the track.

The second touch event is an event occurring in an area where the control panel is displayed, whereas the third touch event is an event that occurs when a user touches an area in which the control panel 300 is not displayed while the control panel is displayed. . When such a third touch event occurs, the controller 160 detects this, searches for the previous album or the next album, and plays any track of the corresponding album.

That is, the third touch event provides a function for searching between albums which are higher depths of the executable file.

At this time, if the third touch event is an input of dragging from left to right, the previous album is searched. If the third touch event is an input of dragging from right to left, the next album is searched.

Referring to FIG. 3E in more detail, when the user drags from the right to the left direction, the controller 160 detects this and displays the next album as if it slides, and plays any track of the corresponding album. As shown in the figure, dragging from the right side to the left side slides and displays the next album as if turning the bookshelf. That is, as if turning the bookshelf, the search is performed after the index at the same depth (second depth, album in the embodiment of the present invention). This search method is similar to a method of turning over a bookshelf so that a user can intuitively search. That is, the third touch event searches for the front or the back of the index through an action (left or right dragging) that looks like turning the user's bookshelf.

As described above, when the second and third touch events occur while displaying the control panel for performing a specific function according to the first touch event, the second and third touch events are generated. The function may be pre-mapped according to the generated area and the touch input method.

This method may retrieve the upper depth of the data structure (e.g., album), the lower depth (e.g., track) of the data structure, and in the case of the lower depth, which is an executable file, additional functions according to the execution ( For example, in the case of a music file, all of the forward, backward, pause, stop, and play) can be intuitively performed.

In the above, the function according to the interface (particularly, the control panel) and each touch event (particularly, the second and third touch events) associated with the same according to an embodiment of the present invention has been described. An interface providing method according to an exemplary embodiment of the present invention will be described with reference to a flowchart based on the above-described interface for reproducing music. 4 is a flowchart illustrating a method of providing an interface using a touch screen of a mobile terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 4, the controller 160 is performing the standby mode in step S401. When the user inputs a key for requesting a music playing function during the standby mode, the controller 160 detects this in step S403 and displays an album list in step S405.

Here, the entry into the step of displaying the album list may be sequentially entered through a menu, and a short cut function such as a hot key may be used.

On the other hand, when the user inputs a key for requesting another function, the controller 160 detects this in step S403 and performs the corresponding function in step S407.

If the user selects any one album in the state of displaying the album list in step S411, the controller 160 detects it in step S409 and plays music of the track included in the album in step S413. This music reproduction screen is shown in Fig. 3A.

As shown in FIG. 3A, the controller 160 displays the album jacket of the track through the display unit 150, and at the same time, the controller 160 plays music of the track. At this time, the playback order may be played from the first track of the corresponding album or may be played in any order. In addition, the user can set the playback order as necessary.

During the music playback, when a user encounters a first touch event of touching the touch screen, which is the display unit 150, the controller 160 detects it in step S415, and the control panel 300 through the display unit 150 in step S415. ). The screen on which the control panel 300 is displayed is illustrated in FIG. 3B. As shown in the drawing, the control panel 300 overlaps a predetermined area of the album jacket while displaying the album jacket. In addition, as shown in FIG. 3C, the control panel 300 may be displayed by gradually sliding.

When the control panel 300 slides to complete display, the controller 160 detects whether a predetermined time has elapsed since the display of the control panel 300 is completed in step S419. Preferably, the controller 160 detects whether a time of 3 seconds has elapsed.

As a result of the detection of step S419, when a predetermined time elapses, the controller 150 proceeds to step S421 to cause the control panel 300 to disappear from the display unit 150. Here, it is preferable that the control panel 300 slides away. Then, the controller 150 proceeds to step S413 to play the music of the track.

As a result of the detection in step S419, if the predetermined time has not elapsed, the controller 150 detects whether a second touch event occurs in step S423.

If the controller 150 detects the occurrence of the second touch event in operation S423, the controller 160 performs a function according to the second touch event in operation S425. The function according to the second touch event is as described with reference to FIGS. 3A to 3D.

If the second touch event does not occur in step S423, the controller 160 detects whether a third touch event occurs in step S427, and performs a function according to the third touch event in step S429. Performing a function according to the third touch event is as described with reference to FIG. 3E.

If the third touch event does not occur as a result of the sensing in step S427, the controller proceeds to step S419 to detect whether a predetermined time has elapsed after the display of the control panel is completed.

As described above, the embodiment of the present invention provides an interface for controlling the execution file of the lowest depth of the tree structure by displaying the control panel on a predetermined area of the touch screen. In addition, the area where the control panel is not displayed is provided as an interface for controlling the upper depth of the executable file. Therefore, the present invention can control all the depths of the tree structure of the menu using one touch screen.

While the present invention has been described using some preferred embodiments, these embodiments are illustrative and not restrictive.

That is, in the exemplary embodiment of the present invention, the menu has a tree structure, and the lowest depth is described as an example of a music file having an executable file.
