An embodiment of the present disclosure is not limited thereto, and the menu display and the media player function may be selected by dragging in the horizontal direction, and the control value may be set by the drag input in the vertical direction.

The status bar 120 includes a previous file button 121 for selecting a previous file of the currently played file, a playback length display unit 122 scrolling the playback time of the currently played media file, and a currently playing file. A play time display unit 123 indicating a play time of the media file, a file name display unit 124 for displaying information such as a song title, singer, composer, etc. of the currently playing file, and a remaining play time indicating the remaining play time of the media file currently being played. A time display section 125, and a next file button 126 for selecting the next file of the media file currently being played.

While the media file selected by the user is playing, the play length display unit 122 may be displayed as a scroll bar in proportion to the play time, and the play length display unit 122 may have a length from left to right in proportion to the play time. Or right to left). The play time display unit 123 is located at one end of the play length display unit 122 and displays the time played by the media file in hours, minutes, or seconds.

The user may move the playback position of the media file by dragging one end of the play length display unit 122 to search for the media file currently being played. For example, when the user drags one end of the play length display unit 122 in the direction in which the play length display unit 122 extends, the media file currently being played may be moved forward in proportion to the dragged length or the dragging speed. In addition, when the user drags one end of the play length display unit 122 in a direction opposite to the direction in which the play length display unit 122 extends, the media file currently being played may be reversely moved in proportion to the dragged length or the dragging speed.

When the user wants to play the previous media file of the currently playing media file, the user touches the previous file button to select the previous media file. When the user wants to play the next media file, the user touches the next file button 126 to display the next media file. Is selected. When the user selects the previous file or the next file, the previous or next file is selected according to the number of touches. For example, if the user touches the previous file button twice, the second previous file of the currently playing file is selected, and if the next file button 126 is touched three times, the third and subsequent files of the currently playing media file are selected. do.

The first control area 310 is an area for controlling the media player, and includes a first control area 312 for controlling a media file to be played, a function display unit 311 for selecting a function of the media player, and playback of a media file. And a play / pause button 313 for pausing or stopping playback.

The function display unit 311 includes a function icon indicating a function of the current media player and a menu 311-2 for selecting a function of the media player.

The user may touch the menu 311-2 to select a function of the media player. When the user touches the menu 311-2, the first selection area 400 of FIG. 2 is displayed on an arbitrary area of the touch screen 110, and the selection area is one of a list type, a scroll type, and an icon type. It is expressed as

For example, as shown in FIG. 2, when the user touches the menu 311-2, in the first selection area 400, a playback speed adjustment button 401, a search button 403, and a brightness adjustment button 404 are displayed. -2), menu 311-2 and sound control button 402 are displayed in the form of an icon. When the user touches the menu 311-2 of the first selection area 400, the first selection area 400 disappears and the previous function display 311 may be displayed again.

The function window 312-1 is an icon representing the shape of the function of the media player selected by the user. When the user changes the function of the media player through the menu 311-2, the changed icon is displayed in the function window 312-1. .

For example, when the search function 403 is selected, the function window 312-1 displays 'SEEK', an icon of a function currently performed by the media player, as shown in FIG. 1 while the media file is being played.

The first control area 312 includes a function window 312-1 in which an icon representing a search function, which is the current function of the media player, is displayed, a forward key 312-2 for searching a media file currently being played, and a fast forward key 312. -3), reverse key 312-4, fast reverse key 312-5.

The user can change the function window 312-1 of the first control area 312 by the forward key 312-2, the fast forward key 312-3, the reverse key 312-4, or the fast reverse key 312-5. You can navigate to the media file that is currently playing.

When the user drags the function window 312-1 to the forward key 312-2, the media file is searched at the first search speed (for example, 1x speed), and the function window 312-1 is moved to the fast forward key. Drag to search for media files at a second search speed (e.g., 3x).

When the user drags the function window 312-1 to the reverse key 312-4, the media file is searched at the third search speed (for example, -1 times speed), and the function window 312-1 is fast reversed. Dragging to search for media files at the fourth search speed (e.g. -2x).

When the user drags an arbitrary area of the first control area 312, a control value using a drag direction, a drag distance, or a drag time based on the initial touch point (for example, the function window 312-1). Is calculated.

According to the calculated control value, the selected function of the media player is controlled. The control value is obtained by adding a change amount to a current value (for example, current volume, current speed, current brightness, etc.) that is a control value of the function of the currently selected media player. Value.

The control value is calculated by the following equation.

Based on the user's initial touch point, the reverse direction (eg, left) means a decrease (-) of the change amount, and the forward direction (eg right) means an increase (+) of the change amount.

The amount of change dx of the function to be adjusted by the media player is determined according to at least one of the dragged distance and the drag time. The amount of change increases or decreases in proportion to or inversely proportional to at least one of the drag distance and the drag time.

The change amount dx is a drag distance corresponding to a touch input or a weight a over time to a reference change value g arbitrarily set according to a characteristic of a function (volume, double speed, brightness, etc.) to be adjusted according to the selected function. Calculated by multiplication.

For example, the reference change value g1 according to the drag distance is set to increase (or decrease) by 1 every 5 mm (or increase (or decrease) by 1 every 10 mm), and the weight a1 of the volume is 1 and doubles the speed. The weight a2 of may be set to 0.1.

The change amount is calculated by the following equation.

In addition, the touch time, which is the time for which the touch is maintained in the distance (state where the drag stops and maintains the touch), serves as a trigger for determining the start of the control value calculation.

The trigger unit time may be a unit time at which a function of a selected media player is performed or updated, or may be a unit time at which a control value of a function of a selected media play is calculated or updated.

The trigger unit time can be set to any value of 1 to n (n is an integer), and the smaller the trigger unit time, the faster the control value is calculated. For example, when the trigger unit time is 1, the control value is calculated every 1 second. When the trigger unit time is 0.5, the control value is calculated every 0.5 seconds.

For example, when the user touches the sound control button 402 to adjust the playback sound, the function window 312-1 of the first control area 312 is dragged to set the reference change value per hour, and the dragged It is assumed that the touch unit time is selected at the position to set the trigger unit time.

Specifically, the weight a1 of the drag distance unit is 1, the reference change value g1 according to the drag distance is 1 volume / 5 mm, and the function change amount 312-1 is dragged to the right to increase the unit change amount of the playback sound. It describes as being (+).

When the drag distance is 5 mm and the touch time at the dragged position is 0.5 second, the trigger unit time is 0.5 seconds, and the amount of change of the reproduced sound volume dx per trigger unit time is 1. When the current sound level Xn is 10, the change amount dx reproduction sound control value over time is shown in Table 1 below.

In addition, a case in which the user adjusts the playback sound according to the drag distance will be described below. The method of setting the reference change value and the trigger unit time per hour is as described above. Suppose the user drags 5mm for the first 1.5 seconds and then 10mm for 1.5 seconds.

Specifically, the weight a of the drag distance unit is 1, the reference change value g1 according to the drag distance is 1 volume / 5 mm, the reference change value g2 is 2 volumes / 10 mm, and the function window 312-1 Since this dragged to the right, the amount of change in the sound unit is explained as being increased (+).

Since the drag distance is 5mm for the first 1.5 seconds, the volume change amount (dx) is 1, and the drag distance is 10mm for 1.5 seconds, so the change amount (dx) is 2. When the trigger unit time is 0.5 seconds and the current sound volume Xn is 10, the change amount dx and the reproduction sound control value according to the drag distance are shown in Table 2 below.

When the user touches the playback control button 401, the navigation button 403, or the brightness control button 404 other than the sound control button 402 and controls the media player, the same method as the above-described sound control method is omitted.

The second control area 320 designates a file list button 321 for displaying a media file list, a sound control button 402, a bookmark 323 for displaying a specific location of a media file, and a specific section of a media file. An interval repetition button 324 for repeatedly playing, and an environment setting button 325 for setting the environment of the media player are included.

The sound control button 402 is a button for adjusting the playback volume of the media player, and increases or decreases the playback volume in proportion to the distance at which the user drags the sound control button 402. The sound control button 402 is linked with a function of adjusting the volume by the user selecting the sound control button 402 of the first selection area 400. Since the adjustment method of the sound control button 402 is the same as the adjustment of the first control region 312 described above, it will be omitted.

The third control area 330 includes a brightness control button 404-1 and increases or decreases the screen brightness of the information device 100 in proportion to the distance at which the user drags the brightness control button 404-1. . The brightness control button 404-1 is linked with a function of adjusting the brightness by the user selecting the brightness control button 404-2 of the first selection area 400.
