Abstract

A method for scrolling a list of a mobile terminal is provided to minimize inconvenience that users should continuously manipulate a key to manually scroll a list. When a user manipulates a key input unit to view call particulars or a contents list(S11), a controller receives a list display request(S12). The controller displays a corresponding list on a screen of a display unit(S13). When a key input is received by key manipulation of a user(S14), the controller checks whether the received key input is an automatic scroll request key(S15). When the automatic scroll request key is inputted by the user, the controller scrolls a list displayed on the display unit(S16). The controller continuously performs scrolling until a key input is received from the user(S17). When a certain key is inputted by the user, the controller checks whether the inputted key is a configuration key(S18). If the inputted key is not the configuration key nor a direction control key, the controller stops automatic scrolling(S20). The controller waits for a key input(S21). When a key is inputted by the user, the controller checks whether the inputted key is the configuration key(S22). When the inputted key is the confirmation key, the controller executes an item on which a curser is currently positioned(S23).

The control key according to the embodiment of the present invention includes a direction control key 162 and confirmation key 164.

The direction control key 162 is used to start scrolling the list or to change the scrolling direction. In the present invention, an example of using a volume control key (a side key generally used for volume control) as the direction control key 162 is shown. In the case of the volume control key, '▽' key used to decrease the volume is used as the down scroll key, and '△' key used to increase the volume is used as the up scroll key. However, the present invention is not limited thereto, and it is also possible to use an up key ↑ and a down key ↓ among direction keys (not shown) which can be operated in four directions.

In addition, when the list is scrolled left and right, the left key (←) and the right key (→) among the four direction keys can be used, or the '*' and '#' keys can be used. have. In addition, it is also possible to implement and use the direction control key 162 according to the present invention.

The confirm key 164 is used to execute the item where the cursor is located.

The display unit 150 displays image data output from the camera module 180 on the screen. Herein, the liquid crystal display (LCD) may be applied to the display unit 150. In this case, the display unit 150 may include an LCD controller, a memory capable of storing data, and an LCD display device.

The controller 190 performs an overall control operation of the portable terminal 100. In addition, when the list is displayed on the display unit 150 at the request of the user, the controller 190 scrolls and displays items of the list in a predetermined direction based on a key input from the user.

Next, the list scrolling method of the portable terminal 100 according to the present invention will be described in detail with reference to the following embodiments. The configuration of the above-described portable terminal will also be clearer from the following description of the list scrolling method.

2 is a flowchart illustrating a list scrolling method according to an embodiment of the present invention. 3A and 3B are diagrams illustrating a list display screen according to an embodiment of the present invention.

The list searching method according to the present invention will be described with reference to FIGS. 1 to 3B. When the user manipulates the key input unit 160 to view the call history or the content list in the mobile terminal 100 which is in the standby state in step S11, a list display request is received by the controller 190 in step S12.

When the list display request is received, the controller 190 displays a corresponding list on the screen of the display unit 150 as shown in FIG. 3A. 3A illustrates a list display screen in which sound source content (eg, MP3 content) is displayed as items of a list. However, it is not limited thereto.

At this time, the controller 190 distinguishes one item among a plurality of items constituting the list, for example, an item located at the top. In the present invention, a cursor is positioned on a specific item in a state where the specific item is distinguished. The cursor according to the present invention changes and displays a background color and a text color of a corresponding item so that a specific item is distinguished from a plurality of items. However, the present invention is not limited thereto, and the selected item may be flickered, or the item may be displayed by scrolling the item horizontally.

Meanwhile, in the present embodiment, when the list is displayed, the cursor is positioned on the item located at the top of the items displayed on the screen. However, the present invention is not limited thereto, and various applications are possible, such as displaying a cursor on an item selected by a user in a previous list display process.

When a list is displayed on the display unit 150 of the portable terminal 100 and a cursor is displayed on a specific item, a process of receiving a key input by a user's key manipulation is performed in step S14.

When the key input is received, in step S15, the controller 190 determines whether the received key input is an automatic scroll request key.

In the related art, a method of scrolling by moving a cursor using only an up-down key is mainly used. However, the present invention discloses a method of automatically moving a cursor and scrolling items according to the number of key inputs or key combinations.

In this embodiment, a method of requesting automatic scrolling through a continuous key input is used. That is, when the user inputs the '▽' key twice quickly in a volume control key (for example, double click), the controller 190 recognizes this as an automatic scroll request.

However, the present invention is not limited thereto, and when the direction control key 162 is continuously input in the same direction more than a certain number of times (for example, five times), various applications are possible, such as recognizing that an automatic scroll request is input in the corresponding direction.

As another example, a method of requesting automatic scrolling by simultaneously inputting two different keys may be used. That is, when the user inputs a predetermined key (for example, the '*' key) while pressing the '▽' key, the controller 190 recognizes this as a downward automatic scrolling request. Similarly, when the '*' key is pressed while the '△' key is pressed, the controller 190 recognizes this as an upward automatic scrolling request.

In addition, various methods may be used, such as inputting a combination of a plurality of keys in a certain order for an automatic scroll request, or inputting a specific key longer than a predetermined time.

On the other hand, if the key input by the user is not the automatic scroll request key, the controller 190 enters the process S151 and performs a command corresponding to the input key.

However, if an automatic scroll request is input from the user in step S15, the controller 190 scrolls the list displayed on the display unit 150 in step S16. Here, the speed at which the list is scrolled is preset by the user and may be changed. However, the present invention is not limited thereto, and various applications are possible, such as calculating and using an appropriate speed according to the total number of items included in the list.

In operation S17, the controller 190 continuously scrolls until a key input is received from the user. Thus, when the user inputs a predetermined key, the controller 190 determines whether the input key is the confirmation key 164 in step S18. If the input key is the confirmation key 164, the controller 190 proceeds to step S23 to execute the item where the current cursor is located. For example, when the confirmation key 164 is input in the state as shown in FIG. 3B, the controller 190 plays the content of 'Take It All' where the cursor is located by using the corresponding player.

However, if the key input in step S17 is not the confirmation key 164, in step S19, the controller 190 determines whether the input key is the direction control key 162 indicating the opposite direction. In this embodiment, an example of requesting automatic scrolling using the '▽' key among the volume control keys is shown. Therefore, in order to change the scroll direction, the user uses the '△' key indicating the opposite direction. However, the present invention is not limited thereto, and the direction change key may be separately set and used.

When the key input in step S17 is the direction control key 162 indicating the opposite direction, the controller 190 enters the process S191, switches the scroll direction to the opposite direction, and repeats the processes S17 to S19.

Meanwhile, if the key input in step S17 is not the confirmation key 164 or the direction control key 162 indicating the opposite direction, the controller 190 stops the automatic scrolling that is being performed in step S20.

Subsequently, in step S21, the controller 190 waits for a key input.

When a key is input from the user, the controller 190 determines whether the input key is the confirmation key 164 in step S22.

If it is not the confirmation key 164, the controller 190 returns to step S15 to determine whether the input key is an automatic scroll request key, and repeatedly performs steps S15 to S21.

On the other hand, if the key input in step S21 is the confirmation key 164, the controller 190 enters the step S23 to execute the item where the current cursor is located.

As described above, the present invention can automatically scroll a list through a simple key operation. This minimizes the inconvenience of the user constantly manipulating keys and manually scrolling through the list.

On the other hand, the list scrolling method of the portable terminal according to the present invention is not limited to the embodiments, various modifications are possible by those skilled in the art within the technical idea of the present invention. For example, in the above-described embodiments, an example is performed in a list in which items are scrolled in an up and down direction, but the present invention is not limited thereto and may be performed in a list in which items are scrolled left and right.

In addition, the above-described embodiments illustrate a list scrolling method performed in the portable terminal. However, in addition to this, the display may be variously applied to all electronic devices having a list in which a plurality of items are listed and displayed. In addition, the various elements and regions in the figures are schematically drawn. Accordingly, the present invention is not limited by the relative size or spacing drawn in the accompanying drawings.

As described above, the list scrolling of the portable terminal according to the present invention can be automatically scrolled through a simple key operation. This minimizes the inconvenience of the user constantly manipulating keys and manually scrolling through the list.
