Preferably, the operation command is an operation mode change and direction movement command.

Preferably, the priority table according to the operation is generated by generating and calculating frequency data according to a key operation.

Preferably, the control unit controls to perform a final operation by applying to the priority table for each mode when an incorrect key operation input.

Preferably, the control unit stores key operation data of the first user and controls to generate a priority table by calculating a frequency of a key used in a corresponding mode.

Key control method in a mobile terminal according to the present invention for achieving the above object comprises the steps of detecting a key operation; Determining whether an incorrect operation is input; Checking a key operation based on a priority table for each mode if an incorrect operation is input as a result of the determination; And performing a final operation by the mode-specific priority table.

Preferably, the step of generating the mode-specific priority table comprises: detecting a key operation; Identifying a current operating mode; Calculating a frequency of use for a direction and an operation mode of a key by the key operation; Assigning a high priority to a key with high usage rate; Generating a table of key priorities.

Referring to the accompanying drawings, a key control apparatus and method in a mobile terminal according to an embodiment of the present invention as described above are as follows.

Referring to FIG. 1, the portable terminal records and stores a key input unit 102 and a plurality of multimedia files for receiving a mode change and function operation command by a user, and stores a data table for a user's key operation. A storage unit 104, a display unit 106 for displaying a state according to the operation command execution, a receiver 108 for receiving a broadcast signal, and an A / D converter for converting an analog signal input through the receiver into a digital signal ( 110 and the user according to the mode by storing the frequency of the key operation of the user input through the audio processing unit 112 and the key input unit 102 for outputting the input broadcast signal or the audio file stored in the storage unit 104 It comprises a control unit 102 for controlling to configure and store the key use priority table of the.

The key input unit 102 includes one of a direction key, a selection key, a mode selection key, a volume control key, and a jog dial.

The storage unit 104 is a memory of a mobile terminal, and stores data on a key selected when a user inputs a key, and the control unit 114 calculates the frequency of key use by referring to the data, thereby providing a key priority table. Once created, the table is saved.

2 is a diagram illustrating a configuration of a key input unit according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the key input unit 102 includes a direction key for moving up, down, left, and right, and a jog dial for performing direction and selection commands.

In the case of a direction key composed of a button type, when two or more buttons are pressed at the same time, it is difficult to execute an accurate command.

When the movement command is executed using the jog dial, it is not easy to determine exactly which direction to select when the direction key is moved diagonally.

3 is a flowchart illustrating a process of generating a key priority table for each operation mode according to an exemplary embodiment of the present invention.

Referring to FIG. 3, when a user performs an initial key operation command, a key operation is detected (S300).

When the key operation is detected, it is checked in which mode (S302).

The direction and operation mode data of the key in which the key is operated are generated (S304).

When the user's key operation data is generated for a predetermined time, the key direction and operation mode are stored and the user's key use frequency is calculated (S306).

When the operation is completed, a high priority is assigned to a key with a high frequency of use according to the operation mode (S308).

Accordingly, the key priority data table is generated according to the operation mode (S310).

The configuration of the above priority table will be described with reference to Table 1.

Operation mode ↑ ↓ → ← Music play mode 20 3 60 30 Radio mode 5 15 One 40 Video play mode 50 2 30 10

The numerical values shown in Table 1 were digitized by checking the frequency of using the direction keys according to the mode when the user first started to operate the keys.

When the frequency of key input by the user is configured as shown in the table above,

If the up and right arrow keys are pressed simultaneously in the music playback mode, the frequency of the up arrow key is 20 and the frequency of the right arrow key is 60, so the final action of the input key assumes that the right arrow key is selected. Perform the action.
