Abstract

A key input control method of a mobile communication terminal and a device are provided to determine an available command even though undesired key data is inputted by wrong operation when a key is inputted, thereby minimizing an inputting error. If key data is inputted from a key input unit of a terminal which is in standby state(S11,S12), a key input decider decides whether the key data is inputted from a dome key(S13). If not, the decider decides whether the key data is inputted from a touch key(S14). If so, the decider waits for a certain time(S15). If key data is inputted from the dome key(S16), a touch key processor which receives the key data from the key input decider performs a command for the key data to process the command(S17).

To this end, the key input unit 160 according to the present embodiment includes a basic key 162, a touch key 164, and a dome key 166. The basic key 162 is a key for inputting numeric and text information, and the touch key 164 and the dome key 166 are keys for controlling the operation of the mobile communication terminal 100.

2 is a diagram schematically illustrating a key input unit according to the present invention, in which only a touch key and a dome key according to the present invention are illustrated, and a basic key is omitted.

Referring to FIG. 2, a touch key 164 is disposed around the dome key 166 around the dome key 166. The touch key 164 according to the present embodiment is a touch switch that operates when the human body contacts, and the dome key 166 is formed in a dome shape to perform an elastic movement in up and down directions when pressed. It is a mechanical switch. However, the present invention is not limited thereto, and various applications may be possible, such as configuring the dome key 166 located at the center as the touch key 164.

Referring back to FIG. 1, the storage unit 170 includes a program memory and data memories. The program memory stores programs for controlling general operations of the mobile communication terminal 100. Data generated during the execution of programs is stored in the data memory.

The controller 190 performs an overall control operation of the mobile communication terminal 100. In addition, when the key data is input from the key input unit 160, the controller 190 selects a valid key and performs a corresponding command. To this end, the controller 190 according to the present invention includes a key input receiver 192, a key input determiner 194, a touch key processor 196, and a dome key processor 198.

The key input receiving unit 192 receives the input key data when the user inputs a key by operating the key input unit 160.

The key input determination unit 194 receives the key data received from the key input reception unit 192, and based on this, the key input determination unit 194 determines a valid key that the user actually wants to input from the touch key 164 and the dome key 166. Do it.

When the touch key processing unit 196 determines the touch key 164 as a valid key by the key input determination unit 194, the touch key processing unit 196 processes a command for the corresponding touch key 164.

When the dome key processing unit 198 determines that the dome key 166 is a valid key by the key input determination unit 194, the dome key processing unit 198 processes the command for the dome key 166 by deactivating the touch key 164. An operation process of the dome key processing unit 198 will be described in more detail in a key input control method to be described later.

Next, a key input control method of the mobile communication terminal 100 according to the present invention will be described in detail with reference to the following embodiments. The configuration of the above-described mobile communication terminal 100 will also be clearer from the following description of the key input control method.

3 is a flowchart illustrating a key input control method according to an embodiment of the present invention.

Referring to Figures 1 to 3 as a whole the key input control method according to the present invention will be described. When key data is input from the key input unit 160 of the mobile communication terminal 100 in the standby state (S11) (S12), the key input receiving unit 192 of the controller 190 receives the key input determination unit 194. To send.

The key input determination unit 194 determines which key data is transmitted from the dome key 166 and the touch key 164. In this case, since the primary key 162 is processed to perform the corresponding command in the same manner as in the related art, a description thereof will be omitted (S22).

When the key data is input from the dome key 166, the key input determination unit 194 determines the valid key as the dome key 166, and transmits the key data to the dome key processing unit 198 (S13).

When the key data is transmitted, the dome key processing unit 198 quickly deactivates the touch key 164 (S18). This is to prevent the touch key 164 from operating at the same time by accidentally touching the touch key 164 when the user operates the dome key 166.

The dome key processing unit 198 deactivating the touch key 164 performs a command on the transmitted key data and processes it (S19). In this process, the touch key 164 continues to be inactivated. However, in addition to the method of deactivating the touch key 164 during the command processing, the touch key 164 is inadvertently operated such as deactivating the touch key 164 only for a predetermined time from the moment when the dome key 166 is input. Various methods can be used if it can be prevented.

Subsequently, the dome key processing unit 198 determines whether all commands for the dome key 166 have been processed (S20), and when the processing is completed, reactivates the touch key 164 that has been deactivated (S21). Accordingly, the mobile communication terminal 100 maintains the standby state again.

On the other hand, if the key data input to the key input determination unit 194 is the touch key 164 (S14), the key input determination unit 194 waits for a predetermined time and goes through the process of waiting for input of other key data. (S15).

According to the present invention, when a user wants to operate the dome key 166 but accidentally contacts the touch key 164 in the process of manipulating the dome key 166, a key input is ignored. Provide a control method. That is, in the present invention, before the dome key 166 is completely pressed while the user presses the dome key 166 using a finger, the user's finger is touch key around the dome key 166 before the corresponding key data is input. The contact with 164 prevents the corresponding key data of the touch key 164 from being processed first.

Therefore, when key data input is generated from the touch key 164, the key input determination unit 194 of the present invention verifies whether the touch key 164 is substantially a valid key that a user wants to input or the dome key 166 is valid. A predetermined time is waited to determine whether the key is a key, and the key data input of the dome key 166 is waited for.

In this embodiment, the time for waiting for the key input determination unit 194 is set to about 100 ms. When the touch key 164 is first input in a situation where the dome key 166 is to be input, the touch key 164 is set according to a general time interval in which the touch key 164 and the dome key 166 are sequentially input. It is not.

When key data is input from the dome key 166 for 100 ms while the key input determination unit 194 waits (S16), the key input determination unit 194 uses the touch key 164 previously input by a user's mistake. Judging by the keystrokes and ignored. The dome key 166 input at the waiting time is determined as a valid key.

When the key input determination unit 194 determines the dome key 166 as a valid key, the key input unit 160 transmits the key data for the dome key 166 to the dome key processing unit 198. The dome key processing unit 198 performs the above-described process S18 to S21 and processes the corresponding command.

On the other hand, when there is no input from the dome key 166 during the waiting time of the key input determination unit 194 (S16), the key input determination unit 194 actually inputs the touch key 164 by the user. The touch key 164 is determined to be a valid key.

The key input determination unit 194 transmits the key data of the touch key 164 input to the touch key processing unit 196, and the touch key processing unit 196 receiving the key data from the key input determination unit 194. Process by performing a command on the key data (S17).

As described above, according to the present invention, when the touch key is input, it is determined whether the input touch key is a valid key substantially desired by the user, and then performs the corresponding command. In other words, even if a user misoperates when a key is input, a valid command is determined and then executed, thereby minimizing an input error.

On the other hand, the key input control method and apparatus of the mobile communication terminal according to the present invention is not limited to the embodiment, various modifications are possible by those skilled in the art within the technical idea of the present invention. For example, in the present embodiment, the dome key illustrates a key input unit located at the center of the touch key. However, the present invention is not limited thereto and may be applied to any type of key input unit in which a specific key is arranged in parallel with the touch key. In addition, although the present embodiment shows an example applied to the mobile communication terminal, it can be variously applied to all electronic devices having a touch key. 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 method and apparatus for controlling key input of a mobile communication terminal according to the present invention determine a valid key through a process of determining whether a user is a desired valid key with respect to input key data, and then determine the valid key. Perform the corresponding command for.

Therefore, even when unwanted key data is inputted by a user when a key is input, a valid command can be determined, thereby minimizing an input error.
