The present invention relates to an input keypad guidance method of a terminal and a terminal using the same.

Recently, with the rapid development of communication technology, various functions have been added to a mobile communication terminal or a wired / wireless telephone to provide convenience to users.

As one of the various functions as described above, a command for performing various functions is input through a keypad of a phone, and research efforts are being actively conducted to provide convenience thereof.

FIG. 1 is a view schematically illustrating a liquid crystal display and a keypad of a telephone body in order to show a keypad recognition method of a conventional telephone.

Referring to FIG. 1, in the conventional keypad recognition method of a telephone, a "save?" Is stored in the liquid crystal display 102 of the telephone main body 101 according to a user's command input. Or "Are you sure you want to delete?" In order to respond, the user must view the telephone manual, press the <Save> key to delete, or press the <Exit> key to cancel.

In addition, the conventional telephone is designed to brighten the entire keypad 103 using a light emitting element (LED), and no light emitting element is assigned to each individual keypad.

2 is a flowchart illustrating a keypad recognition process of a conventional telephone.

Referring to FIG. 2, it is determined whether a situation requiring a user's key input occurs in an initial state (step 201) (step 202), and if a key input is required, the user inputs a key (step 203).

However, in the conventional telephones as described above, when a terminal user's response is required through a keypad in a specific state, not all keypads are generally used, but only a few keypads necessary for response are used.

Nevertheless, the light emitting devices applied to the conventional terminals only perform a function of brightening the entire keypad, and cannot distinguish the keypad through the light emitting devices.

In addition, since the number of keypads is limited in the telephone, a specific function is often assigned to a keypad that is difficult to convey meaning as in the following example, and thus, the user may have to memorize such a function or have to look at a manual.

Ex) Do you want to delete this message? And assign "<save> keypad to" <yes> "and" <exit> "keypad to" <no> ".

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an input keypad guidance method of a terminal capable of increasing a keypad user's recognition rate by allocating an individual light emitting device to each keypad of the terminal and a terminal using the same The purpose is to provide.

In order to achieve the above object, the input key guide method of the terminal according to the present invention,
Determining whether a user's key input is required to perform a predetermined function of the terminal;
Distinguishing one or a plurality of key sets to be input by the user when the key input of the user is required as a result of the determination; And
And performing an input key display on a keypad corresponding to the separated one or a plurality of sets of keys.
In addition, the input key guide terminal according to the present invention to achieve the above object,
A key pad unit including a plurality of key pads for inputting numeric keys and function keys and light emitting elements provided in the respective key pads;
In the case where a user's key input is required according to a function performed by a telephone, one or more sets of keypads to be input by the user are classified from among a plurality of keypads provided in the keypad, and the divided one or And a controller configured to control the light emitting devices provided in the plurality of keypad sets to emit light.

3 is a diagram schematically illustrating a structure of a telephone system for implementing an input key guide method of a terminal according to an embodiment of the present disclosure.

Referring to FIG. 3, a telephone system according to an exemplary embodiment of the present invention may include a main controller 302 including a liquid crystal display 301, a microprocessor 302-1, and a universal interface 302-2, and a plurality of A key pad portion 303 including a keypad and a light emitting element, a memory portion 304, and a peripheral device 305 are included.

Hereinafter, a case in which the input key guidance method of the terminal according to the present invention is applied to a telephone will be described in detail with reference to the accompanying drawings.

First, in the telephone, when a message indicating that the user's response is required through the keypad in a specific state is displayed on the liquid crystal display device 301, the entire keypad is not required for the response, and several keypads required for the response are required. Only will be used.

At this time, only the LED of the keypad that can be used is turned on (ON) under the control of the main controller 302. By turning on only the light emitting elements (LEDs) of the keypad that can be used in this way, it is possible to clearly indicate to the user the keypad required for the response to the LED.

4 is a flowchart illustrating a keypad guide process of a phone according to an embodiment of an input key guide method of a terminal according to the present invention.

Hereinafter, the input key guide method of the terminal of the present invention will be described in more detail with reference to FIG. 4.

First, in an initial state (step 401), it is determined whether a message indicating that a user's key input is required is displayed on the liquid crystal display of the telephone (step 402). If it is determined in step 402 that the user's key input is necessary, it is again determined whether the keypad is required for user input (step 403).

Here, the division of the keypad for command input means, for example, a blue LED if the response to the message displayed on the LCD is positive, a red LED if the negative is assigned, or all characters and vowel keys in the Hangul input state. If you need to see all the pads instead of consonants, the LED of the keypad with the consonant is turned on, if the vowel is needed only LED keypad with the vowels turned on, all of the consonant keypad is off This makes it easier to recognize the keypad for key input.

In particular, in the Hangul input state, the consonants, vowels, and final consonants of the Hangul become consonants, vowels, and consonants. Therefore, in edit mode, only the LEDs of the consonant keypads are initially turned on. Once turned on and the vowel is input, you can easily tell the user which key pads to choose by repeating the LEDs on the consonant keypads again.

5 is a view illustrating an LED operation of a keypad when inputting a Hangul in the input key guide method of the terminal according to an embodiment of the present invention described above.

As a result of the determination in step 403, when the keypad is required for command input, the LED of the corresponding keypad is turned on according to the necessary condition (step 404).

After that, the user selects a keypad to be input by the user from among the keypads that are turned on (step 405).

However, if it is determined in step 403 that no distinction is required for the keypad, the system displays the keypad with a default value determined by the system (step 406).

The keypad recognition method of the present invention has been described only for a mobile communication terminal or a wired or wireless telephone, but those that can be easily implemented in various fields by those skilled in the art based on the present invention are included in the scope of the present invention. There will be.

As described above, according to the input key guidance method of the terminal of the present invention and a terminal using the same, an individual light emitting device is assigned to each of the keypads of the terminal, and the user's keypad recognition rate is increased to provide convenience to the user. It works.
