Description

{Apparatus for inputting character and numeral on communication device}

The present invention relates to an alphanumeric input device of a communication terminal

More specifically, a plurality of keypads (or buttons) integrated in a communication terminal are provided in one piece, four or more signal sensing units are installed, and multiple signal key input means capable of fine movement in four or more directions. Hereafter, 'keypad body' can be used to easily input a text signal, and the letter / number of the communication terminal that can significantly lower the manufacturing cost than various terminals applying the existing joystick / navigation key / switch principle. It relates to an input device.

Recently, with the rapid development of communication technology, communication terminals such as mobile phones, PDAs, pocket PCs, Internet terminals, etc., which enable an individual to perform voice and data communication while moving, have been developed and widely used. In particular, thanks to the technical development of the general personal wireless communication service and the rapid increase in the number of subscribers, various additional services have been developed and are being actively serviced. Among these additional services, the text transmission service is of particular interest to users due to the specificity of performing the text transmission function through the voice communication terminal.

In order to provide such a text transmission service, a useful text input device that can be easily input through a reduced text keyboard such as an electronic keypad is required.

Applications of the miniature character keyboard include small general keyboard systems such as Palm Top computers that require fewer keyboards, keyboard systems as substitutes for keyboard input devices such as Internet TVs, digital cameras, PDAs, and electronic notebooks. An input system with a structure and function similar to a guide kiosk, an electronic lock, an ATM, and the like installed in a building or other location where a guide is needed.

In order to provide a text transmission service using a reduced-character keyboard that has a limited number of key buttons, such as an electronic telephone keypad, the consonants / collections of the languages to be supported are effectively overlapped or the function keys are operated. By means of the user's intention, you should be able to quickly combine the consonants and vowels of the desired character.

Accordingly, various character input systems have been developed and used to meet the technical needs as described above. However, the previous techniques related to the character code input method using the electronic telephone keypad have mixed character layout of the keypad. There was an inconvenience in acknowledging the keyboard, and there was a problem such as inputting an end mark character every time a combination of one character was completed. Recently, character input devices and methods designed to complement the existing problems to a certain extent can be seen that the increase in manufacturing cost has been pointed out. The decision is not made.

Looking at an example of the recently designed character input device by type,

In the case of applying the principle of joystick which is used in game, we can see that the 12 keys of the communication terminal are replaced with 12 small joysticks instead of the existing keypad so that each key has directionality. Since the text can be output by manipulating in various directions, the text input speed is much faster while using a smaller area more efficiently than the conventional keypad method. However, by replacing all keypads with joysticks, manufacturing costs are expected to increase, which will cause problems in the spread and spread of handsets. In addition, in order to mount each joystick, 12 spaces (in case of 12-key arrangement) should be secured enough for 12 joysticks to move enough, and at least 48 signal detection units for detecting the operation signals of 12 joysticks and 12 joysticks are required (12X4) should be provided, which is pointed out as a factor of increasing the size of the mobile communication terminal, and because of the large number of joysticks to operate, it may be a cause of frequent failures during long time operation. In other words, replacing all 12 keys of a mobile communication terminal with a joystick-type keypad will not only increase the manufacturing cost but also increase the size of the terminal and frequently cause breakdown problems when used for a long time. It is expected.

In the case of applying the principle of the navigation key, one navigation key on the terminal is configured to be operated diagonally up, down, left, and right, and thus a desired character is selected and output by moving the cursor displayed on the screen. At this time, the user has to find the desired character on the screen by moving the gaze, and then the user needs to move the cursor to the character, and there is inconvenience of waiting for the cursor to reach the desired character. Of course, since only one navigation key and four signal detectors need to be installed, the number of breakdowns and manufacturing cost is lower than that of the joystick keypad terminal, which requires the installation of 12 joysticks and 48 signal detectors. This can be said to be efficient.

In the case of applying the switch principle, one or two switches that can be operated in up, down, left, right, and diagonal directions as in the navigation key method are installed in the terminal to arrange characters in each direction to output characters according to the operation direction. The number of failures and cost is lower than that of the joystick-type keypad terminal, and the character input time is faster than that of the navigation key.However, one or two switches have limitations in the direction of operation. It is not practical because it cannot be done.

The character input apparatus using the electronic telephone keypad according to the prior art enumerated above is extremely different from the character input system provided by a general word processor, and thus has a problem of degrading user friendliness. When assigning the letter of the letter, even if you use the key arrangement structure with the orderly regularity, it is not only requires a lot of effort for the user to know it, but also has a problem that the key operation is difficult to master.

In addition, recent character input devices using joystick keypads, character input devices using navigation key keypads, and character input devices using switch keypads have increased manufacturing costs, increased terminal size, frequent failures during long-term operation, input speed, and operation direction. There was a problem such as a limitation.

Overcoming the limitations of the display and input method for the function as a multi-media device that users really want in the IMT-2000 terminal that will be used for the wireless network that exchanges data between users in the next generation video mobile phone business. The most important thing is that the cost effective and useful character input device plays a big role because the terminal manufacturers must be able to produce the product without great risk.

The purpose of the present invention is to solve the above-mentioned problems, a plurality of keypad (or buttons) provided in the communication terminal is integrally formed, four or more signal detection unit is installed, fine movement in four or more directions By using this multi-signal key input means (hereinafter, abbreviated as 'keypad body'), a text signal can be easily inputted, and a letter / number input of a communication terminal for greatly reducing the manufacturing cost of a communication terminal and reducing a failure rate To provide a device.

Another object of the present invention is to provide a character / numeric input device of a communication terminal to increase a character / number input speed by allowing a user to input up to two or more phonemes by only one operation of the keypad body. There is.

In the description of the present invention, as the example of the character of a specific language is assigned to the keypad body 1, it is determined that the embodiment of FIG. 3 is sufficient, and further description thereof will be omitted.

3A illustrates an embodiment in which a character is implemented by combinations of a keypad body and a keypad / button signal input in a method of inputting a character / number using a keypad body of a character / number input apparatus of a communication terminal according to the present invention; It is a chart showing.

Of course, it is not a literal combination actually used, but only to assign the letters in the lexical order of the Roman alphabet to explain how the letters are formed in the present invention.

Next, an embodiment of a letter / number input method of a communication terminal according to the present invention configured as described above will be described in detail with reference to FIGS. 4 to 5.

4 to 5 are flowcharts showing in detail the operation of the letter / number input method of the communication terminal according to the present invention.

First, it is determined whether the user selects a language-specific character mode by pressing a character mode key of the keypad body 1 provided in the communication terminal (S100), and after the corresponding user selects a language-specific character mode, Korean, Roman characters, and Japanese Ghana It is determined whether an input mode is selected from among characters used in each country of the world such as characters and Chinese (S200).

For example, a character mode key operable by eight directions of the keypad body 1 and a pressing operation of the keypad (or button) 2 is a keypad (or button) 2 in which a character mode menu is set, Assuming that the Hangul input mode, Roman input mode, Japanese input mode, and text storage mode are set in the direction of the mode key up, down, left and right, it is determined that the user selects the character mode when the user presses the character mode key. If you operate the text mode key upward, the keypad body (1) will slide upward. If you select the text mode key downward, the keypad body (1) will slide downward. Will be judged.

As a result of the above-described determination (S200), when the user selects a specific character input mode, the communication terminal is a key for the user to operate the keypad body 1 and the plurality of keypads (or buttons) 2 in various directions. The signal is detected and the characters / vowels and numbers / symbols of the corresponding characters are read and combined to be displayed on the screen of the communication terminal (S300).

In detail, for example, in the Roman alphabet, the communication terminal switches to the Roman input mode according to a user's selection and is placed in the Roman input mode (S305). For example, when the keypad body 1 is moved by manipulating the call keys of the keypad up, down, left, and right, it is determined whether a menu for erasing characters, outputting blank characters, inputting numbers and symbols, and selecting a line feed is selected (S310).

As a result of the determination, when the user selects any one menu among erase text, output blank characters, input numbers and symbols, and replace lines, the communication terminal performs the corresponding menu selected by the user and repeats the above-described step (S310). (S315).

However, as a result of the determination in step S310 described above, if the user does not select any one menu among erase text, output blank characters, input numbers and symbols, and replace lines, the communication terminal may be configured to include the keypad main body 1 and the user. It is determined whether specific consonants and vowels are selected by operating specific keys provided in the plurality of keypads (or buttons) 2 in various directions (S320).

As a result of the determination, a Roman letter combining consonants and vowels corresponding to the direction of a specific key manipulated by the user is displayed on the communication terminal screen, and the process is repeated after step S310 (S325).

Now, through the above-described process (S300), the user inputs the character through any one of the input modes, such as Hangul input mode, Roman input mode, Japanese Ghanaian character input mode, Chinese input mode, etc. When the terminal terminates, the communication terminal determines whether the corresponding user selects a key signal for storing the text (S400).

As a result of the determination, when the user selects the storage key for the text storage, the communication terminal stores the text input by the user (S500), and if the user does not select the storage key for the text storage, the user selects the text mode. It determines whether to terminate or continue or release the character mode (S600).

As described above, according to the character / number input device of the communication terminal of the present invention, the consonant / vowel character arrangement structure of each of the keypad body and the plurality of keypads (or buttons) provided in the communication terminal is configured to be easy for the user to understand. At the same time, users can quickly and easily input characters used in various countries of the world, such as Korean, Roman, Japanese, Ghanaian, and Chinese, with simple key operations. Internet information retrieval can be implemented, and it is possible to save expensive communication cost by maximizing the input speed of letters and numbers while providing a lot of convenience to the user.

In addition, it is possible to overcome the problems such as manufacturing cost increase in the joystick type / navigation key type / switch type keypad terminal, terminal size increase, frequent failure causes during long time operation, input speed, and limitation of the operation direction.

Herein, while the present invention has been described with reference to a preferred embodiment, those skilled in the art will variously modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. And can be changed.
