Benefits of technology

[0045]Since Hangul character input systems that are well known till present arrange vowels regardless of shapes of the vowels to reduce finger movement as much as possible, it is difficult to support a user's intuition. However, the present invention designates consonants in the Korean alphabet as primary characters of keys to input a corresponding consonant when each key is pressed for the first time and designates at least one key, except for the keys to which the consonants are designated, as a vowel enable key to input vowels, thereby minimizing the number of keys for the Korean alphabet. That is, both a consonant and a vowel can be input with a single key by enabling an input of the vowel even through the key to which the consonant has been allocated whe

Problems solved by technology

A problem in such minimized digital devices is insufficient space to input various kinds of information, such as characters.
For example, in a mobile phone, all characters and numerals are designed to be input by using only a total of 12 keys, and inputting information using only this small number of keys is inconvenient and very slow in terms of an input speed, in comparison with using a QWERTY keyboard layout that is widely used as a keyboard layout of a Personal Computer (PC).
However, in spite of this, inputting information into a mobile phone is still inconvenient as the QW

fourth embodiment

4-1

[0160]The current embodiment relates to consonant arrangement to which the vowel input method according to the present invention is applied, wherein consonants are arranged by designating one or two consonants to each key considering the number of actually used frequencies but designating a consonant having a higher use frequency (FIG. 14) as a main character so that the main character is input when each corresponding key is pressed once, and an arrangement order of the consonants is a Hangul consonant order so that users can easily become familiar with the arrangement order.

[0161]Thus, as shown in FIG. 13, consonant arrangement is performed to input all consonants by designating ‘’, ‘’, ‘’, ‘’, ‘’, ‘’, and ‘’ to the ‘1’, ‘2’, ‘3’, ‘6’, ‘7’, ‘8’, and ‘9’ keys, respectively, and designating a function required to input ‘fortis’ besides these consonants to the ‘4’ key. Since a finger press action of the ‘9’ key to which ‘’ is designated is unnatural compared to other keys, it is pr...

fifth embodiment

5-1

[0188]When the input unit 110 according to an embodiment of the present invention includes a device for detecting a touch of a user, such as a touch pad or a touch screen, the present invention allows an initial consonant and a middle vowel to be input by a touch and drag. That is, both the consonant and the vowel can be simultaneously input as a syllable.

[0189]As an example with reference to FIG. 13, ‘’ is input in an existing keypad mobile phone by pressing the ‘1’ key corresponding to ‘’, pressing the ‘5’ key having the vowel input enabling function to input ‘’, and then pressing the ‘4’ key.

[0190]By comparing an input device formed by a virtual keyboard using a touch sensor with such a keypad mobile phone, ‘’ is input by one motion by touching an area corresponding to the ‘1’ key to input ‘’, moving a finger to an area corresponding to the ‘5’ key in a state where the finger is touching the touch sensor (a screen of a touch screen mobile phone) to enable the vowel input enabl...

sixth embodiment

6-1

[0205]Like the consonants, in the case of vowels also, a simple vowel can be changed to a compound vowel by using the selection function key.

[0206]FIG. 20 illustrates this embodiment, wherein an input of ‘’ and an input of ‘’ involve the same trajectory and the same touch-release action but finally performing a touch-release of the selection function key to input ‘’.

[0207]This is considering that the user inputs a vowel in the same manner as a selection of a consonant, simply having an advantage by inputting ‘’ and ‘’ in the same trajectory and the same touch-release action but finally performing a touch-release of the selection function key to input ‘’, and providing a method of correcting an error input of ‘’ with only the touch-release of the selection function key without correcting the error input of ‘’ in the first place even though ‘’ is input by mistake in the processes of FIGS. 19( ) to 19( ).

[0208]In addition, as shown in FIG. 17, a method of performing a touch-release ...

Abstract

The present invention relates to an information input system and method using an extension key. The information input system comprises: an input unit including a plurality of divided regions, for detecting a user selected divided region among the plurality of divided regions; and an input analysis unit for allocating corresponding information to the plurality of divided regions, and analyzing, if the input unit detects a user selected divided region among the plurality of divided regions, whether or not information allocated to the divided region is input. The input analysis unit allocates an extension key to at least one divided region out of the plurality of divided regions; and once the extension key is selected, the input analysis unit allocates new information to an extended region which is a divided region determined according to the extension key.

Description

TECHNICAL FIELD[0001]The present invention relates to a system for inputting information by utilizing an extension key and a method of inputting information using the same. In detail, the present invention has a feature that new items are allocated to an extension area when an extension key is included in an input system of a minimized digital device and this extension key is selected so that a user can input newly allocated information.BACKGROUND ART[0002]Recently, many minimized digital devices, such as mobile phones and game systems, are available in the market for use.[0003]Such minimized digital devices win preference because of their advantage of portability and anytime, anywhere use, and due to this, even in the future various products will be minimized and manufactured.[0004]A problem in such minimized digital devices is insufficient space to input various kinds of information, such as characters.[0005]For example, in a mobile phone, all characters and numerals are designed ...
