Abstract

The present invention is to simply input Hangul by significantly reducing the number of touches. An one-handed Hangul input method using multi-touch comprises the following steps: calling an input key group composed of consonants; determining a type of a vowel or a medial phoneme by a dragging gesture performed in a random space on a touch screen; displaying a plurality of input keys in which a consonant is coupled to the vowel; selecting, by a user, any one of the input keys or an input key in which initial and medial phonemes are coupled; calling the input key group composed of consonants; and selecting an input key in which initial, medial, and final phonemes are coupled by starting a new syllable input by the dragging gesture performed in the random space on the touch screen or selecting any one of the input keys by the user.

Description

METHOD OF SINGLE HANDED HANGUL INPUT USING MULTI-TOUCH [0002]

The present invention relates to a one-handed Korean input method using multi-touch, and more particularly to a Korean input device using an ultra-small touch screen.

Recently, electronic devices have been miniaturized and a touch screen has become a core technology, so that a new character input method that can replace an existing input key is required. Particularly, Korean people are much more likely to input Korean characters than when they input English characters. Therefore, it is urgent to develop a reduced character input apparatus provided with a keypad designed to easily input Korean characters. Korean Patent Laid-Open No. 1999-65826, which is known in the art, is constituted by a phoneme combination method. Although it is easy to learn a method of writing a letter by using the concept of writing a phoneme, many phrases are required in the vowel composition. In addition, Korean Patent Publication No. 1999-52447 is constituted by a visual reinterpretation, and since the Korean alphabet must be reconstructed by reconfiguring the consonants, the system deviates from the basic configuration of Hangul, There is an inconvenience that can not be easily learned.

In this background, in particular, Korean Patent Registration No. 1010857020000 discloses a method of efficiently inputting Hangul by a minimum operation, but a method of inputting a vowel by selecting a consonant by touching and dragging, And there was a difficulty in use. (It is difficult to input a vowel in the case of a consonant near the bezel)

That is, the conventional Hangul input method has a problem that it is not suitable for a wearable device such as a clock, a glasses type and the like due to a large number of touches or complicated keyboard layout.

In this background, there is a need for a method for quickly and accurately inputting Hangul characters on a miniature multi-touch screen. In addition, a Hangul input method that users can easily learn is needed.

An object of the present invention is to simplify Hangul input by drastically reducing the number of touches.

An object of the present invention is to input Korean characters effectively using a limited space of a touch screen.

In order to accomplish the above object, a representative structure of the present invention is as follows.

According to an aspect of the present invention, there is provided a one-handed Hangul input method using multi-touch, comprising: calling an input key bar composed of consonants; Determining a vowel shape or neutrality by a dragging gesture performed in an arbitrary space on a touch screen; Displaying a plurality of input keys coupled with consonants in the vowel; Selecting one of the plurality of input keys by a user or selecting an input key having a combination of a prefix and a neutral; Calling an input key bar composed of consonants; A new syllable input is started by a dragging gesture performed in an arbitrary space on a touch screen or one of the plurality of input keys is selected by a user so that an input key having a combination of a prefix and a neutral is selected; A method of inputting a one-handed Hangul character using multi-touch is disclosed.

Other configurations may be further provided in accordance with the technical idea of the present invention.

According to the present invention, it is possible to minimize a character input key disposed on a touch screen used in a micro mobile device, and to combine Hangul characters by a minimum touch operation in Hangul input, thereby simplifying the input action of Hangul input Accordingly, it is possible to shorten the input time of the Hangul input and effectively utilize the limited touch screen area.

Basically, in the present invention, a method of connecting the direction of the swipe to the directionality of the vowel and the number of touches to the singularity of the vowels is adopted, but the directionality is the direction of the gesture / the tilt of the device / the direction of movement of the device, The speed of the swipe, the number of touches, the pressure, etc., to start a new configuration.

Generally, most Korean input methods use a method of inputting a pre-neutral-end note, but in the present invention, a method of inputting a vowel is firstly selected. This is because unlike the conventional method, when a wearable device or a small screen is used, the consonant causes inconvenience such as hanging at the end of the screen, and the vowel input is started at an arbitrary place and increased in freedom in consideration of a narrow screen. However, it is also possible to construct a pre-neutral-neutrality configuration according to the user's convenience.
