Description

Character input device of a terminal and a terminal including the same {Character entering device and terminal comprising the same}

The present invention relates to an apparatus for inputting a character of a terminal, and more particularly, to an apparatus for inputting a character into a tablet PC or a smartphone and a terminal including the same.

Recently, in the mobile business, smartphones are emerging as new products as the center of the mobile industry is shifting from voice-oriented communication to data communication due to the advancement of the network and the development of terminal technology, especially the SoC technology. In 2007, Apple launched the iPhone, which provides innovative UI (User Interface), and the world market is paying attention to smartphones as the next-generation mobile communication terminals. .

Smartphones do not require consumers to purchase additional modules, they do not have to be structurally similar to mobile phones or PDAs, they must be small and light, provide voice communications, have PIM (Personal Information Management) capabilities, and have network capabilities. Should have

Smartphones provide various services to users, including mobile phone functions, network technology and personal information management functions of personal digital assistants (PDAs), MP3, wireless Internet services through WiFi, and QWERTY.

Like this, smartphones have a somewhat contradictory feature that needs to be small and light in a variety of functions, and to be able to express everything on a small screen. In particular, since the input function and display function of the character on the screen called the touch screen is realized, efforts are being made to secure wide visibility in the smart phone.

The keypad used when performing an input function on a touch screen of a smartphone displays all letters and numbers to input letters and numbers through touch. Most of these keypads occupy half of the width of the touch screen, and in spite of the wide interview of the touch screen, letters have consonants, vowels, numbers, and English in various and complex ways, and thus touch errors occur. Is occurring.

In addition, when a character or a number is inputted, a plurality of touches must be accompanied until one letter or number can be input, which causes a lot of time.

Hangeul consists of 10 vowels except 19 consonants and vowels. Such consonants and vowels are expressed in various ways using two symbols as in the character input device of the present invention. Among them, an embodiment of the present invention will be described through the embodiments shown in FIGS. 3 and 4.

It is emphasized that the invention is not limited to the arrangements arranged in FIGS. 3 and 4.

The controller of the present invention is characterized by displaying a consonant array table arranged in eight directions when a touch that has passed unit time has been detected on the consonant input symbol, and detecting a touch that has passed unit time on the vowel input symbol. In this case, the vowel array table arranged in four directions is displayed on the display area of the touch screen.

The unit time is a time that can be set arbitrarily and may be set to a time of 0.1 second to 1 second. When the touch that has passed the unit time for the consonant input symbol is detected by the input sensing unit, the input is transmitted to the controller, and the controller displays consonants arranged in eight directions around the consonant input symbol on the touch screen. do. In addition, when the touch that has passed the unit time for the vowel input symbol is detected in the input sensing unit, the vowels arranged in four directions around the vowel input symbol are displayed on the touch screen.
