Problems solved by technology

[0011] However, this type of input device is inconvenient for the user that it must always be carried
Meanwhile, since such input devices have a problem that characters can be input only in a state where these types of input devices are placed on the bottom surface, the type of input devices is not suitable for application to personal portable information terminals that require Enter characters while holding a personal portable information terminal while moving

[0119] The following will refer to Figure 4 and Figure 5 , the basic input operation of the character input device 1 having the above-mentioned configuration according to the present embodiment will be described in detail.

[0120] The term 'character' used here means to represent a consonant or vowel in each national language such as the Korean (Korean) alphabet, the English alphabet, the Japanese alphabet, etc., and is defined in a narrower sense as including numbers, symbols etc.

[0121] refer to Figure 4 Eight direction indicating parts 50 a to 50 h are provided equidistantly at different circumferential positions radially outward from the reference input part 30 and spaced apart from each other. A character is assigned to each direction indicating portion 50, so that when any contact is sensed for the associated direction indicating portion 50a, the control unit can retrieve from the memory unit the character code assigned to the sensed associated direction indicat...

[0186] Next, refer to Figure 13 A second embodiment of the input operation of the character input device 1 according to the present invention is described in detail.

[0187] Such as Figure 13 As shown, in this embodiment, input lines connecting eight direction indicating parts 50a to 50h are provided. However, since the input lines are provided only for the user's convenience, the input lines can also be omitted due to the direction indicating portions 50a to 50h.

[0188] Such as Figure 4 As shown in (a), with respect to the direction indicating parts 50a to 50h, by contact with each direction indicating part (contact point ①), inward movement of the contact point passing the direction indicating part (inward touch input ②), and passing through The outward movement of the contact point of the direction indicating part (outward contact input ③) can input different characters.

[0189] For example, a consonant character may be assigned to a contact input with respect to...

[0192] Next, refer to Figure 14 and Figure 15 A third embodiment of the input operation of the character input device 1 according to the present invention will be described in detail.

[0193] exist Figure 14 In , various input operations with respect to each direction indicating part 50 are shown, that is, as Figure 14 As shown in (a), the characters assigned to each direction indicating portion 50 are input through contact with each direction indicating portion 50; Figure 14 As shown in (b), the characters are input by moving the contact point from the reference input part 30 to each direction indicating part 50; and as Figure 14 As shown in (c), characters are input by moving the contact point from the outside of each direction indicating portion 50 to each direction indicating portion 50 .

[0194] Optionally, as in Figure 14 As shown in (d), characters are input by the outward movement of the contact points from the respective direction indicating parts 50 . ...

Abstract

The present invention relates to a character input device which allows all the characters which it is desired to input to be arranged in a minimum input region so as to be suitable for miniaturization, as well as allows each of the arranged characters to be input through only one4nput operation so as to enable rapid and correct input of a character. The character input device includes a base having an input region; one or more sensing sections provided at the input region for sensing a contact with the input region or a contact movement to the input region; and a control unit for extracting data corresponding to each input operation from a memory unit (not shown) and inputting the extracted data, according to the position of a contact point or the movement direction of the contact point sensed by the sensing section relative to a reference input section provided at the input region.

Description

technical field [0001] The present invention relates to a character input device, and more particularly, to a character input device that allows all characters desired to be input to be set in a minimum input area to realize miniaturization, and allows each set character to be input by only one input operation. Background technique [0002] With the development of software and semiconductor technology and information processing technology, information devices are gradually becoming smaller, and the amount and importance of character input using such information devices are gradually increasing. [0003] However, such information devices cause many problems when various characters or instructions are input to such information devices. For example, an input device such as a keyboard used in a personal computer (PC) or a notebook computer makes it difficult to downsize the information device. Therefore, the input device makes it difficult to miniaturize the information device....
