The present invention relates to a character input device capable of distinguishing an input direction by a touch, and more particularly, a first direction indicating position and a second direction indicating position which are formed in a recessed manner and inserted into a plurality of radially by inserting a finger into the input unit. By providing a tactile application structure that can input the first direction indication position and the second direction indication position separately from each other in contact with the position, inputting accurately and quickly without interference when inputting direction for each indication position. The present invention relates to a character input device capable of distinguishing input directions by means of touch.
Recently, with the development of software, semiconductor technology, and information processing technology, information devices are becoming smaller and smaller, and the input of characters in various information devices is also increasingly important.
However, many problems have been revealed in the input of various characters or commands in such information devices.
For example, input devices such as keyboards used in personal computers (PCs) or notebooks (Notebooks) have limitations in reducing their size, which makes it difficult to miniaturize these information devices. The keypad method used in mobile phones is inconvenient because the input speed is often slow and mistyped.
In order to input letters, numbers or symbols at a higher speed in the above-described information devices such as PCs, laptops, PDAs or mobile phones, so-called 1 operation 1 phoneme input is performed in which one phoneme (character) is input in one input operation. There is a need.
In the case where the operation 1 phoneme input is for Korean, the buttons or input keys for inputting 24 or more characters need to be arranged in the information apparatus.
If the target language is English, Japanese, or other foreign languages, more buttons or input keys may need to be added than in Korean.
However, the conventional input device used in various information devices is a method of assigning a character to each input key and tapping or pressing with a finger to input.
Therefore, in a personal portable information terminal such as a mobile phone having a relatively small space for arranging the input keys, it is difficult to arrange more than 24 input keys having the size of a finger. This has been the reason why keyboards have never been miniaturized so far.
In order to solve this problem, in Korean Patent Application No. 10-2008-0029651 (hereinafter referred to as 'prior art') previously filed by the inventor of the present application, the first direction input and the second direction input are connected to one input unit. By simultaneously or sequentially performing, a character input device capable of maximizing the number of characters that can be input in one operation in a minimum input space and simultaneously inputting one or more phonemes in one operation has been developed.
That is, as shown in Fig. 1 and 2, the character input device 1 according to the prior art, the
In the prior art, when the first direction indicating positions M 1 , M 2 ,... And the second direction indicating positions P 1 , P 2 , ... are provided in eight or more places, each indicating position If the interval between the two is narrowed and the correct movement or pressing is not performed to the desired indication position, there is a problem that a character other than the desired character is input. This is particularly the case when a user inputs a character while looking at the display window 4 on which a character input from the input unit is displayed without looking at the
Moreover, since it is difficult to accurately detect each instruction position and the size of the character input device 1 is narrow enough to place one finger, the two assigned to the adjacent instruction positions when performing the direction input to any one instruction position. It may also occur when two characters are selected at the same time.
Accordingly, an object of the present invention is that the first direction indicating position and the second direction in a state in which the input portion is formed to be recessed and the finger is inserted into the input portion so as to be in contact with both the first direction indication position and the second direction indication position provided in a plurality of radial directions. The present invention provides a character input device capable of distinguishing an input direction by a tactile sense in which interference does not occur when inputting directions to each indication position by providing a tactile utilization structure capable of inputting the indication positions separately from each other.
According to a feature of the present invention for achieving the above object, the first invention relates to a character input device capable of distinguishing the input direction by the touch, the base; A first direction input configured to be recessed in a size such that all or a portion of the fingertips can be inserted into the base, and press any one of a plurality of first direction indicating positions provided to be in contact with the periphery of the inserted finger; An input unit configured to independently perform second direction input for pressing any one of a plurality of second direction indication positions provided to be in contact with a finger separately from the first direction indication position; A first sensing unit provided at each of the first direction indicating positions to sense the first direction input; A second sensing unit provided at each of the second direction indicating positions to sense the second direction input; And when the first direction input is detected by the first sensing unit, the first character assigned to the first direction indicating position where the first direction input is performed or when the second direction input is detected by the second sensing unit.

According to a third aspect of the present invention, at least one of the first direction indication position and the second direction indication position in the input unit is characterized in that a protrusion is formed to protrude so that an input direction can be detected by touching a finger. .
In this case, the protrusion may be formed at each of the first direction indicating position and the second direction indicating position, and the first direction indicating position or the first direction indicating position which is judged to be easy to distinguish each of the first direction indicating position and the second direction indicating position. It may be formed only in the two-direction indication position. Among them, the following embodiments of the present invention illustrate a case where the first direction indicating position and the second direction indicating position are formed respectively.

The third character is input instead of the second character corresponding to the direction input.
In the sixth invention, in the sixth invention, the third character is a case where the second direction input is performed after the first direction input is performed first, and the first direction input after the second direction input is performed first. In this case it is characterized in that it is set differently.
Therefore, if the third character is changed according to the execution order of the first direction input and the second direction input, the number of characters that can be input by the combination input through the first direction input and the second direction input is doubled, so This can be useful for increasing the number of possible characters.
