Description

Apparatus and Method for inputting Character}

The present invention relates to a text input apparatus and method, and more particularly, to a text input apparatus and method applicable to a virtual keyboard provided in a mobile terminal.

In general, the use of media through mobile devices centered on smartphones is steadily increasing. In the case of smartphones, the penetration rate recorded 84.8% in November 2017, and in October 2018, the number of smartphone subscribers exceeded 50 million, effectively opening the era of one smartphone per person. was expanded to Smartphone operating systems include Android, iOS, Windows Mobile, Symbian, etc. In Korea, as of November 2017, Android has a 77.4% share.

The types of apps running on smartphones are very diverse, such as messengers, portals, news, games, entertainment, and life services such as maps, banking, and financial payments using credit cards or coupons.

In all other methods except for fingerprint recognition, passwords and other secret information must be entered through the keyboard. Since a smartphone does not use a real keyboard, a virtual keyboard is provided on the screen. Compared to a general PC, the screen size is small and multi-window is not supported, so there are significant restrictions on the security of keyboard input.

In addition, many services provided in the PC are supported in the form of smartphone apps. However, in exchange for the convenience of portability and portability that smartphones provide, they have to pay the price of various limitations and vulnerabilities due to low performance and small screen.

Most apps running on smartphones provide dynamic virtual keyboards similar to PCs to receive information.

On the other hand, in the case of the smartphone banking app, unlike the PC, the size of the window cannot be enlarged, reduced, or the position of the window cannot be moved, and the position and size of the virtual keyboard are fixed without providing a horizontal view (screen rotation). The risk of exposure to PC is higher than in the case of PC.

In order to alleviate this risk, an app according to the prior art provides a 'rearrangement key' so that the position of a blank space is changed when it is pressed. In addition, the size of the inserted blank is reduced to 1/2 of the actual key and the number is doubled to improve safety, and the number of inserted 1/2 blanks is reduced and the size of the keys is slightly increased.

As described above, for the convenience of the user, the method of rearranging the keys is limitedly applied, and instead of rearranging the positions of the keys, one or two blanks are inserted for each line so that the keys can be located in different places each time. Therefore, the row to which each key belongs is fixed, and the relative position of the keys in each row does not change.

However, according to the prior art, if the rearrangement key is not pressed, the position of the blank is fixed, and the duplicate key included in the password is input at the same position and the distribution is exposed, or the distribution of the position where the blank can come is uniform Since the relative position of the key does not change, the difference between the probability of a blank on the left and the probability of a blank on the right of the keys close to the left and right ends increases, as a result, compared to the keys in the middle, The identification rate of the key is increased, and since the user does not enter a blank space, when the password key is input from the leftmost or rightmost side, there is a security vulnerability in which the identification rate reaches 100%.

In particular, the current mobile keyboard consists of about 25 keys.

Mobile phone keyboards developed and used so far have to press a few times to enter Hangul (first consonant, middle consonant, final consonant) and special characters, which corrects error input and is inconvenient. In addition, the layout of the keyboard is different for each mobile phone manufacturer to find the corresponding letter because it does not match the grammar (in alphabetical order..ABC order), so it is especially difficult for infants, housewives, and the elderly to use it.
