Description

Mini keyboard {MINI KEYBOARD}

The keyboard we use today is not only bulky and space-intensive with at least 100 input keys, but also large and heavy when moving. Also, nowadays, due to the development of various input devices, unlike the past, the input keys are not used much, and the special keys are mainly replaced by the mouse. In addition, text input is recognized by a scanner or a voice, and the technology is developing day by day. However, it still uses an existing keyboard as its input device.

In particular, laptops take up about 1/2 of the size of a laptop, and the bulkiness and weight of the laptop are inconvenient for moving, and in the case of a set-top box, the keyboard is inconvenient.

In order to solve the problems as presented in the related art, the number of input keys of the keyboard is reduced to 40 or less, and the size of the TV remote control is also convenient to carry, and the keyboard functions like all the functions of the existing keyboard. It can be used.

In addition, the keyboard itself can be embedded to eliminate the need for a separate mouse.

누르면 Press the Enter key twice. ㅑ is displayed.

Pressing Shift + ㅏ ㅑㄲ enter key displays ㄲ.

The following English letter input method displays all English letters by combining alphabets as shown in [Table 3] below.

TABLE 3

Characteristic of the above input method, as shown in Table 3, 26 letters of the alphabet can be assigned to 12 input keys 2-3 each time to press the Shift key and then press the input key to select the alphabet.

For example

ＶＷＸ In case of input key, press ＶＷＸ input key once to display Ｖ character.

Press Shift + ＶＷＸ to display the letter 되고

Pressing Shift + Shift + 된다 displays the letter Ｘ.

Alternatively, the 26 letters of the alphabet are assigned to 12 input keys, each of 2-3 letters, to be pressed repeatedly. When the character is input, 3 seconds after the character is entered, the cursor automatically moves to the next cell.

Next, the English letter inputs all alphabetic characters by combining alphabets as shown in [Table 4].

TABLE 4

Characteristic of the above input method, as shown in [Table 4], 26 letters of the alphabet can be assigned to 12 input keys of the same stroke order 2-3 each by pressing the Shift key and then press the input key to select the alphabet.

For example

ＶＷＹ In case of input key, press ＶＷＹ input key once to display Ｖ character.

Press Shift + ＶＷＹ to display the letter 되고

Pressing Shift + Shift + 된다 displays the letter Ｙ.

Alternatively, the 26 letters of the alphabet are assigned to 12 input keys with the same stroke order 2-3 times each time, and the cursor is automatically moved to the next space after 3 seconds of character input.
