Device for input character of cellular phone and method for as the same}
[12] The present invention relates to a character input device and method for a mobile communication terminal, and more particularly, to an English character and Russian character input device and method through a shortcut keypad of a mobile communication terminal such as PCS, PDA, IMT200, two-way remote control.
[13] Recently, with the introduction of digital cell phone service, various information terminals that need to send and receive text along with text service through the phone have been developed, and various methods have been developed to try to enter text using only the keyboard of the phone, not the computer keyboard. As information and communication devices become smaller, the number of input buttons decreases. However, as the function is improved in inverse proportion to the reduction in size, the necessity of inputting characters continues to increase.
[14] For example, a mobile phone, which is a small, generalized product using a Korean input device, is described as an example. Since a character input key of a mobile phone is used in a limited number, it is necessary to assign several characters to a single button. To select one letter by pressing the button as many times as necessary and then to move to the next space with the cursor movement key, and then select the next letter in the same way. This method is very inconvenient because the user does not input the characters but combines the characters one by one, making it difficult to input a large amount of characters because the input method is difficult, and it is not possible to input characters continuously. This is very uncomfortable.
[15] Accordingly, an object of the present invention is to assign a plurality of characters to the numeric keys arranged in the mobile communication terminal for fast character input during character input, any of the characters assigned to the numeric key corresponding to the character input signal of the corresponding numeric key The present invention provides a character input device and method for a mobile communication terminal configured to display one character by additional input of a symbol key and a numeric key.
