Problems solved by technology

[0004] However, such traditional methods of using arrow keys to enter characters via an on-screen keyboard may suffer from the requirement to select a relatively large number of arrow keys for entering a single word, and considerable input errors may occur, especially when The input of a word involves pressing the character keys of the on-screen keyboard that are far apart from each other
In addition, in the conventional method, it generally takes a considerable amount of time to input characters, and the input of characters is complicated and inconvenient

Embodiment Construction

[0022] image 3 is a diagram of a key arrangement of an apparatus for inputting characters according to an exemplary embodiment of the present invention. see image 3 , 26 alphabetic characters are divided into first to fourth groups, and 4 direction keys are assigned to the first to fourth groups, respectively. In detail, the up key is assigned to the first group, the down key is assigned to the second group, the left key is assigned to the third group, and the right key is assigned to the fourth group. Accordingly, alphabetic characters can be input by pressing the direction keys assigned to the corresponding groups. In this way, the number of keystrokes required to enter a series of characters can be reduced. The division of alphabetic characters can be performed in various ways. For example, the groupings may be organized according to how frequently alphabetic characters typically occur.

[0023] After selecting one of the alphabetic characters using the direction key...

Abstract

An apparatus and method for inputting characters in which one of a plurality of characters can be chosen operate by using directional keys. The plurality of characters are classified into a predetermined number of groups and the directional keys are respectively allocated to the groups. Accordingly, when a user presses one of the directional keys, the characters belonging to the group to which the directional key pressed by the user is allocated can be sequentially chosen by sequentially pressing the directional key.

Description

technical field [0001] An apparatus and method according to the present invention relate to inputting characters, in particular to inputting characters in which one of a plurality of characters can be selected by using direction keys. Background technique [0002] In recent years, functions of electronic devices have been increasingly diversified, and thus, more and more electronic devices capable of providing functions not provided by previously existing electronic devices have been developed. For example, a television is no longer just a tool for watching broadcast programs, but also a tool for accessing and obtaining data over the Internet. As the functions provided by electronic devices have diversified, the data that users need to input into such electronic devices has also diversified. However, placing all the keys of a keyboard on a small device such as a remote control or a mobile phone has significant limitations. Therefore, an on-screen keyboard technology has be...
