DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device, and more particularly to a character input operation.

[0002]

2. Description of the Related Art
In a mobile phone, a name is input to an address book by operating ten keys (numerical keys of 0 to 9). In addition, the use frequency of such a character input operation tends to increase with the spread of a character mail service and the like.

A conventional character input operation is as follows. The numeric keys correspond to the Japanese lines A to W, respectively. When one key is pressed in the character input mode,
"A" is displayed. In addition, for example, to input "e", the user presses the 1 key of the line four times to input and display.
In other words, every time you press the 1 key, “A → I → U → E → O”
And the display switches.

However, in the above input operation, for example, when "e" is input, the 0 key must be short-pressed four times, and the input is troublesome and the operability is poor.

Therefore, as an inputting method, it is conceivable to have a 10 × 10 map like a pager (registered trademark), for example. For example, if one key is pressed twice, "A" is displayed when the key is operated in the order of 1 or 3, the number of key operations is reduced, and the operability is improved.

However, in such a pager type input method, if the above-mentioned map is not stored in the user's head, there is a problem that it is rather difficult to use and is apt to be mistaken.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a communication terminal device capable of reducing the number of times of character input operation and performing reliable character input.

[0008]

In order to achieve the above object, according to the first to third aspects of the present invention, a character map of A rows × B columns corresponding to the A rows to the W rows is stored.
The character input function is such that one of the character keys corresponding to the keys A and B is pressed once to set one character input candidate in the character map. At the time of input operation, a guide display is provided to allow the user to visually recognize which of the numeric keys corresponds to the character input candidate.
Operate any one of the keys to
If you select one of them, the above display will correspond to this key
Display of the five characters on the predetermined line and the five characters

It is characterized by.

[0009] Thus, the character input function is designed to set one character input candidate in the character map by pressing each of the keys corresponding to A and B of the numeric keypad once. In addition, the number of key operations for character input operation can be reduced as compared with the related art.

[0010] In addition, a guide display is provided to allow the user to visually recognize which character input candidate corresponds to the numeric keypad during the character input operation, so that the user can reliably store the character map without storing it. In this case, the user can input characters, and the operability can be improved.

The specific structure of the invention described in claim 1 is preferably configured as described in claims 2 and 3 .

In the invention according to claim 3 , the numeric keypad is provided with a touch sensor for detecting whether or not the key is touched by a user's operation. It is characterized in that a character line corresponding to the key and a character input candidate among them are uttered by voice.

[0013] In addition to this, in addition to these, the character to be touched guides which character line or character corresponds to the voice, so that the visually impaired person can easily input the character.
