Electronic device for controlling deletion of character input on character input screen, character input control method for controlling deletion of character input on character input screen, and storage medium storing therein character input control method program
First Claim
1. A character input control method comprising:
- detecting a character input key being pressed, and in response to the detection of a character input key being pressed, displaying a character corresponding to the character input key at a position of a cursor displayed on a character input screen;
selecting a deletion mode; and
detecting a single press on a character delete key, and in response to detecting a single press on a character delete key, deleting at least one character displayed on the character input screen,wherein the displaying a character corresponding to the character input key includes;
upon detecting the character input key being pressed, displaying the character corresponding to the character input key as an unconfirmed character on the character input screen, the unconfirmed character being a character input of which is to be confirmed when a confirmation key is pressed;
acquiring and unconfirmed character or a character string of unconfirmed characters displayed on the character input screen;
determining that the unconfirmed character or the character string is not a candidate for any word registered in the word table; and
in response to determining that the unconfirmed character or the character string is not a candidate for any word registered in the word table, acquiring a character input through a character input key just before the determination and storing in storage an unconfirmed character that makes word prediction impossible the acquired character as a deletion start character,the deleting at least one character includes;
deleting the at least one character in a first deletion mode in which the deletion start character is deleted or the deletion start character and at least one unconfirmed character immediately preceding or following the deletion start character are deleted;
deleting the at least one character in a second deletion mode in which all unconfirmed characters are deleted;
deleting the at least one character in a third deletion mode in which a designated number of characters immediately preceding or following the cursor are deleted; and
deleting the at least one character in a fourth deletion mode in which only one character immediately preceding or following the cursor is deleted, andthe selecting a deletion mode includes selecting one of the first through fourth deletion modes.

Abstract
An electronic device includes a display, an input device, and a controller. The display displays a character input screen. The input device includes character input keys, a character delete key, and a confirmation key. When the controller detects a character input key being pressed, the controller causes a character corresponding to the character input key to be displayed on the character input screen and determines whether or not any word registered in a word table is predictable from an unconfirmed character or a character string of unconfirmed characters input of which has not been confirmed through the confirmation key. In response to a single press on the character delete key, the controller deletes a deletion start character that makes word prediction impossible, or the deletion start character and at least one unconfirmed character immediately preceding or following the deletion start character.

8. An electronic device comprising:
-
a display configured to display a character input screen; an input device including operation keys; storage storing therein a word table in which a plurality of words are registered; and a controller configured to detect each of the operation keys being pressed, wherein at least one character and a cursor are displayed on the character input screen, the operation keys include character input keys, a character delete key for deleting any of the at least one character, and a confirmation key for confirming input of the at least one character, each of the at least one character being input through one of the character input keys, when the controller detects any of the character input keys being pressed, the controller causes a character corresponding to the pressed character input key to be displayed as an unconfirmed character on the character input screen, the unconfirmed character being a character input of which is to be confirmed when the confirmation key is pressed, and the controller determines whether or not an unconfirmed character or a character string of unconfirmed characters that is displayed on the character input screen is a candidate for any word registered in the word table, when determining that the unconfirmed character or the character string of the unconfirmed characters is not a candidate for any word registered in the word table, the controller acquires a character input through one of the character input keys just before the determination, the controller stores in the storage the acquired character as a deletion start character, the controller has a first deletion mode, a second deletion mode, a third deletion mode, and a fourth deletion mode, each as a deletion mode in which at least one character displayed on the character input screen is deleted in response to a single press on the character delete key, in the first deletion mode, the controller deletes the deletion start character, or the deletion start character and at least one unconfirmed character immediately preceding or following the deletion start character, in the second deletion mode, the controller deletes all unconfirmed characters, in the third deletion mode, the controller deletes a designated number of characters immediately preceding or following the cursor, in the fourth deletion mode, the controller deletes only one character immediately preceding or following the cursor, and the controller selects one of the first through fourth deletion modes. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
