1. An apparatus for text entry comprising:
- a directional user input device having a plurality of motions, some of which are associated with stroke input signals representing P predefined stroke categories;
a processor coupled to said directional user input device;
at least one memory coupled to said processor, said at least one memory containing at least one database and at least one program used by said processor to process data, said at least one database comprising a number of characters and data of stroke order commonly used for writing of each of the characters as well as data of use frequency associated with each of the characters, said stroke order based on said predefined stroke categories; and
an output member coupled to said processor, said output member comprising a text display area and a selection list display area;
wherein said at least one program causes said processor, for each stroke input signal associated with an input motion, to;
identify which one of said stroke categories is represented by said stroke input signal;
display a selection list, said selection list comprising a number of most frequently used characters that start with said identified stroke categories;
concurrently with a stroke input signal being identified, display a numeric or iconic representation of the stroke represented by said stroke input signal until the user chooses to enter any character from said selection list, at which point display said entered character in said text display area; and
repeat the process for entering a next character.

Abstract
A Chinese text entry system and method is provided to allow users to enter a character to a device such as a cellular phone or a PDA by adding a first few strokes required for the character using a joystick or its equivalent. By simply moving the joystick to add one or more strokes which are used to start writing a character, or in some case even before any stroke is added, a user can find a desired character from a displayed selection list. The selection list is context sensitive, varying depending on the last character entered, so that the user can be provided with the most possible candidates of the desired character.

17. A method for text entry comprising the steps of:
-
identifying a stroke input signal representative of one of five predefined stroke categories, said stroke input signal being associated with a predefined motion of a directional user input device coupled to a processor which is further coupled to a database and a display device; as soon as a first stroke for a character is identified, displaying a first selection list in a selection list display area of the display device, said first selection list comprising ten most frequently used characters that start with said first stroke; if the user chooses to enter any character from said first selection list, displaying said chosen character in a text display area of the display device;
otherwise,displaying a second selection list when a second stroke is identified, said second selection list comprising ten most frequently used characters that start with said first stroke followed by said second stroke; if the user chooses to enter any character from said second selection list, displaying said chosen character in said text display area;
otherwise,displaying a third selection list when a third stroke is identified, said third selection list comprising ten most frequently used characters that start with said first stroke followed by said second stroke and then followed by said third stroke; if the user chooses to enter any character in said third selection list, displaying said chosen character in said text display area;
otherwise,continuing to display a next selection list corresponding to a next stroke added until the user chooses to enter any character from said next selection list; concurrently with a stroke input signal being identified, display a numeric or iconic representation of the stroke represented by said stroke input signal; and repeating above steps for entering a next character. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A computer readable medium encoded with computer executable instructions for carrying out a process for Chinese text entry, said process comprising the steps of:
-
identifying a stroke input signal representative of one of five predefined stroke categories, said stroke input signal being associated with a predefined motion of a directional user input device coupled to a processor which is further coupled to a database and a display device; as soon as a first stroke for a character is identified, displaying a first selection list in a selection list display area of the display device, said first selection list comprising ten most frequently used characters that start with said first stroke; if the user chooses to enter any character from said first selection list, displaying said chosen character in a text display area of the display device;
otherwise,displaying a second selection list when a second stroke is identified, said second selection list comprising ten most frequently used characters that start with said first stroke followed by said second stroke; if the user chooses to enter any character from said second selection list, displaying said chosen character in said text display area;
otherwise,displaying a third selection list when a third stroke is identified, said third selection list comprising ten most frequently used characters that start with said first stroke followed by said second stroke and then followed by said third stroke; if the user chooses to enter any character in said third selection list, displaying said chosen character in said text display area;
otherwise,continuing to display a next selection list corresponding to a next stroke added until the user chooses to enter any character from said next selection list; concurrently with a stroke input signal being identified, display a numeric or iconic representation of the stroke represented by said stroke input signal; and repeating above steps for entering a next character. - View Dependent Claims (25, 26, 27, 28, 29, 30)
