Abstract

A user interface for a text entry device, comprising: a display having a first display section and a second display section, and a keypad including a set of text entry keys each having a set of characters associated therewith. The set of characters associated with each of the text entry keys being displayed in the second display section. A predictive character editor engine with associated directories is adapted to receive a string of input strokes and to output a list of matching word candidates in response thereto. A controller receives inputs from a set of text entry keys, and generates said string of input strokes for the predictive character editor. The controller presents in said first display section at least one of said matching word candidates from the predictive character editor for selection by the user.

Claims

1. A user interface for a text entry device, comprising:

a display having a first display section and a second display section;

a keypad including a set of text entry keys each having a set of characters associated therewith;

said set of characters associated with each of text entry keys being displayed in the second display section;

a predictive character editor engine with associated directories and adapted to receive a string of input strokes and to output a list of matching word candidates in response thereto;

a controller receiving inputs from set of text entry keys, and to generate said string of input strokes for the predictive editor, and the controller presents in said first display section at least one of said matching word candidates from the predictive editor for selection by the user.

2. A user interface according to claim 1, wherein character ranges for the text entry keys are displayed together with icons for the associated text entry keys in the second display section.

3. A user interface according to claim 2, wherein four navigation keys for moving cursor means in the display act as text entry keys in a text entry mode.

5. A communication terminal according to claim 1, wherein character ranges for the text entry keys are displayed together with icons for the associated text entry keys in the second display section.

6. A communication terminal according to claim 2, wherein four navigation keys for moving cursor means in the display act as text entry keys in a text entry mode.

4. A communication terminal having a user interface comprising:

a display having a first display section and a second display section;

a keypad including a set of text entry keys each having a set of characters associated therewith;

said set of characters associated with each of text entry keys being displayed in the second display section;

a predictive character editor engine with associated directories and adapted to receive a string of input strokes and to output a list of matching word candidates in response thereto;

a controller receiving inputs from set of text entry keys, and generating said string of input strokes for the predictive character editor, and the controller presents in said first display section at least one of said matching word candidates from the predictive character editor engine for selection by the user.

7. A method of handling a user interface for a communication terminal, and comprising steps of:

displaying in the second display section of the display sets of characters associated with each of text entry keys;

pressing at least one of a set of text entry keys each having a set of characters associated therewith;

generating a presentation of the string of input strokes and forwarding this presentation to a predictive editor engine with associated directories;

said predictive editor engine outputs a list of matching word candidates in response to a received presentation; and

presenting in a first display section of the display at least one of said matching word candidates from the predictive character editor engine for selection by the user.

8. A method according to claim 7, wherein character ranges for the text entry keys are displayed together with icons for the associated text entry keys in the second display section.

9. A method according to claim 8, wherein four navigation keys for moving cursor means in the display act as text entry keys in a text entry mode.
