A user interface () of a portable electronic device () includes a plurality of keys (). The user interface () includes a first group of keys representing vowel characters (), and a second group of keys representing consonant characters (). The second group of keys is separate from the first group of keys. For the first group of keys, a first key represents leading vowels (), a second key represents above and below vowels (), and a third key represents following vowels (). The second group of keys may be subdivided into phonetic consonant groups (FIGS.&) or alphabetic consonant groups (FIGS.&).

User interface of a keypad entry system for character input

A graphical handwriting recognition user interface includes a display, one or more areas designated on said display for enabling entry of handwritten information using a stylus, and an image of a character being displayed within the one or more areas designated for entering the handwritten information, the image depicting a form of the handwritten information to be entered. The image of the character is displayed for a predetermined period of time. The image of the character is displayed on the display using a low contrast ratio, and is displayed on the display in a manner depicting the character being entered, thereby rendering animation to the image of the character being displayed.

Graphical handwriting recognition user interface

A data entry apparatus (,) receives a first character key from a keypad (,). A set of characters associated with the first character key is displayed. A second character key from the keypad (,) is received, wherein a second set of characters is associated with the second character key. A character from the first set of characters is combined with a character from the second set of characters. A set of alternative n-grams is displayed, derived from the step of combining, in descending order based on a probability of frequency of use in a given language. When an alternative n-gram is detected as being actively highlighted, the n-gram is locked to create a locked n-gram and characters associated with subsequent character keys vary in their combinations with respect to the locked n-gram.
