Abstract
A system and method for efficient Asian character text input into a reduced keypad machine such as a word processor, telephone, hand-held computer, or personal computer is provided. The system comprises a data entry keypad associated with a monitor, and a disambiguation process supporting multiple keycap depression timespan range definitions and interpretations to produce accurate messaging with a reduced keypad.
Claims26
A text input system comprising:
- a user input device having a plurality of user-actuable keys, each said key being associated with at least one character element of an Asian language character, each said key also being actuable for a variable timespan range;
- and
- a keypress interpretation process for determining the duration of the variable timespan range and comparing said duration to a plurality of timespan ranges, at least one of which represents a character element selection by a user, another of which represents a candidate selection by said user.
A wireless telephone system for text input comprising:
- a user input device having a plurality of user-actuable keys, each said key being associated with at least one character element of an Asian language character, each said key also being actuable for a variable timespan range;
- and
- a keypress interpretation process for determining the duration of the variable timespan range and comparing said duration to a plurality of timespan ranges, at least one of which represents a character element selection by a user, another of which represents a candidate selection.
A method for processing electronic entry of text comprising:
- receiving user input into a front end process, said front end process interfacing with a user input device, said user input device having at least one user-actuable key, said key being actuable for a variable timespan range;
- determining the duration of the variable timespan range;
- and
- comparing said duration to a plurality of minimum timespan ranges, at least one of which represents a character element selection, another of which represents a candidate selection.
