HANDHELD ELECTRONIC DEVICE WITH TEXT DISAMBIGUATION

摘要

A handheld electronic device with a reduced QWERTY keyboard and disambiguation software. The device outputs a default output and a number of variants. The output is based largely upon the likelihood that a user intended a particular output, but various features of the device provide additional variants provided by various logic structures resident on the device. The device enables editing during text entry and provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. If a field into which text is being entered is determined to be a special input field, a disambiguated result can be sought first from a predetermined data source prior to seeking results from other data sources on the device.
