Abstract: To enter Chinese text, a user enters the corresponding phonetic spelling via telephone style keypad. Some or all keys represent multiple phonetic letters. In disambiguating entered key presses to yield a valid phonetic spelling, a computer divides the key presses into segments, while still preserving key press order. Each segment must correspond to an entry in a dictionary of Chinese characters, character phrases, and/or character components such as radicals or other predetermined stroke groupings. Upon arrival of a new key press that cannot form a valid entry when appended to the current segment, key presses are incrementally reallocated from the previous segment. As for already-resolved segments occurring prior to the previous and current segments, these are left intact. After each shifting attempt, the computer reinterprets key presses of the last two segments, and accepts the new segmentation if the segments form valid dictionary entries.

Abstract: A system and method for inputting Chinese characters using Pinyin without requiring the entry of a delimiter key between Pinyin entries in a reduced keyboard is disclosed. The system searches for all possible single or multiple Pinyin spellings based on the entered Latin alphabets. Once the user has completed the inputting of the Pinyin spellings for desired Chinese phrase or characters, all possible matching phrases or characters are displayed on screen and off-screen due to screen size. The user then scrolls through a list of matching phrases or characters and selects the desired one by clicking.

Abstract: A computer-driven system includes different modes interpreting user entered text according to different corresponding vocabularies. Each mode may additionally include a different modality for ultimately resolving and completing the input. Each mode presents the user with a different interpretation of user entered text, according to the associated vocabulary. Displayed output is limited to one or another of the modes in accordance with user instructions to switch between modes.
