Various techniques for autocorrecting virtual keyboard input for various languages (e.g., Japanese, Chinese) are disclosed. In one aspect, a system or process receives a sequence of keyboard events representing keystrokes on a virtual keyboard. A hierarchical data structure is traversed according to the sequence of keyboard events to determine candidate words for the sequence of keyboard events. A word lattice is constructed using a language model, including deriving weights or paths in the word lattice based on candidate word statistics and data from a keyboard error model. The word lattice is searched to determine one or more candidate sentences comprising candidate words based on the path weights. Paths through the word lattice can be pruned (e.g., discarded) to reduce the size and search time of the word lattice.

Autocorrecting language input for virtual keyboards

Text input is corrected on a touch-sensitive display by presenting a list of candidate words in the interface which can be selected by touch input. The candidate list can include candidate words having two or more character types (e.g., Roman, kana, kanji). In one aspect, the candidate list can be scrolled using a finger gesture. When a user's finger traverses a candidate word and the touch is released, the candidate word is inserted into a document being edited. In another aspect, characters can be erased by touching a key (e.g., a backspace or delete key) and making a sliding, swiping, or other finger gesture. A number of characters proportional to a distance (e.g., a linear distance) of the finger gesture across the display are erased. If there are characters in a text input area, those characters are erased first, followed by characters in the document being edited.

Input methods for device having multi-language environment

Methods, systems, and apparatus, including computer program products, for inputting text. A virtual keyboard is presented in a first region of a touch sensitive display of a device. An input representing a phonetic string is received on the virtual keyboard. The entered phonetic string is presented in a second region of the touch sensitive display. One or more candidates are identified based on the phonetic string. At least a subset of the candidates is presented. An input selecting one of the candidates is received. The entered phonetic string is replaced with the selected candidate.

Language input interface on a device

Methods, systems, devices, and apparatus, including computer program products, for inputting text. A user interface element is presented on a touch-sensitive display of a device. The user interface element is associated with a plurality of characters, at least a subset of which is associated with respective gestures. A user input performing a gesture with respect to the user interface element is received. The character from the subset that is associated with the gesture performed with respect to the user interface element is inputted.

Methods for converting a source character string to a target character string are described herein. In one aspect of the invention, an exemplary method includes receiving a first character string having the source character string, dividing the first character string into a plurality of sub-strings, converting the plurality of the sub-strings to second character strings through a dictionary, creating third character strings corresponding to the plurality of the sub-strings, analyzing the second and third character strings, constructing fourth character strings from the second and third character strings based on the analysis, creating a candidate list based on the fourth character strings, selecting the target character string from the candidate list and outputting the target character string. Other methods and apparatuses are also described.

Japanese virtual dictionary

A method, apparatus, system, and signal-bearing medium that converts input data, such as speech or phonetic characters, to text by finding documents that are similar to the input data and using the similar documents to create a customized dictionary including a weighted list of words found in the similar documents. The words that are weighted higher may have a higher probability of being used in the input data, so words in the converted text are chosen based on the weighted list. A vector space model may be used to search for the similar documents.

Adaptive context sensitive analysis

A computer operating system Text Services Manager (TSM) operates as an interface between an application and a selection of text services, enabling the user to efficiently select from among a variety of text services without regard to the specific protocol requirements of the application. The TSM architecture consists of an application program which receives user input through the input event manager of the operating system toolbox routine. The TSM receives the user input event and controls the transmission of the event to a component manager for redirection to a specific text services component, based on the instructions of the TSM. The text services component processes the input method and returns the processed input to the TSM, where the TSM directs the generation of an appropriate protocol for return of the processed input event to the application.

Text services manager

A Text Services Manager (TSM) maintains and uses TSM documents to ensure proper communication between applications and their needed input methods. A TSM document comprises information about the input methods and text services used by a particular instance of an application. One TSM document is preferably associated with each working document represented by an application window. Through use of the TSM document, the TSM provides for multiple instances of a particular input method, and the automatic synchronization of the input method to the active window. The preferred embodiment of the present invention comprises novel methods that provide this functionality including: methods for opening or closing a TSM aware application, methods for creating and disposing of TSM documents, and methods for activating and deactivating a TSM document.
