Abstract: A computing device outputs, for display, a virtual keyboard comprising a plurality of virtual keys. Furthermore, the computing device receives an indication of a first movement of an input object along a spatial path. The computing device determines, based on locations of the virtual keys and locations along the spatial path, a plurality of character strings. In response to determining that the first movement has ceased for at least a threshold amount of time, the computing device outputs, for display, the plurality of character strings. While the character strings are displayed, the computing device receives an indication of a second movement of the input object. The computing device selects, in response to the indication of the second movement, and based at least in part on a direction of the second movement of the input object, a particular character string from the plurality of character strings.

Abstract: A computing device determines, based at least in part on indications of user input, scores for a first set of candidate strings and a second set of candidate strings. Each candidate string from the first set of candidate strings is in a lexicon. Candidate strings from the second set of candidate strings are not necessarily in the lexicon. The computing device determines the scores for the first set of candidate strings based on probabilities of the candidate strings being entered. For each candidate string from the second set of candidate strings, the computing device determines the scores for the candidate string based on probabilities of characters of the candidate string being entered. The computing device selects a candidate string based on the scores for the first and second sets of candidate strings and outputs, for display at the display device, the selected candidate string.

Abstract: A computing device is described that outputs for display at a presence-sensitive screen, a graphical keyboard having keys. The computing device receives an indication of a selection of one or more of the keys. Based on the selection the computing device determines a character string from which the computing device determines one or more candidate words. Based at least in part on the candidate words and a plurality of features, the computing device determines a spelling probability that the character string represents an incorrect spelling of at least one candidate word. The plurality of features includes a spatial model probability associated with at least one of the candidate words. If the spelling probability satisfies a threshold, the computing device outputs for display the at least one candidate word.

Abstract: Techniques are described for character deletion on a computing device that utilizes a gesture-based keyboard. The computing device includes a processor and at least one module operable by the processor to output, for display at a presence-sensitive display, a graphical keyboard comprising a plurality of keys and a text editor field. In response to receiving an indication of a gesture that comprises a first path, the module outputs a first character, based at least in part on the first path, associated with a first key and a second character associated with a second key. In response to determining that the gesture further comprises a second path that retraces at least a portion of the first path, the module removes the second character from the text editor field of the presence-sensitive display.
