Abstract:
1. A language model back-off system for use with a user interface employing one or more language models to constrain navigation of selectable user interface input components representing a set of characters based on at least one previously received user interface input component, the system comprising: a user input interpretation module receiving user input and interpreting the user input to determine if a selection is made of one or more user interface input components, wherein said user input interpretation module, if a selection is not made, determines whether conditions are met for replacing at least one of the one or more language models employed to constrain navigation of the user interface input components with a replacement language model, wherein the replacement language model defines a set of selectable user interface components that is different than the set of user interface components defined by the one or more language models that are to be replaced; and a language model back-off module replacing at least one of the one or more language models with the replacement language models if the conditions are met, further comprising a user interface displaying the user interface input components with a focus indicator, the focus indicator operable to visually differentiate between selectable user interface input components and non-selectable user interface input components pursuant to the one or more employed language models.
