Abstract: Pen input received by a computing device may first be evaluated to determine an associated intent. For example, it may be determined whether it is intended to be handwriting input, in which case the pen input may be intercepted (e.g., rather than provided to an underlying application for further processing). Subsequently, a target determination is made, where the pen input is processed to determine which input field should receive the input. When the pen input is processed to generate handwriting input, context associated with a determined input field may be used to improve recognition accuracy. Finally, various techniques may be used to ultimately provide the handwriting input to the determined input field, for example according to the set of capabilities that is supported by an application associated with the input field. Similarly, aspects of the disclosed system may be disabled or adapted when the application does not support such functionality.
