    摘要: 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.

    摘要: A touchpad device is to be operated by using a stylus pen, and includes a touchpad and a controller that are connected to each other. The controller is connected to an electronic device that includes a display panel, and operates in a stylus-pen mode where a handwriting area is presented on the display panel. When it is determined that a distance between the stylus pen and the touchpad is less than a preset pen-hover distance but is non-zero, the controller operates in a hover-move sub-mode where the controller outputs a control signal to enable the electronic device to present, in the handwriting area, the cursor moving, without presenting a trace of the cursor.

    摘要: Constrained stroke editing techniques for digital content are described. In these examples, a stroke constraint system is employed as part of a digital content creation system to manage input, editing, and erasure (i.e., removal) of strokes via a user interface as part of editing digital content. To do so, locations and attributes of a displayed stroke are used to constrain location and/or attributes of an input stroke.
