    摘要： Stylus “focus” designates or establishes an element or area of a computer interface to receive input (e.g., such as electronic ink). Focus may be used, for example, to prepare the associated element to receive input by “waking” the system from a “stand-by” mode; by triggering increased digitizer polling frequency; by setting up data structures or allocating memory resources to receive input; retrieving data relating to the input or characteristics thereof, etc. Systems, methods, and computer-readable media for managing stylus focus may include: (a) receiving input indicating that a stylus is located proximate a digitizer; and (b) providing focus to a control element corresponding to the stylus location, e.g., when the stylus is located proximate to and/or in contact with the digitizer. If desired, stylus focus may be maintained separate from and/or concurrent with mouse and/or keyboard focus. Additionally, such systems and methods may accept input from multiple styli and independently and concurrently provide stylus focus with respect to control elements corresponding to the location of each stylus.

    摘要翻译： 触笔“焦点”指定或建立用于接收输入（例如电子墨水）的计算机接口的元件或区域。 例如，可以使用焦点来准备相关联的元素以通过从“待机”模式“唤醒”系统来接收输入; 通过触发增加的数字化仪轮询频率; 通过设置数据结构或分配内存资源来接收输入; 检索与输入或其特征相关的数据等。用于管理触控笔焦点的系统，方法和计算机可读介质可以包括：（a）接收指示触针位于数字化仪附近的输入; 和（b）将焦点提供给对应于触控笔位置的控制元件，例如当触针位于靠近和/或与数字转换器接触时。 如果需要，可以与鼠标和/或键盘焦点分离和/或同时保持触控笔焦点。 此外，这样的系统和方法可以接受来自多个测针的输入，并且独立地并且同时提供对应于每个触控笔的位置的控制元件的触控笔焦点。
