    • Described is a computer-implemented system and method that detects and differentiates scratch-out gestures from other electronic ink, e.g., entered via a pen. The system and method compare boundary-based criteria to differentiate, which eliminates the need to have a specially-shaped scratch-out pattern, instead allowing a wide variety of scratch-out styles to be detected. Criteria includes boundary-based evaluations such as whether the potential scratch-out gesture intersects previously recognized words or characters, whether the scratch-out gesture has a width that is at least a threshold percentage of the width of a word or character bounding box, whether the electronic ink extends beyond the midpoint of the bounding box, and whether at least some portion of the scratch-out gesture is above a baseline of the word or character. Scratch-out gestures entered in freeform input writing areas and boxed input writing areas are supported.
    • 描述了一种计算机实现的系统和方法,其检测和区分例如通过笔输入的其他电子墨水的划痕手势。 系统和方法比较基于边界的标准来区分,这样就不再需要特殊的划痕模式,而是可以检测出各种各样的划痕样式。 标准包括基于边界的评估,例如潜在的刮除手势是否与先前识别的单词或字符相交,是否划出手势的宽度至少是单词或字符边界框的宽度的阈值百分比,无论是否 电子墨水延伸超过边界框的中点,以及刮除手势的至少一部分是否高于单词或字符的基线。 支持自由输入写入区域和盒装输入写入区域中输入的划痕手势。

    • A method and apparatus for receiving strokes of electronic ink in more than one language is provided. An input device is used to enter at least one stroke of electronic ink into a processing device. The processing device stores a language indication associated with the electronic ink, such that the language indication provides a way to associate a handwriting recognizer with the ink. The user may change the language or recognizer associated with the ink by flipping over a pen and using another tip of the pen or may use another pen or other input device. Aspects of the described system and method accommodate various optional interfaces to associate a pen tip or click of a button to one or more languages. Other aspects of the system and method include language switching of a displayed software keyboard when a pen input device is within a predetermined distance from a display.
    • 提供一种用于以多种语言接收电子墨水笔画的方法和装置。 输入装置用于将电子墨水的至少一冲程输入到处理装置中。 处理装置存储与电子墨水相关联的语言指示,使得语言指示提供了将手写识别器与墨水相关联的方式。 用户可以通过翻转笔并使用笔的另一个尖端来改变与墨水相关联的语言或识别器,或者可以使用另一笔或其他输入设备。 所描述的系统和方法的方面适应各种可选接口以将笔尖或按钮的点击与一种或多种语言相关联。 系统和方法的其他方面包括当笔输入设备距离显示器在预定距离内时显示的软件键盘的语言切换。
