摘要： A user interface allows a user to input handwritten, key-press, and spoken text in a seamless, synchronized manner. A text input panel accepts soft keyboard presses and handwritten words, characters, and gestures. A text recognizer/synchronizer integrates textual input from various sources while recognizing and preserving the order in which a user entered text via the soft keyboard, via handwriting, and/or by speaking. Synchronized text may be displayed in a stage area of the text input panel before being passed to an operating system message router and/or an application program. While in handwriting recognition mode, various permutations and combinations of a word recognition area, a character recognition area, and a keybar/keypad may optionally be displayed.

摘要： A technique is disclosed for detecting an in-air gesture made by a digitizing pen above a digitizing writing surface. When the digitizing pen is determined to be in motion above the digitizing writing surface, positional information of the digitizing pen with respect to the surface of the digitizing writing surface is recorded within a moving buffer. The moving buffer records a predetermined amount of positional information spanning a predetermined amount of time while the digitizing pen is in motion above the digitizing writing surface. When the digitizing pen has stopped motion, positional information recorded in the moving buffer is evaluated for determining whether the recorded information corresponds to a predetermined in-air gesture. A predetermined user interface panel is displayed when the positional information recorded in the moving buffer corresponds to a predetermined in-air gesture.
摘要翻译： 公开了一种用于检测由数字化笔在数字化书写表面上方进行的空中手势的技术。 当确定数字化笔在数字化写入表面上方运动时，数字化笔相对于数字化写入表面的位置信息被记录在移动缓冲器内。 当数字化笔在数字化书写表面上运动时，移动缓冲器记录跨越预定时间量的预定量的位置信息。 当数字化笔停止运动时，评估记录在移动缓冲器中的位置信息，以确定所记录的信息是否对应于预定的空中手势。 当记录在移动缓冲器中的位置信息对应于预定的空中手势时，显示预定的用户界面面板。

摘要： A system and method for emulating the functional behavior of a two-button mouse-type computer input device is described. A predetermined input generated by digitizing pen and a digitizing writing surface is received, and a user interface having a plurality of soft buttons is displayed. The plurality of soft buttons provides selectable functionality of a two-button mouse-type computer input device. Preferably, the plurality of soft buttons includes a right-button function, a shift function, a control function, an alternate function and a bull's-eye function.
摘要翻译： 描述了用于模拟双按钮式计算机输入装置的功能行为的系统和方法。 接收由数字化笔和数字化书写表面产生的预定输入，并且显示具有多个软按钮的用户界面。 多个软按钮提供双按钮式计算机输入装置的可选功能。 优选地，多个软按钮包括右按钮功能，移位功能，控制功能，交替功能和牛眼功能。
