  • Publication number: 20050053284
    Abstract: A logical separation between pages, such as an implicit page break, is introduced to separate text entered during one handwriting session from text entered during another handwriting session. The amount of time elapsed since ink has been captured on the previous page is a factor that may be used to determine whether to insert an implicit page break into the new page. A change in context, such as a different date or different recognized subject matter labels, is also a factor that may be considered in determining whether to insert an implicit page break.

  • Publication number: 20050025363
    Abstract: 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.

  • Publication number: 20020093501
    Abstract: Digitized handwriting is captured and provided in real-time to a display in the form of polylines. The polylines are then converted to a parametric representation, thereby filtering out noise and distortion effects attributable to the digitization process. To further refine quality, the smoothed, digitized handwriting is further subjected to edge-smoothing processing to mitigate the effects of relatively low-resolution displays. In this manner, the present invention improves the appearance of digitized handwriting in comparison to prior art techniques.
