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. If the user leaves more than a threshold amount of blank space at the bottom of the page immediately preceding the new page, then an implicit page break may be inserted at the beginning of the new page. The amount of blank space left at the end of the preceding page may be combined with other criteria to determine whether to insert an implicit page break. The amount of time elapsed since ink has been captured on the previous page is another factor that may be used by itself or combined with other factors 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.
