Abstract
A method for automatically and intelligently scrolling handwritten ink entered into a computer device. The method detects when the user is on the last available line for writing, and starts a timer on each pen-up event or resets the timer on a pen-down event. An automatic scroll is performed after the writing on the last line has halted for more than a threshold amount of time. The threshold time may be variable based on criteria, such as the x-coordinate of the last writing, the writing speed of the user, the last character that was written, and the current zoom percentage of the display. The zoom percentage may also be used to determine the number of lines to scroll. New ink written after the automatic scrolling operation may be moved up to the scrolled ink, if the method determines that the user intended to write the new ink directly after the scrolled ink.
