Abstract
Some embodiments provide a touch-sensitive device that includes a handwriting area for receiving a handwritten input and a text area for displaying text characters that have been recognized for the handwritten input. As the device receives a subsequent handwritten input, it continuously removes portions of previously handwritten input from the handwriting area in order to allow the user to continue to provide handwritten input without having to clear the handwriting area. Some embodiments apply a fading mechanism for removing the handwritten input from the handwriting area. Different embodiments apply different factors for determining when and how to remove handwritten input from the handwriting area, including character based, word base, location based, and timer based thresholds.
