Continuous Handwriting UI

摘要

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.

主权项

1. A non-transitory machine readable storage medium storing a program for execution by at least one processing unit, the program for providing a handwriting area on an electronic display, the program comprising sets of instructions for:
receiving handwritten input via a touch-sensitive input device and detecting a set of text characters for the handwritten input; displaying the handwritten input in the handwriting area and the set of detected text characters in a text area of the electronic display; and when the handwritten input in the handwriting area exceeds a threshold, modifying a display of a subset of the handwritten input within the handwriting area.
