Abstract

A handwriting guide including an active and/or inactive writing guide is rendered by displaying a shaded outline object having a line for receiving electronic ink, displaying the active writing guide thereby indicating a location of a current active context, and expanding the active and/or inactive writing guide up to a maximum width of the outline object in response to receiving more electronic ink within a line. The active writing guide can comprise a bracket displayed on each corner of a writing area distinguished on a line and can correspond to an insertion point upon switching to text mode. A drawing guide that includes an active and/or inactive drawing guide is rendered by displaying a shaded drawing guide and the active drawing guide in response to detecting ink strokes within the drawing guide. The active drawing guide can comprise a bounding rectangle encompassing a drawing area that receives ink strokes.

Claims

in response to the at least one line within the outline object being currently active to receive inputs of the electronic ink, displaying the active writing guide around the at least one line thereby indicating a location of a current active context;

transitioning from a text mode for receiving text characters to a pen mode for receiving electronic ink;

in response to transitioning from the text mode to the pen mode, displaying the active writing guide of the pen mode around the at least one line wherein the at least one line comprises a line in which an insertion point was last displayed prior to the transition and wherein commands applied to the insertion point are also applied to electronic ink within the active writing guide without selecting the electronic ink within the active writing guide; and

in response to a non-insertion point selection being active when transitioning from text mode to pen mode, not displaying the active writing guide.

2. The method of claim 1, wherein displaying the active writing guide comprises displaying at least one bracket defining a writing area currently active to receive inputs of electronic ink.

3. The method of claim 1, further comprising at least one of distinguishing a display of the outline object from any region not occupied by the outline object and in response to receiving more electronic ink within the at least one line, expanding the active writing guide up to a maximum width of the outline object.
