Techniques for generating temporary digital ink on media are provided.
Marks or gestures are made using one or more temporary digital inks on
media, such as an digital document. Digital ink may be dynamically
determined to be permanent or temporary. Each mark or gesture using
temporary digital inks may fade based on at least one condition. The
conditions include a predetermined time determined based on, a first
stroke of the temporary digital ink, completion of the temporary digital
ink, appearance of the temporary digital ink to another user, a first
stroke of a succeeding group of digital ink, and a stroke of the
succeeding digital ink is completed. Conditions may also include changing
display attributes, such as color and thickness of digital ink, and
fading or switching in reaction to an audio or video signal.
