SYSTEMS AND METHODS FOR GENERATING AND CONTROLLING TEMPORARY DIGITAL INK

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.
