Abstract

Abstract A note-taking system based on a notepad computer with an integrated audio/video-recorder is described. A document is created or retrieved. As the user types on the keyboard or writes with the stylus or similar input instrument, each character or stroke that is input by the user is invisibly time-stamped by the computer. The audio/video stream is also continuously time-stamped during recording. To play a section of recording back, the user selects part of the note (perhaps by circling it with a stylus) and invokes a "playback selection" command. The computer then examines the time-stamp and "winds" the record to the corresponding place in the audio/video recording, where it starts playing - so that the user hears and/or sees what was being recorded at the instant the selected text or strokes were input. With a graphical user interface, the user may input key "topic" words and subsequently place check marks by the appropriate word as the conversation topic veers into that neighborhood.
