This device will allow a user to capture, skim and browse an audio recording in conjunction with notes written on paper. After attending a lecture or meeting, a user may be missing information from their notes, want more detail for a topic, or to review the original material. The Audio Notebook synchronizes notes written on paper with an audio recording. The user's natural activity (i.e. writing and page turns) serve as implicit indices into the audio. The spatial layout of writing on the page enables a user to rapidly navigate in a time-dependent medium like speech.

• Familiar objects like paper and pen are used for interaction rather than artifacts left over from analog devices (e.g. FF and REW controls).
• An audio scrollbar provides a time line of the audio associated with each page of notes.
• As a user flips through physical pages of notes, the audio scans to the content of each page.
• Automatic segmentation of the audio based on acoustic cues will be combined with the user activity to structure the audio.
