Livescribe DESKTOP VERSION 1.2 - Manual (Page 13)

imaginary square grid. The dots are slightly displaced from the grid, with each dot in
one of four possible positions, forming the proprietary Anoto dot pattern.
The dot pattern identifies the specific page and locations on the page of the notes
you write. The Pulse™ smartpen uses the dot pattern in a way similar to a
geographical positioning system (GPS). But, instead of identifying locations on land,
it finds locations on paper and stores your writing as digital ink using those locations.
Using this patented dot-positioning system (DPS), the smartpen precisely tracks its
own movement on paper. As a result, anything you write – words, numbers or
drawings – can be stored, recognized, and intelligently responded to.
The area of the entire Anoto dot pattern is huge, and represents a piece of paper the
combined size of Europe and Asia. Livescribe dot paper is based on a portion of the
Anoto dot pattern.
How the Pulse Smartpen Works
When you power on the Pulse smartpen and begin writing on Livescribe paper, the
smartpen captures and stores the notes you write. To capture your writing, the
smartpen uses its built-in infrared camera to take digital snapshots of the dot pattern
as the tip moves over the paper as you write.
When recording audio in a Paper Replay™ session, the smartpen links the recorded
audio to your notes based on the dot pattern on the page. With this information, the
smartpen can play back the audio that was recorded at the exact time you were
writing your notes. Specifically, when you tap on your notes with the smartpen, it
locates the position where you are tapping and starts to play back the audio at the
position linked to that paper location.
