Like other Livescribe products, Echo Pro uses an imaging sensor at the pen’s tip to capture notes written on special microdot paper. A technology called “pencast” syncs these notes with audio recorded by a built-in microphone or included headset, allowing for intuitive playback after USB import.
For example, students can write down and record what their professor is saying in class, upload the resulting pencast file to Mac via the Echo Desktop app and jump to specific points in the lecture simply by tapping on their notes.
