Livescribes
Livescribes was a company known for its line of digital pens. These devices allowed users to record audio while taking notes with special paper. When a user tapped on their written notes later, the pen would play back the audio recorded at that specific moment, syncing the sound with the written word. This feature was particularly useful for students in lectures, journalists in interviews, and professionals in meetings, enabling them to review discussions alongside their annotations.
The Livescribe ecosystem typically involved a pen, a notebook with a specific dot pattern, and companion software.
