- Patent for removing click and writing noise in a smartpen - Systems for removing or attenuating friction and/or click noise generated during writing with a smart pen are disclosed. In a smart pen, the writing cartridge is biased towards a first side of the smart pen internal cavity by a low-force biasing system without affecting writing cartridge movement. For example, the writing cartridge is comprised of a magnetic material and a magnet is embedded into the first side of the smart pen internal cavity to bias the writing cartridge towards the first side. Alternatively, the material comprising the writing cartridge or smart pen internal cavity is modified, reducing friction between the components. As another alternative, a DSP method identifies analyzes one or more parameters of received audio data to differentiate click noise from audio data, and may receive data from a movement sensor indicating when the writing cartridge has moved to reduce power consumption for identifying click noise.

- Livescribe Smart Pen in learning
- Pen that never forgets link - Dervishaj’s entire grade 7 math class has been outfitted with “smart pens” made by Livescribe, a start-up based in Oakland, Calif. The pens perform an interesting trick: when Dervishaj and her classmates write in their notebooks, the pen records audio of whatever is going on around it and links the audio to the handwritten words. If her written notes are inadequate, she can tap the pen on a sentence or word, and the pen plays what the teacher was saying at that precise point.
- “It’s like having your own little personal teacher there, with you at all times,” Dervishaj said.
- Changes the class - Can make the class less stressful, and note taking style changes to emphasize "key words" which can be used like handwritten tags to let students locate certain moments in the recording.
