• Keystroke: how you type on a keyboard (for instance your password)
• Tapping: the way you type (like Morse code)
• Mouse: how you move your mouse

Shiver / NeuroPrint or Neuro-Finger Print™ (NFP)

• (2017) Aerendir Mobile Inc. proposes to use the "shivering" of your hand, captured by the inertial sensors of your smartphone.
• (2018 Mar)INTERVIEW: Martin Zizi, and Pierre Pozzi, Aerendir Mobile, Inc.:
  - "NeuroPrint uses proprioceptive neurophysiology"
  - "The muscles in our hands are densely connected with our brain map. Those muscles in our hands shiver an average of 10 to 20 times a second, this shivering is nearly invisible and corresponds to individual muscle fibres controlling their length. It turns out the phone sensors are sensitive enough to measure those micro-vibrations in the hand."
