Brain Wave to Ear Movement Code

ToDoList - This section needs to be fleshed out! Drastically!

Measurable variables from neurosky

  • Poor_signal - amount of noise on the eeg.
  • Meditation™ eSense - between 0 and 100, with 40-60 being normal. Custom neurosky value
  • Attention™ eSense - between 0 and 100, with 40-60 being normal. Custom neurosky alue
  • Eye blink strength. 0-255. Relative to previous value. May not actually be available.
  • EEG Power. 8 bands. Value is relative to eachother.
    • delta (0.5 - 2.75Hz),
    • theta (3.5 - 6.75Hz),
    • low-alpha (7.5 - 9.25Hz),
    • high-alpha (10 - 11.75Hz),
    • low-beta (13 - 16.75Hz),
    • high-beta (18 - 29.75Hz),
    • low-gamma (31 - 39.75Hz), and
    • mid-gamma (41 - 49.75Hz).
  • Raw wave: 16 bit value: short raw = (Value[0]«8) | Value[1]; where Value[0] is the high-order byte, and Value[1] is the low-order byte.
