As per ThinkGear Communication Protocol EEG_POWER
section:
This Data Value represents the current magnitude of 8 commonly-recognized types of EEG frequency bands (brainwaves). It consists of eight 4-byte floating point numbers in the following order: 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). These values have no units and therefore are only meaningful when compared to each other and to themselves, for considering relative quantity and temporal fluctuations. The floating point format is standard big-endian IEEE 754, so the 32 bytes of the Values can therefore be directly cast as a float* in C (on big-endian environments) to be used as an array of floats.
Also notice the eeg[i] data can be retrieved as individual values:
eeg[0] = delta()
eeg[1] = theta()
eeg[2] = lowAlpha()
eeg[3] = highAlpha()
eeg[4] = lowBeta()
eeg[5] = highBeta()
eeg[6] = lowGamma()
eeg[7] = midGamma()
(e.g. mindwave.eeg()[0]
is the same as mindwave.delta()
, etc.)
Hope this thelps,
