Calm

Constantly fires and predicts user's calm level from passive cognitive state based on the alpha brainwave between 7.5Hz and 12.5Hz. Calm is a probability from 0.0 to 1.0. To get calm over 0.3 is significant. Calm will take up to 16 seconds to initialize. We normally take a longer rolling average of calm to produce brain processes over time, see how we do it in our flow walk through.

Things that can help increase the calm score are:

• Closing your eyes for 30 seconds or more
• Seating or standing still
• Breathing exercises
• Meditating
