Want to know how you are progressing with your meditation? That is exactly what KP Kaiser wanted to monitor. KP originally built an Arduino setup that measured skin temperature, heart rate and skin conductivity in an effort to determine the depth achieved in a meditative state.
A few months later KP developed an iOS app called Buddha Mind which focuses on heart rate variability for meditation quality.
And so, I started out building an Arduino based device to measure galvanic skin response, skin temperature, and heart rate. Within a few months, I found the most major physiological changes from meditation occur in the heart rate.
Finally, not being satisfied with a software only solution he added a DMX lighting component which utilized an arduino and electric imp for a meditative light show.
Once the user starts meditating, our algorithm tracks the heart data, waiting for the heart rate variability to reach a threshold. Once reached, buddha mind makes API call to the Electric Imp to tell it to begin sending the Arduino the trigger for running the meditation lights.
