What is the CAP sensor for?

The capacitive (CAP) sensor helps to recognize if a person is wearing AYO or not. From user's perspective, that can allow you, during a session, to pause the AYO session automatically and to continue with the session just by removing the AYO wearable from your head and then putting it back on your head. 

For example, if you are in the midst of a session and you need to take the AYO wearable off for a few minutes and then put it back on, when you take it off the lights will go off automatically. And when you put it back on, the lights will turn on automatically. So if you'd like to try out this functionality to see if it is something that makes the AYO usage for you more convenient, feel free to go to the goAYO app -> Settings -> CAP sensor -> turn it "on".
