Blynk updates dashboard

Head bobbing a lot + some eye flutter detection?

User Puts on Device

Nothing abnormal

Blynk sends notification (to phone + any paired device)

IMU keeps tracking head motion

IR keeps an eye out on eye flutter

IMU senses any motion from the back of the head; IR tracks the movement of eyelids
