Abstract: An ear stimulation device and related systems and methods for operating an ear stimulation device in connection with a computing device are described. Multiple factors are used in controlling the ear stimulation device, including a variety of factors relating to or influencing the state of the user. In various aspects, the system is also responsive to inputs from sensors or computing networks. System features include fault detection, stimulus cycling and sequencing, integration with other devices in a networked system, device control based on playlists, battery charging, and device status display features.
