Abstract
A system and method for determining an in-ear status of a wearable audio device includes determining that the device is in motion by monitoring a first sensor (e.g., an accelerometer) and determining that an acceleration is greater than an acceleration threshold. Once motion is determined, a second sensor (e.g., a capacitive sensor) is activated; contact with a body is determined based on contact data from the second sensor (e.g., a capacitance being greater than a capacitance threshold). Once contact is determined, a third sensor (e.g., an infrared sensor) is activated; proximity to the body is determined based on infrared data from third sensor (e.g., infrared data being greater than an infrared threshold). Once proximity is determined, the device changes its status to in-ear.
