1. A method executed in a wearable device, the method comprising:

  • obtaining, by a motion coprocessor of the wearable device, a set of motion sensor data samples from a motion sensor of the wearable device, the set of motion sensor data samples being obtained while an applications processor of the wearable device is in a sleep state and a user interface component of the wearable device is in an inactive state;

    analyzing, by the motion coprocessor, the set of motion sensor data samples using one or more detection processes to detect a raise gesture;

    in response to detecting the raise gesture, waking, by the motion coprocessor, the applications processor from the sleep state;

    executing, by the applications processor, a confirmation process on at least a portion of the set of motion sensor data samples to confirm the detected raise gesture;

    determining, by the applications processor, whether the user interface component should be activated, the determination being based at least in part on a result of the confirmation process; and

    in response to determining that the user interface component should be activated, activating, by the applications processor, the user interface component.
