Entraining Respiration
Systems and methods are provided that provide respiration entrainment cues to a user to encourage relaxation or a sleep state. The entrainment cues may be audible, visible, or tactile (or any combination). The entrainment cues include a rhythmic component associated with a target respiration rate and may include sub-components associated with a target breath architecture, such as an inhale-exhale cycle. The systems and methods detect the user's respiration to determine whether the user's respiration matches the entrainment cues or whether the user has fallen asleep.

- 1. An apparatus comprising:
an input configured to be coupled to a biometric sensor and to receive sensor information about respiration of a user; an output configured to be coupled to a transducer, the output configured to provide signals to control the transducer; and a processor coupled to the input and the output and configured to:
cause the transducer to provide entrainment cues having a rhythmic component at a target respiration rate,
determine a respiration rate of the user, based at least in part upon the sensor information, and
cause the transducer to cease providing entrainment cues responsive to determining that the user's respiration rate meets a sleep criterion.
- 8. A method of encouraging relaxation in a user, the method comprising:
producing entrainment cues having a rhythmic component at a target respiration rate; detecting the user's respiration rate; determining whether the user's respiration rate meets a criterion; and adjusting the entrainment cues responsive to determining that the user's respiration rate meets the criterion.
- 16. An apparatus comprising:
a sensor configured to detect respiration of a user; and a processor coupled to the sensor and having an output configured to be coupled to a loudspeaker and configured to:
cause the loudspeaker to play entrainment sounds having a rhythmic component at a first target respiration rate,
determine a respiration rate of the user, based at least in part upon the sensor, and
adjust the rhythmic component to a second target respiration rate responsive to determining that the user's respiration rate matches the first target respiration rate.
