Sleep tracking method and device

A method comprising:

• receiving, from a proximity sensor located in a housing coupled to a bed and configured to receive a smart phone, an initiation signal indicative of a smart phone being proximate to the housing and of the smart phone being releasably secured in a cradle of the housing and of the smart phone starting to charge;
• causing, based at least in part on the initiation signal and a time at which the initiation signal is received, the smart phone to initiate a sleep sequence configured to promote sleep of a user proximate the housing, the sleep sequence comprising one or more of:
• causing a speaker of the smart phone to emit one or more sounds, or
• causing a screen of the smart phone to display one or more of messages or colors;
• receiving sensor data from the smart phone, the sensor data including:
• motion data determined by an accelerometer of the smart phone, the motion data indicating motion of a user in the bed during sleep, and
• sound data determined by a microphone of the smart phone, the sound data indicating a heart rate of the user during sleep;
• determining, based on the motion data and the sound data of the sensor data, a phase of sleep of the user;
• and
• based at least in part on the phase of sleep, transmitting a signal to an actuator, the signal configured to control the actuator.

A system comprising:

• a smart phone comprising at least one sensor;
• a housing comprising a cradle comprising a magnet and configured to receive mechanically the smart phone and secure the smart phone to the cradle using the magnet, the housing being configured to couple to a bed;
• the smart phone further comprising:
• one or more processors;
• and
• one or more non-transitory computer readable media having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform the operations comprising:
• receiving an initiation signal indicative of the smart phone being in the cradle and of the smart phone starting to charge and one or more of:
• a current time,
• a location of the smart phone,
• a detection of a near field communication code at the cradle, or
• a command from a user;
• causing, based at least in part on the initiation signal, the smart phone to initiate a sleep sequence;
• receiving motion data detected by one or more accelerometers of the smart phone;
• determining, based on the motion data, a phase of sleep of a user sleeping proximate the housing;
• and
• based at least in part on the phase of sleep, transmitting a signal to an actuator, the signal configured to control the actuator.
