Abstract
A sleep sensing system comprising a sensor to obtain real-time information about a user, a sleep state logic to determine the user's current sleep state based on the real-time information. The system further comprising a sleep stage selector to select an optimal next sleep state for the user, and a sound output system to output sounds to guide the user from the current sleep state to the optimal next sleep state.
Claims (32)
1. A smart sleep system comprising:
a sensor configured to obtain real-time information about a user on a sleep surface;
a processor configured to determine the user's current sleep state based on the real-time information from the sensor;
the processor further configured to determine whether a user should be moved to an optimal next sleep state, and select a next sleep state for the user based on the user's current sleep state and external data;
a temperature controller configured to receive a command from the processor to adjust a temperature for the user on the sleep surface, to guide the user from the current sleep state to the next sleep state;
the processor configured to adjust one or more conditions to keep the user in the current sleep state, when the optimal next sleep state is the same as the current sleep state, the adjusting including sending the command to the temperature controller to adjust the temperature; and
the processor further configured to guide the user to the optimal next sleep state, after keeping the user in the current sleep state.
2. The smart sleep system of claim 1 , further comprising:
the processor using the external data from a clock to determine the next sleep state for the user, wherein the next sleep state is a lighter sleep state when a waking time of the user is approaching.
3. The smart sleep system of claim 2 , further comprising:
the processor using the external data from a calendar to determine the next sleep state for the user.
4. The smart sleep system of claim 1 , wherein the adjusting of the one or more conditions comprises altering one or more of: the temperature, light, humidity, mattress firmness, tactile stimulus, olfactory stimulus, or sound.
5. The smart sleep system of claim 1 , wherein the sensor comprises one or more of an accelerometer, a pressure sensor, a thermometer, a heart rate monitor, or a brainwave monitor.
6. The smart sleep system of claim 5 , wherein the sensor further comprises one or more of: environmental sensor, an interface to home environment controls to receive environmental data, and an interface to a home automation system to receive environmental data.
7. The smart sleep system of claim 1 , wherein the sensor comprises a temperature sensor to sense a body temperature of the user.
8. A method comprising:
determining a current sleep phase of a user based on sensor data from at least one sensor;
determining an optimal next sleep phase for the user based the sensor data and external data;
when the user should be moved to the optimal next sleep phase, utilizing an output system to adjust a temperature to shift the user's body temperature to guide the user to the optimal next sleep phase;
adjusting one or more conditions to keep the user in the current sleep phase, when the optimal next sleep phase is the same as the current sleep phase; and
adjusting the one or more conditions to move the user to a subsequent sleep phase, after keeping the user in the current sleep phase.
9. The method of claim 8 ,
wherein adjusting the one or more conditions includes adjusting one or more of: sound, tactile output, light level, visual output, scent, humidity, and mattress firmness.
10. The method of claim 8 , further comprising:
using data from the at least one sensor, indicating sleep state data for a current sleep period, to determine the optimal next sleep phase for the user.
11. The method of claim 8 , further comprising:
using data from a clock and an alarm logic to determine the optimal next sleep phase for the user.
12. The method of claim 8 , further comprising:
sending commands to one of a home environment controller or a home automation system, to adjust the one or more conditions.
13. The method of claim 12 , further comprising:
receiving environmental data from the one of the home environment controller and the home automation system.
14. The method of claim 8 , wherein the at least one sensor is implemented in one of: an armband, a mobile telephone, a wristband, a pillow, or a sleep mask.
