Method and apparatus for improving and monitoring sleep

1. A method performed by an apparatus configured to improve a sleep of an object who is sleeping, the method comprising:

determining a first wake-up time of the object based on schedule information corresponding to a schedule of the object;

receiving bio-information of the object;

determining a sleep state of the object from the bio-information;

changing the first wake-up time to a second wake-up time based on the sleep state of the object;

outputting a wake-up alarm signal at the second wake-up time;

measuring an actual wake-up time of the object;

determining a remaining time from the actual wake-up time of the object to a preset critical time;

selecting at least one activity that is to be performed by the object during the remaining time; and

providing information about the selected at least one activity to the object.

2. A non-transitory computer-readable recording medium having embodied thereon a program for executing the method of claim 1 .

3. A method performed by an apparatus configured to improve a sleep of an object who is sleeping, the method comprising:

determining a first wake-up time of the object based on schedule information corresponding to a schedule of the object;

receiving bio-information of the object;

determining a sleep state of the object from the bio-information;

changing the first wake-up time to a second wake-up time based on the sleep state of the object;

outputting a wake-up alarm signal at the second wake-up time;

detecting that the object wakes up; and

providing information about an event that occurs within a preset time after the object wakes up.

4. A non-transitory computer-readable recording medium having embodied thereon a program for executing the method of claim 3 .

5. An apparatus configured to improve a sleep of an object who is sleeping, the apparatus comprising:

a communicator configured to receive bio-information of the object that is measured by a sensor;

a controller configured to determine a sleep state of the object based on the bio-information, determine a first wake-up time of the object based on schedule information corresponding to a schedule of the object, and change the first wake-up time to a second wake-up time based on the sleep state of the object; and

an output device configured to output a wake-up alarm signal at the second wake-up time,

wherein

the controller is further configured to detect that the object is sleeping within a preset time after the second wake-up time, and

the communicator is further configured to transmit information indicating that the object is sleeping to a device of a designated third party.

6. An apparatus configured to improve a sleep of an object who is sleeping, the apparatus comprising:

a communicator configured to receive bio-information of the object that is measured by a sensor;

a controller configured to determine a sleep state of the object based on the bio-information, determine a first wake-up time of the object based on schedule information corresponding to a schedule of the object, and change the first wake-up time to a second wake-up time based on the sleep state of the object; and

an output device configured to output a wake-up alarm signal at the second wake-up time,

wherein

the output device comprises a first device and a second device, the second device being different from the first device, and

the controller is further configured to output a first wake-up alarm signal through the first device at the second wake-up time, and, in response to it being detected that the object is sleeping within a preset time after the second wake-up time, output a second wake-up alarm signal through the second device.
