1. A method performed by an apparatus configured to improve a sleep of an object who is sleeping, the method comprising:
- determining a wake-up time of the object as a first value based on schedule information corresponding to a schedule of the object;
receiving bio-information of the object from a portable terminal;
measuring a sleep state variable of the object from the bio-information, wherein the sleep state variable comprises at least one from among a number of posture changes and respiration information;
determining whether the sleep state variable exceeds a predetermined critical value;
monitoring a sleep state of the object based on whether the sleep state variable exceeds the predetermined critical value;
receiving ambient environmental information from an environmental sensor separate from the portable terminal;
changing the wake-up time from the first value to a second value that is later than the first value based on the sleep state of the object and the ambient environmental information; and
outputting a wake-up alarm signal at the changed wake-up time.

Abstract
A method performed by an apparatus for inducing a sound sleep to induce a sound sleep of an object who is sleeping includes: determining a first wake-up time of the object based on schedule information of the object; receiving bio-information of the object; determining a sleep state of the object from the bio-information of the object; changing the first wake-up time to a second wake-up time by taking into account the sleep state of the object; and outputting a wake-up alarm signal at the second wake-up time.

7. An apparatus configured to improve a sleep of an object who is sleeping, the apparatus comprising:
-
a communicator; a controller configured to; determine a wake-up time of the object as a first value based on schedule information corresponding to a schedule of the object; control the communicator to receive bio-information of the object that is measured by a portable terminal and receive ambient environmental information from an environmental sensor separate from the portable terminal; measure a sleep state variable of the object from the bio-information, wherein the sleep state variable comprises at least one from among a number of posture changes and respiration information; determine whether the sleep state variable exceeds a predetermined critical value; monitor a sleep state of the object based on whether the sleep state variable exceeds the predetermined critical value; change the wake-up time from the first value to a second value that is later than the first value based on the sleep state of the object and the ambient environmental information; and an output device configured to output a wake-up alarm signal at the changed wake-up time. - View Dependent Claims (8, 9, 10, 11)

12. An alarm method of an apparatus configured to improve sleep of an object who is sleeping, the alarm method comprising:
-
detecting an alarm event; determining an urgency level of the alarm event; measuring a sleep depth of the object and determining whether the sleep depth is a low sleep depth, or a high sleep depth; determining an alarm condition corresponding to the sleep depth, based on the urgency level; and outputting an alarm signal related to the alarm event based on the determined alarm condition, wherein an output cycle of the alarm signal is a first cycle when the sleep depth is a low sleep depth, and the output cycle of the alarm signal is a second cycle, different than the first cycle, when the sleep depth is a high sleep depth. - View Dependent Claims (13, 14)

15. An apparatus configured to improve sleep of an object, the apparatus comprising:
-
a communicator; a controller configured to; control the communicator to receive information about an alarm event and bio-information of the object that is measured by a sensor, determine an urgency level of the alarm event, measure a sleep depth of the object based on the bio-information, determine whether the sleep depth is a low sleep depth, or a high sleep depth, and determine an alarm condition corresponding to the sleep depth, based on the urgency level; and an output device configured to output an alarm signal related to the alarm event based on the determined alarm condition, wherein the output device controls an output cycle of the alarm signal to be a first cycle when the sleep depth is a low sleep depth, and wherein the output device controls the output cycle of the alarm signal to be a second cycle, different than the first cycle, when the sleep depth is a high sleep depth. - View Dependent Claims (16)

17. An apparatus configured to control ambient noise, the apparatus comprising:
-
a communicator; an audio input device; a controller configured to; control the communicator to receive bio-information of an object that is measured from a sensor; control the audio input device to detect a noise signal, determine whether a sleep state of the object is a deep sleep state or a light sleep state, based on the bio-information, and determine a noise pattern having periodic characteristics by analyzing the noise signal; and an audio output device configured to output an anti-phase noise pattern having a phase that is opposite to a phase of the noise pattern, wherein the controller is further configured to control the audio output device, wherein an output intensity of the anti-phase noise pattern is a first level when the object is in the deep sleep state, and the output intensity of the anti-phase noise pattern is a second level, higher than the first level, when the object is in the light sleep state. - View Dependent Claims (18, 19)

20. A method performed by an apparatus configured to improve a sleep of an object who is sleeping, the method comprising:
-
determining a wake-up time of the object as a first value based on schedule information corresponding to a schedule of the object; receiving bio-information of the object from at least one from among a camera and a portable terminal; measuring a sleep state variable of the object from the bio-information, wherein the sleep state variable comprises at least one from among a number of posture changes and respiration information; determining whether the sleep state variable exceeds a predetermined critical value; monitoring a sleep state of the object based on whether the sleep state variable exceeds the predetermined critical value; receiving ambient environmental information from an environmental sensor separate from the camera or the portable terminal; changing the wake-up time from the first value to a second value that is later than the first value based on the sleep state of the object and the ambient environmental information; outputting a wake-up alarm signal at the changed 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.
