System and method for controlling temperature of user

1. A wearable device for a service for controlling a temperature for a user, comprising:

a first temperature measurement unit configured to measure a temperature of the user; and

a control unit configured to:

calculate a temperature difference by comparing the measured temperature with a previously stored temperature of the user at normal times;

provide temperature measurement information to an external device when the calculated temperature difference is greater than a reference temperature difference for a predetermined amount of time; and

receive, from the external device, service information for controlling the temperature for the user based on the temperature measurement information, wherein the service information comprises at least one of information regarding food provided by stores, or information regarding a coupon or a rewards point provided by the stores, and wherein the stores provide a service for controlling the temperature for the user and are located in a short distance from the location of the user.

2. The wearable device of claim 1 , wherein the wearable device further comprises:

a second temperature measurement unit configured to measure an external temperature; and

a display unit configured to display at least one of the measured temperature, the measured external temperature, the temperature difference, the reference temperature difference, or the service information for controlling the temperature for the user.

3. The wearable device of claim 1 , wherein: the temperature of the user at the normal times is the measured external temperature at the normal times.

4. The wearable device of claim 1 , wherein, when an air-conditioning control device is sensed through a short-range communication, the control unit is configured to:

transmit the temperature measurement information to the sensed air-conditioning control device;

receive, from the air-conditioning control device, a question about whether a current temperature is proper; and

respond to the question.

5. The wearable device of claim 1 , wherein, when the air-conditioning control device is not sensed through the short-range communication, the control unit is configured to:

transmit, to a service server, the temperature measurement information; and

receive, from the service server, the service information for controlling the temperature for the user based on location information of the user and temperature information of the user.

6. The wearable device of claim 1 , wherein the temperature measurement information comprises at least one of the measured temperature, the external temperature, the temperature difference, or the location information of the user.

7. A service server for controlling a temperature for a user, comprising:

a communication unit configured to communicate with a wearable device over a communication network; and

a personalized service unit configured to:

generate service information for controlling the temperature for the user based on location information of the user and temperature information of the user when the communication unit transmits temperature measurement information comprising the location information of the user and the temperature information of the user;

provide the service information to the wearable device;

check stores located in a short distance from the location of the user;

identify stores that provide a service for controlling the temperature for the user among the checked stores; and

generate the service information for controlling the temperature for the user, wherein the service information comprises at least one of information regarding food provided by the identified stores, or information regarding a coupon or a rewards point provided by the identified stores.

8. The service server of claim 7 , wherein, when an air-conditioning control device is present in the location information, the personalized service unit is configured to:

transmit, to the wearable device, a question about whether a current temperature of the air-conditioning control device is proper; and

control a temperature of the air-conditioning control device based on a response from the wearable device.

9. The service server of claim 7 , wherein the service server further comprises:

a database configured to store store-related information comprising at least one of information regarding a store name, information regarding a store location, information regarding a commodity, or information regarding a coupon or a rewards point.
