A method of providing a health care service through a terminal, the method comprising: acquiring an image in which a health care service user's health care behavior is captured and measurement information of a measurement device associated with the health care behavior; determining (S120, S130) whether or not the health care behavior is normally carried out based on the captured image by determining whether or not a position of the measurement device mounted on the user's body is correct based on the captured image; displaying a first indicator indicating that the health care behavior is not normally carried out on a screen of the terminal when the health care behavior is not normally carried out; displaying an image in which the health care behavior is captured on the screen of the terminal, wherein the first indicator is displayed at a position where the health care behavior is abnormally carried out on the screen, and wherein the captured image and the first indicator are displayed in real-time on the screen of the terminal while the health care behavior is carried out; and providing guide information for carrying out a normal health care behavior, wherein the provision of the guide information is provided through a second indicator indicating the correct health care behavior along with the displayed image, wherein providing guide information further comprises, when the position of the measurement device is incorrect, generating a control signal for controlling the measurement device to provide information indicating that the health care behavior is abnormally carried out, transmitting the control signal to the measurement device, and outputting the information indicating that the health care behavior is abnormally carried out by means of the measurement device mounted on the user's body. acquiring an image in which a health care service user's health care behavior is captured and measurement information of a measurement device associated with the health care behavior; determining (S120, S130) whether or not the health care behavior is normally carried out based on the captured image by determining whether or not a position of the measurement device mounted on the user's body is correct based on the captured image; displaying a first indicator indicating that the health care behavior is not normally carried out on a screen of the terminal when the health care behavior is not normally carried out; displaying an image in which the health care behavior is captured on the screen of the terminal, wherein the first indicator is displayed at a position where the health care behavior is abnormally carried out on the screen, and wherein the captured image and the first indicator are displayed in real-time on the screen of the terminal while the health care behavior is carried out; and providing guide information for carrying out a normal health care behavior, wherein the provision of the guide information is provided through a second indicator indicating the correct health care behavior along with the displayed image, wherein providing guide information further comprises, when the position of the measurement device is incorrect, generating a control signal for controlling the measurement device to provide information indicating that the health care behavior is abnormally carried out, transmitting the control signal to the measurement device, and outputting the information indicating that the health care behavior is abnormally carried out by means of the measurement device mounted on the user's body.
