Mobile healthcare device and method of operating the same

1. A method of operating a mobile healthcare device, the method comprising:

displaying, by a display, a guidance screen for guiding a posture of a user;

receiving, from the user, an input at first electrodes and second electrodes of the mobile healthcare device, the first electrodes and the second electrodes being external to the display;

changing, by the display, the guidance screen to a dynamic screen for guiding the user to maintain the posture to prevent generation of motion artifacts, in response to the input being received at the first electrodes and the second electrodes while the guidance screen is displayed, the dynamic screen including an image that is changed according to time;

measuring, by a processor, bio information of the user, in response to the input being received at the first electrodes and the second electrodes while the dynamic screen is displayed; and

in response to the bio information being measured, changing, by the display, the dynamic screen to a new screen indicating state information of the user that is obtained based on the bio information that is measured.

2. The method of claim 1 , wherein the dynamic screen is displayed for 10 seconds or less.

3. The method of claim 1 , wherein the bio information comprises a body impedance of the user.

4. The method of claim 1 , wherein the state information comprises any one or any combination of body fat, a skeletal muscle mass, a muscle mass, a degree of obesity, a muscle strength, an edema value, a body composition ratio, and an amount of intra-abdominal fat.

5. The method of claim 1 , further comprising storing user information comprising any one or any combination of a height, a gender, and a weight of the user.

6. The method of claim 1 , wherein the first electrodes are exposed through an inner surface of the mobile healthcare device, and are configured to contact a wrist of the user, and

the second electrodes are exposed through an outer surface of the mobile healthcare device, and are configured to be touched by a finger of the user.

7. The method of claim 1 , wherein an area of either one or each of the second electrodes is less than or equal to 0.2 cm 2 .

8. A mobile healthcare device comprising:

first electrodes and second electrodes configured to receive an input from a user;

a display configured to display a guidance screen for guiding a posture of the user, the first electrodes and the second electrodes being external to the display; and

a processor configured to:

control the display to change the guidance screen to a dynamic screen for guiding the user to maintain the posture to prevent generation of motion artifacts, in response to the input being received at the first electrodes and the second electrodes while the guidance screen is displayed, the dynamic screen including an image that is changed according to time;

control to measure bio information of the user, in response to the input being received at the first electrodes and the second electrodes while the dynamic screen is displayed; and

in response to the bio information being measured, control the display to change the dynamic screen to a new screen indicating state information of the user that is obtained based on the bio information that is measured.

9. The mobile healthcare device of claim 8 , wherein the dynamic screen is displayed for 10 seconds or less.

10. The mobile healthcare device of claim 8 , wherein the bio information comprises a body impedance of the user.

11. The mobile healthcare device of claim 8 , wherein the state information comprises any one or any combination of body fat, a skeletal muscle mass, a muscle mass, a degree of obesity, a muscle strength, an edema value, a body composition ratio, and an amount of intra-abdominal fat.

12. The mobile healthcare device of claim 8 , further comprising a memory configured to store user information comprising any one or any combination of a height, a gender, and a weight of the user.

13. The mobile healthcare device of claim 8 , wherein the first electrodes are exposed through an inner surface of the mobile healthcare device, and are configured to contact a wrist of the user, and

the second electrodes are exposed through an outer surface of the mobile healthcare device, and are configured to be touched by a finger of the user.

14. The mobile healthcare device of claim 8 , wherein an area of either one or each of the second electrodes is less than or equal to 0.2 cm 2 .

15. A method of operating a mobile healthcare device, the method comprising:

displaying, by a display, a guidance screen for guiding a user to contact first electrodes and second electrodes of the mobile healthcare device, the first electrodes and the second electrodes being external to the display;

receiving, from the user, an input at the first electrodes and the second electrodes;

in response to the input being received at the first electrodes and the second electrodes while the guidance screen is displayed, changing, by the display, the guidance screen to a dynamic screen for guiding the user to maintain the input to prevent generation of motion artifacts, the dynamic screen including an image that is changed according to time;

measuring, by a processor, bio information of the user, in response to the input being received at the first electrodes and the second electrodes while the dynamic screen is displayed; and

in response to the bio information being measured, changing, by the display, the dynamic screen to a new screen indicating state information of the user that is obtained based on the bio information that is measured.
