Abstract

A method and device for calibrating a mobile terminal including a motion sensor reduces erroneous calibrations. The method of calibrating a mobile terminal by detecting an inclination of at least two directions preferably includes: activating a calibration mode for calibrating an error of the motion sensor. When a calibration mode is activated, a user interface screen for calibrating the motion sensor is output. The user interface screen outputs a coordinate system for displaying at least two facets of information; and inclination information of at least two directions received from the motion sensor is output as one image on the coordinate system.

Claims (31)

1. A calibration device of a mobile terminal, comprising:

a motion sensor for detecting inclination information about at least two directions of a current position of the mobile terminal as an ordered pair; and

a display unit for outputting, when a calibration mode is activated, inclination information about the detected at least two directions of the current position of the mobile terminal as one image on a coordinate system,

wherein when said at least two directions of a current position comprises three directions, said one image is displayed on a three-directional coordinate system to show inclination information regarding horizontal direction, vertical direction and height direction as detected by the motion sensor.

2. The calibration device of claim 1 , further comprising a controller for controlling output of a warning message notifying that the mobile terminal cannot be moved while performing a calibration of the motion sensor, when a calibration instruction of the motion sensor is input.

3. The calibration device of claim 2 , wherein the controller calculates an offset value for amending an error of the motion sensor.

4. The calibration device of claim 3 , further comprising a storage unit for storing the calculated offset value, when a calibration of the motion sensor is complete.

5. The calibration device of claim 2 , wherein the display unit displays a degree of progress of the calibration of the motion sensor.

6. The calibration device of claim 2 , wherein the controller stops the calibration of the motion sensor when a motion of the mobile terminal is detected while performing the calibration of the motion sensor, and outputs a message notifying the calibration has stopped.

7. The calibration device of claim 2 , wherein the controller stops a calibration of the motion sensor when a motion of the mobile terminal is detected while performing the calibration of the motion sensor, and outputs at least one of a message notifying the calibration has stopped and a message requested whether to recalibrate the motion sensor.

8. The calibration device of claim 2 , wherein the display unit outputs at least one concentric circle using a starting point of the coordinate system as the center.

9. The calibration device of claim 8 , wherein the controller controls the display unit to fill the at least one concentric circle with a preset specific color that corresponds to a degree of progress of the calibration.

10. The calibration device of claim 2 , wherein the controller controls the display unit to move the image in a starting point direction of the coordinate system and to output the moved image to corresponds to a progress degree of the calibration.

11. A method of calibrating a mobile terminal comprising a motion sensor for detecting an inclination of at least two directions of a current position of the mobile terminal, said method comprising:

activating a calibration mode for calibrating an error of the motion sensor;

outputting an indication when a calibration mode is activated;

displaying a coordinate system for displaying at least facets of two information; and

outputting inclination information of at least two directions received from the motion sensor as one image on the coordinate system,

wherein said at least two directions of a current position received from the motion sensor comprises three directions, said one image is displayed on a three-directional coordinate system to show inclination information in a horizontal direction, vertical direction and height direction as detected by the motion sensor.

12. The method according to claim 11 , wherein the indication output is one of a visual indication.

13. The method according to claim 11 , wherein the indication output is a user interface screen for calibrating the motion sensor that includes said two facets of information of the coordinate system.

14. The method of claim 11 , further comprising:

notifying a user that the mobile terminal cannot be moved while performing a calibration of the motion sensor, when a calibration is performed according to an input of a calibration instruction; and

displaying a degree of progress of a calibration of the motion sensor.

15. The method of claim 14 , wherein displaying a coordinate system for displaying at least two facets of information comprises outputting at least one concentric circle using a starting point of the coordinate system as the center.

16. The method of claim 15 , wherein displaying the degree of progress of a calibration of the motion sensor comprises at least one of:

filling the at least one concentric circle with a preset specific color to correspond to a progress degree; and

moving the image to a starting point of the coordinate system to correspond to the progress degree.

17. The method of claim 11 , further comprising calculating and storing an offset value for amending an error of the motion sensor.

18. The method of claim 11 , further comprising stopping a calibration of the motion sensor when the mobile terminal moves before a calibration of the motion sensor is complete.

19. The method of claim 18 , further comprising outputting at least one of a message notifying that a calibration of the motion sensor has stopped and a message requesting whether or not to recalibrate the motion sensor.
