Abstract

An electronic device includes a first housing, a second housing, a rollable display, a magnetic sensor, and a processor. The magnetic sensor is disposed at a first position in the second housing coupled with the first housing in a first state. The magnetic sensor is configured to move from a first position to a second position based on a movement of the second housing in the first state so that the first housing and the second housing are coupled in a second state and to move from the second position to the first position based on a switching from the second state to the first state. The processor is configured to: electrically connect to the magnetic sensor, obtain geomagnetic data based on a movement of the magnetic sensor, and obtain correction data based on the obtained geomagnetic data.

Claims (33)

1. An electronic device comprising:

a housing comprising a first housing and a second housing coupled to the first housing to be movable relative to the first housing;

a roller part;

a drive part connected to the roller part;

a rollable display comprising:

a first part disposed adjacent to the second housing, and

a second part surrounding the roller part and having a portion disposed inside the electronic device;

a geomagnetic sensor attached to the rollable display and disposed at a position corresponding to the second part;

a structure detection sensor configured to detect the movement of the second housing in the first state relative to the first housing; and

at least one processor configured to electrically connect to the geomagnetic sensor,

wherein:

the geomagnetic sensor is disposed at a first position in the second housing coupled with the first housing in a first state,

the geomagnetic sensor is configured to move from the first position to a second position based on a movement of the second housing in the first state relative to the first housing so that the first housing and the second housing are coupled in a second state,

the geomagnetic sensor is configured to move from the second position to the first position based on a switching from the second state to the first state, and

the at least one processor is further configured to:

obtain geomagnetic data; while a position of the geomagnetic sensor is changing, wherein the geomagnetic data is distorted first data; and

obtain correction data by correcting the obtained geomagnetic data, wherein the correction data is second data corrected based on the distorted first data.

2. The electronic device of claim 1 , wherein the at least one processor is further configured to drive the magnetic sensor in response to the detected movement of the second housing.

3. The electronic device of claim 1 , wherein the drive part is configured to move the second housing through a motor operated by an electrical signal.

4. The electronic device of claim 1 , wherein the drive part is configured to move the second housing through a spring.

5. The electronic device of claim 1 , wherein the geomagnetic data is greater than or equal to a configured threshold value.

6. The electronic device of claim 5 , wherein the configured threshold value is an amount of change in a three-dimensional vector of the geomagnetic data.

7. The electronic device of claim 1 , wherein the electronic device further comprises an interface displayed on the rollable display by utilizing the correction data according to a user's input.

8. A method of correcting geomagnetic data of an electronic device having a rollable display, a geomagnetic sensor attached to the rollable display, and structure detection sensor, the method comprising:

obtaining geomagnetic data from the geomagnetic sensor based on a movement of the second housing relative to the first housing, the movement of the second housing changing an area where the rollable display is exposed to an outside of the electronic device and a position of the geomagnetic sensor, wherein the geomagnetic data is distorted first data;

detecting the movement of the second housing relative to the first housing;

activating the magnetic sensor in response to the detection;

obtaining correction data by correcting the obtained geomagnetic data, wherein the corrected data is second data corrected based on the distorted first data.

9. The method of claim 8 , wherein the detecting is performed by a structure detection sensor of the electronic device.

10. The method of claim 8 , wherein the detecting is performed by an optical distance sensor.

11. The method of claim 8 , wherein the obtaining of the geomagnetic data comprises determining whether the obtained geomagnetic data is greater than or equal to a configured threshold value.

12. The method of claim 11 , further comprising obtaining the correction data based on the geomagnetic data that is greater than or equal to a configured threshold value.

13. The method of claim 8 , further comprising storing the correction data in a memory of the electronic device.
