## Abstract

An electronic device is provided. The electronic device includes a first sensor, a memory, a display, and a processor. The processor is configured to identify an ambient illuminance of the electronic device using the first sensor, when the identified illuminance is within a first illuminance range, designate a position where content stored in the memory is to be displayed in at least part of a first display region corresponding to a first field of view (FOV), and when the identified illuminance is within a second illuminance range, designate the position where the content is to be displayed in at least part of a second display region corresponding to a second FOV broader than the first FOV.

## Claims

### Claim 1

An electronic device, comprising:

a memory;
a display; and
a processor configured to:
identify an ambient illuminance of the electronic device using the first sensor,
when the identified illuminance is within a first illuminance range, designate a position where content stored in the memory is to be displayed in at least part of a first display region corresponding to a first field of view (FOV), and
when the identified illuminance is within a second illuminance range, designate the position where the content is to be displayed in at least part of a second display region corresponding to a second FOV broader than the first FOV.

### Claim 2 (depends on 1)

The electronic device of claim 1, wherein the processor is further configured to:
identify a request to display the content,
upon identifying the content display request, identify the position of display of the content through the display, and
display the content in the first display region or the second display region based on the identified position.

### Claim 3 (depends on 1)

The electronic device of claim 1, wherein the second illuminance range includes a range corresponding to an illuminance higher than the first illuminance range.

### Claim 4 (depends on 2)

The electronic device of claim 2, wherein the processor is further configured to adjust at least one of a position or size of the content to allow a position of a virtual image corresponding to the content to be adjusted based on the identified illuminance.

### Claim 5 (depends on 4)

The electronic device of claim 4, wherein the processor is further configured to adjust the position of the virtual image corresponding to the content by adjusting a distance between an image for left eye corresponding to the content and an image for right eye corresponding to the content based on the identified illuminance.

### Claim 6 (depends on 4)

The electronic device of claim 4, wherein the processor is further configured to,
when the identified illuminance is lower than a designated illuminance, adjust the position of the virtual image to allow the content to be displayed in the first display region and,
when the identified illuminance is higher than the designated illuminance, adjust the position of the virtual image to allow the content to be displayed in the second display region.

### Claim 7 (depends on 4)

The electronic device of claim 4, wherein the processor is further configured to maintain the position of the virtual image corresponding to the content when the identified illuminance is within a range corresponding to the designated illuminance.

### Claim 8 (depends on 1)

The electronic device of claim 1, further comprising a second sensor,
wherein the processor is further configured to:
identify a speed of the electronic device using the second sensor,
when the identified speed is within a first speed range, designate the position where the content stored in the memory is to be displayed in at least part of a third display region and,
when the identified illuminance is within a second speed range, designate the position where the content is to be displayed in at least part of a fourth display region having a narrower FOV than the third display region.

### Claim 9 (depends on 8)

The electronic device of claim 8, wherein the second speed range corresponds to a speed higher than the first speed range.

### Claim 10

An electronic device, comprising:
a sensor configured to detect a state of the electronic device;
a memory;

a processor configured to:
identify the state of the electronic device using the sensor,
when a sensor value indicating the identified state of the electronic device is within a first range, designate a position where content stored in the memory is to be displayed in at least part of a first display region corresponding to a first field of view (FOV), and
when the sensor value falls within a second range, designate the position where the content is to be displayed in at least part of a second display region corresponding to a second FOV broader than the first FOV.
