CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is a Continuation Application of U.S. patent application Ser. No. 16/388,059, filed on Apr. 18, 2019, and is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application Serial No. 10-2018-0057208, filed on May 18, 2018, in the Korean Intellectual Property Office, the entire disclosures of which are incorporated herein by reference. 
    
    
     BACKGROUND 
     1. Field 
     The present disclosure relates generally to electronic devices that adjust the position of content displayed on a display and methods for operating the same. 
     2. Description of Related Art 
     As electronic devices are highly integrated, and high-speed, high-volume wireless communication technology advances, electronic devices come equipped with various functions. For example, electronic devices come with integrated functionality, including entertainment functions, such as playing video games, multimedia functions, replaying music/videos, communication and security functions for mobile banking, and scheduling or e-wallet functions. 
     Advancing display and battery performance has led to the development of more compact and portable electronic devices. For example, head-mounted or other various wearable electronic devices are being introduced. 
     Recently, electronic devices are providing more diversified services and additional functions. Also being developed is a diversity of applications runnable on portable devices. Head-mounted devices, wearable devices, or other various portable electronic devices are coming into use to meet user demand. 
     A head-mounted portable device may display augmented reality (AR) images. A head-mounted portable device may output an AR image in an unchanged display region regardless of ambient illuminance or movement speeds. 
     The user&#39;s view angle may be varied by ambient illuminance or movement speeds due to differences in features between the periphery and center of the retina. For example, the user may need to shift their gaze to a display region where an image is output as ambient illuminance or movement speed varies. When no change is made to the image due to ambient illuminance or movement speed, the user who steadily gazes at the AR image may suffer from fatigue, pupil damage, or other safety issues due to a delay in gaze shift. 
     SUMMARY

Further, the processor  320  may output the content with a shorter focal length than when the illuminance is lower. When the illuminance is lower than the designated illuminance, the user&#39;s field-of-view may be narrow and, thus, the processor  320  may adjust the position of the output of content so that the content is output in the display region corresponding to the narrow field-of-view. Further, the processor  320  may output the content with a longer focal length than when the illuminance is higher. 
     The processor  320  may identify the ambient illuminance of the electronic device  301  using the illuminance sensor  312 . The processor  320  may display content in the display region corresponding to the range that includes the identified illuminance based on the identified illuminance. When the identified illuminance is within a first illuminance range, the processor  320  may designate the position of display of the content as at least part of a first display region. When the identified illuminance is within a second illuminance range, the processor  320  may designate the position of display of the content as at least part of a second display region. The first display region and the second display region may mean regions included in the display  360 . The first display region and the second display region may mean regions when an image and/or object is displayed using augmented reality technology. The first display region and the second display region may have different view angles (or fields of view) and/or focal lengths.

     When the speed is lower than a designated speed, the user&#39;s FOV may be wide and, thus, the processor  320  may adjust the position of the output of content so that the content is output in the display region corresponding to the wide FOV. Further, the processor  320  may output the content with a shorter focal length than when the speed is higher. When the speed is higher than the designated speed, the user&#39;s FOV may be narrow and, thus, the processor  320  may adjust the position of the output of content so that the content is output in the display region corresponding to the narrow FOV. Further, the processor  320  may output the content with a longer focal length than when the speed is lower.

The third display region and the fourth display region may mean regions included in the display  360 . The third display region and the fourth display region may mean regions when an image and/or object is displayed using augmented reality technology. The third display region and the fourth display region may have different view angles (or FOVs) and/or focal lengths. When the second speed range corresponds to a speed higher than the first speed range, the third display region may correspond to a third FOV, and the fourth display region may correspond to a fourth FOV narrower than the third FOV and having a focal length longer than the third FOV. The first display region and the third display region may be the same as or different from each other. The second display region and the fourth display region may be the same as or different from each other.

The processor  320  may change the position of the virtual image corresponding to the content to the inside of the user (e.g., closer to the center axis of the user&#39;s FOV). In order to change the position of the virtual image corresponding to the content, the processor  320  may adjust the position and/or size of the content displayed on the display  360 . The processor  320  may change the position of content displayed through the display  360  to an inside region. The processor  320  may decrease the distance between the image for the left eye corresponding to the content and the image for the right eye corresponding to the content.

The processor  320  may change the position of the virtual image corresponding to the content to the outside of the user (e.g., away from the center axis of the user&#39;s FOV). In order to change the position of the virtual image corresponding to the content, the processor  320  may adjust the position and/or size of the content displayed on the display  360 . The processor  320  may change the position of content displayed through the display  360  to an outside region. The processor  320  may increase the distance between the image for the left eye corresponding to the content and the image for the right eye corresponding to the content.

     The processor  320  may adjust the distance L between the first image  1110  (e.g., an image for the left eye) and the second image  1120  (e.g., an image for the right eye) corresponding to the content displayed through the display  360  based on at least one of the illuminance and speed of the electronic device  301 . The processor  320  may adjust the position (or depth) of the virtual image corresponding to the content by adjusting the distance L between the first image  1110  and the second image  1120 . The processor  320  may move the first image  1110  to the left and the second image  1120  to the right, thus increasing the distance L between the first image  1110  and the second image  1120 . The processor  320  may move the first image  1110  to the right and the second image  1120  to the left, thus reducing the distance between the first image  1110  and the second image  1120 . The processor  320  may adjust the position or depth of the virtual image corresponding to the content by adjusting the distance between the first image  1110  and the second image  1120 . In other words, the processor  320  may adjust the position or depth of the virtual image using binocular parallax for the first image  1110  and the second image  1120 .
