Abstract

Provided are wearable glasses including a display and a method of operating the same. The wearable glasses include: a display configured to display an image; a sensor configured to acquire wear state information representing a state in which a user currently wears the wearable glasses, while the image is being displayed on the display; and a processor configured to determine an inclination of the wearable glasses with respect to the user based on the acquired wear state information, and to adjust, based on the determined inclination, the image that is displayed on the display.

First claim

What is claimed is:

1. Wearable glasses comprising:
a display configured to display an image;
a sensor configured to acquire wear state information representing a state in which a user currently wears the wearable glasses, while the image is being displayed on the display, the wear state information including a reflection image which is formed by reflection of the image on an eye of the user; and
a processor configured to determine an inclination of the wearable glasses with respect to the user based on at least one of a size and a shape of the reflection image, and to adjust, based on the determined inclination, the image that is displayed on the display.

2. The wearable glasses of claim 1 , wherein:
the sensor is configured to acquire the wear state information including information about a body part of the user; and
the processor is configured to determine the inclination of the wearable glasses with respect to the user by comparing the acquired wear state information with predetermined reference wear state information.

3. The wearable glasses of claim 2 , wherein:
the sensor is configured to acquire the wear state information including an image of the body part; and
the processor is configured to detect an area corresponding to the body part from the image of the body part, to acquire a property value from the detected area, and to compare the acquired property value with a reference value included in the reference wear state information in order to determine the inclination.

4. The wearable glasses of claim 1 , wherein:
the acquired wear state information comprises an eye image of the eye of the user who is wearing the wearable glasses; and
the processor is configured to acquire at least one value from among a length of a major axis of the eye, a length of a minor axis of the eye, an angle of the major axis of the eye, an angle of the minor axis of the eye, and a location value of an iris of the user from the eye image, to compare the acquired at least one value with at least one predetermined reference value, and to determine the inclination based on a result of the comparison.

5. The wearable glasses of claim 1 , wherein:
the display is configured to display a test image;
the sensor is configured to acquire the wear state information including an eye image of the eye of the user on which the test image is reflected; and
the processor is configured to detect an area corresponding to the eye of the user from the eye image, to obtain the reflection image of the test image within the detected area corresponding to the eye, to compare the at least one of the size and the shape of the obtained reflection image with predetermined reference wear state information, and to determine the inclination based on a result of the comparison.

6. The wearable glasses of claim 1 , wherein the sensor is configured to obtain a state value representing a movement state of the wearable glasses and to acquire the wear state information when the obtained state value is equal to or greater than a predetermined value.

7. The wearable glasses of claim 1 , wherein:
the processor is configured to determine whether the determined inclination is equal to or greater than a predetermined value;
when the processor determines that the determined inclination is less than the predetermined value, the processor is configured to control the display to display the adjusted image obtained based on the determined inclination; and
when the processor determines that the determined inclination is equal to or greater than the predetermined value, the processor is configured to control the display to display an image informing the user to adjust the wearable glasses.

8. A method of displaying an image via wearable glasses, the method comprising:
displaying, on a display of the wearable glasses, an image;
acquiring wear state information representing a state in which a user currently wears the wearable glasses, the wear state information including a reflection image which is formed by reflection of the image on an eye of the user;
determining an inclination of the wearable glasses with respect to the user based on at least one of a size and a shape of the reflection image; and
adjusting, based on the determined inclination, the image that is displayed on the display.

9. The method of claim 8 , wherein:
the acquiring the wear state information comprises acquiring the wear state information including information about a body part of the user; and
the determining the inclination comprises determining the inclination of the wearable glasses with respect to the user by comparing the acquired wear state information with predetermined reference wear state information.

10. The method of claim 9 , wherein:
the acquiring the wear state information comprises acquiring the wear state information including an image of the body part; and
the determining the inclination comprises:
detecting an area corresponding to the body part from the image of the body part,
acquiring a property value from the detected area, and
comparing the acquired property value with a reference value included in the predetermined reference wear state information in order to determine the inclination.

11. The method of claim 8 , wherein:
the wear state information comprises an eye image of the eye of the user who is wearing the wearable glasses; and
the determining the inclination comprises:
acquiring at least one value from among a length of a major axis of the eye, a length of a minor axis of the eye, an angle of the major axis of the eye, an angle of the minor axis of the eye, and a location value of an iris of the user from the eye image,
comparing the acquired at least one value with at least one predetermined reference value, and
determining the inclination based on a result of the comparing.

12. The method of claim 8 , wherein:
the displaying the image comprises displaying a test image;
the acquiring the wear state information comprises acquiring the wear state information including an eye image of the eye of the user on which the test image is reflected; and
the determining the inclination comprises:
detecting an area corresponding to the eye of the user from the eye image,
obtaining the reflection image of the test image within the detected area corresponding to the eye,
comparing the at least one of the size and the shape of the reflection image with predetermined reference wear state information, and
determining the inclination based on a result of the comparing.

13. The method of claim 8 , wherein the acquiring the wear state information comprises:
obtaining a state value representing a movement state of the wearable glasses; and
acquiring the wear state information when the obtained state value is equal to or greater than a predetermined value.

14. The method of claim 8 , wherein the adjusting the image comprises:
determining whether the determined inclination is equal to or greater than a predetermined value;
if the determined inclination is equal to or greater than the predetermined value according to the determining, displaying an image informing the user to adjust the wearable glasses; and
if the determined inclination is less than the predetermined value according to the determining, adjusting the image that is displayed on the display, based on the determined inclination.

15. A non-transitory computer-readable storage medium having embodied thereon at least one program including commands for performing a method of displaying an image via wearable glasses, wherein the method comprises:
displaying an image that is
