Method and apparatus for adjusting augmented reality content

1. A method of providing augmented reality (AR) content in an AR device, the method comprising:

monitoring a viewing activity of a user among a plurality of objects;

detecting at least one viewing parameter comprising eye gaze time based on a head movement of the user or an eyeball movement of the user;

determining, based on the eye gaze time, an observation category indicating whether the user is a fast explorer when exploring among the plurality of objects based on a duration of the eye gaze time between each of the plurality of objects;

determining, based on the viewing activity of the user, a viewing time of AR content associated with a next appearing at least one object among the plurality of objects;

determining an amount of the AR content associated with the next appearing at least one object based on the monitored viewing activity of the user and the observation category; and

displaying the AR content of the next appearing at least one object based on the determined amount of the AR content.

2. The method of claim 1 , wherein

the at least one viewing parameter further comprises eye movement determined based on the head movement of the user or the eye ball movement of the user.

3. The method of claim 1 , wherein the monitoring of the viewing activity of the user comprises:

estimating the viewing time using the detected at least one viewing parameter.

4. The method of claim 1 ,

wherein the eye gaze time is divided into a plurality of time instances, and

wherein the determining of the observation category comprises determining the observation category by estimating the viewing time based on the plurality of the time instances.

5. The method of claim 4 , wherein the determining of the viewing time further comprises:

in response to a determination that each of viewing time corresponding to each of the plurality of time instances is one of greater than a predetermined maximum threshold time and less than a predetermined minimum threshold time, determining the amount of the AR content associated with the next appearing at least one object as zero.

6. The method of claim 1 , wherein the determining of the amount of the AR content comprises determining the amount of the AR content in proportion to the length of the eye gaze time.

7. The method of claim 1 , wherein the viewing activity comprises at least one of viewing instances over at least one of a plurality of times instances or a plurality of eye gazes.

8. The method of claim 1 , wherein the monitoring of the viewing activity of the user comprises filtering the viewing activity of the user having a viewing time less than a predetermined minimum threshold time or greater than a predetermined maximum threshold time.

9. The method of claim 8 , wherein the monitoring of the viewing activity of the user further comprises updating at least one of the predetermined minimum threshold time and the predetermined maximum threshold time based on at least one of the observation category, historical viewing activity data, real time viewing activity data, and user-specific profile data.

10. The method of claim 1 , further comprising:

monitoring user data stored in the AR device and location data of the AR device,

wherein the determining of the viewing time of the AR content is performed based on the viewing activity of the user, the monitored user data, and the monitored location data of the AR device.

11. An apparatus for providing augmented reality content, the apparatus comprising:

at least one sensor configured to monitor viewing activity of a user among a plurality of objects;

a processor configured to:

detect at least one viewing parameter comprising eye gaze time based on a head movement of the user or an eyeball movement of the user;

determine, based on the eye gaze time, an observation category indicating whether the user is a fast explorer when exploring among the plurality of objects based on a duration of the eye gaze time between each of the plurality of objects;

determine, based on the viewing activity of the user monitored by the at least one sensor, a viewing time of AR content associated with a next appearing object among the plurality of objects, and

determine an amount of the AR content associated with the next appearing object based on the monitored viewing activity of the user and the observation category; and

a display configured to display the AR textual content of the next appearing object based on the amount of the AR content.

12. The apparatus of claim 11 , wherein the at least one viewing parameter further comprises an eye movement determined based on the head movement of the user or the eye ball movement of the user.

13. The apparatus of claim 11 , wherein the monitoring of the viewing activity of the user comprises:

estimating the viewing time based on the at least one viewing parameter.

14. The apparatus of claim 11 ,

wherein the eye gaze time is divided into a plurality of time instances, and

wherein the determining of the observation category comprises determining the observation category by estimating the viewing time based on the plurality of the time instances.

15. The apparatus of claim 14 , wherein the determining of the viewing time comprises determining the amount of the AR textual content associated with the next appearing object as zero in response to a determination that each of viewing time corresponding to each of the plurality of time instances is greater than a predetermined maximum threshold time or less than a predetermined minimum threshold time.

16. A non-transitory computer readable storage medium having a computer readable program stored therein, the computer readable program, when executed on an AR device, configured to execute instructions to cause the AR device to:

monitor a viewing activity of a user among a plurality of objects;

detect at least one viewing parameter comprising eye gaze time based on a head movement of the user or an eyeball movement of the user;

determine, based on the eye gaze time, an observation category indicating whether the user is a fast explorer when exploring among the plurality of objects based on a duration of the eye gaze time between each of the plurality of objects;

determine, based on the viewing activity of the user, a viewing time of AR content associated with a next appearing object among the plurality of objects;

determine an amount of the AR content associated with the next appearing object based on the viewing activity of the user and the observation category; and

display the AR content of the next appearing object based on the amount of the AR content.
