Augmented reality device for obtaining depth information of object and operating method thereof

An operation method of an augmented reality (AR) device for obtaining depth information of an object in a real world, the operation method comprising:

• obtaining a gaze point by tracking a gaze direction of a user's eye;
• determining a region of interest (ROI) confidence level indicating a degree to which at least one partial region within a field of view (FOV) of the AR device is predicted as an ROI, based on at least one of a moving speed, an acceleration, a fixation time, a fixation number, or a location of the gaze point;
• determining a region surrounding the gaze point corresponding to an object within the at least one partial region at which the ROI confidence level is greater than or equal to a preset threshold value;
• setting the region as an ROI;
• and
• setting a parameter for controlling an operation of a depth sensor of the AR device that is used to obtain depth information of the object within the ROI.

A non-transitory computer-readable storage medium storing instructions which are executable at least one processor of an augmented reality (AR) device to perform a method to obtain depth information of an object in a real world, the method comprising:

• obtaining a gaze point by tracking a gaze direction of a user's eye;
• determining a region of interest (ROI) confidence level indicating a degree to which at least one partial region within a field of view (FOV) of the AR device is predicted as an ROI, based on at least one of a moving speed, an acceleration, a fixation time, a fixation number, or a location of the gaze point;
• determining a region surrounding the gaze point corresponding to an object within the at least one partial region at which the ROI confidence level is greater than or equal to a preset threshold value;
• setting the region as an ROI;
• and
• setting a parameter for controlling an operation of a depth sensor of the AR device that is used to obtain depth information of the object within the ROI.
