1. An augmented reality (AR) device for obtaining depth information of an object, the AR device comprising:
a gaze tracking sensor configured to obtain a gaze point by tracking a gaze direction of a user's eye;
a depth sensor configured to obtain depth information of the object;
a memory storing one or more instructions; and
at least one processor configured to execute the one or more instructions to:
determine 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;
determine 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;
set the region as an ROI; and
set a parameter for controlling an operation of the depth sensor to obtain depth information of the object within the ROI.
