Electronic apparatus and method for controlling the same

An electronic apparatus comprising:

• at least one memory and at least one processor which function as:
• a line-of-sight detection unit configured to detect a user's gaze position to a display screen;
• an orientation detection unit configured to detect an orientation of a body including the display screen;
• and
• a control unit configured to execute calibration data acquisition processing for gaze position calibration,
• wherein, in the calibration data acquisition processing, the control unit controls the line-of-sight detection unit to detect user's gaze positions for a plurality of different positions respectively, and
• wherein, in a case where a first orientation, which is an orientation of the body when a user's gaze position for a first position among the plurality of positions is detected, is different from an orientation of the body when a user's gaze position for a position different from the first position among the plurality of positions is detected during the calibration data acquisition processing, the control unit performs the control to display a warning for prompting the user to return a changed orientation of the body to the first orientation.
