Electronic device for outputting image based on result of predicting future eye position and method performed by the same

One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of an electronic device individually or collectively, cause the electronic device to perform operations, the operations comprising:

• obtaining, by the electronic device, position information of a target part corresponding to a past time point, and position information of the target part corresponding to a reference time point, from an image that includes a facial region of a viewer and is input through a camera;
• obtaining, by the electronic device, position change information of the target part corresponding to the reference time point, based on the position information of the target part corresponding to the past time point, and the position information of the target part corresponding to the reference time point;
• predicting, by the electronic device, a future velocity of the target part based on the position change information of the target part corresponding to the reference time point, and position change information of the target part corresponding to the past time point;
• obtaining, by the electronic device, velocity change information of the target part corresponding to the reference time point, based on the position change information of the target part corresponding to the reference time point, and the position change information of the target part corresponding to the past time point;
• predicting, by the electronic device, a future acceleration of the target part based on the velocity change information of the target part corresponding to the reference time point, velocity change information of the target part corresponding to the past time point, and a movement state of the viewer, the movement state of the viewer being one among the viewer being stationary and the viewer moving;
• predicting, by the electronic device, future positions of eyes corresponding to a target time point based on the future velocity and the future acceleration;
• and
• outputting, by the electronic device, an image based on the future positions of the eyes corresponding to the target time point.
