1. An electronic device comprising:
a sensor;
communication circuitry;
a projection assembly;
memory comprising one or more storage media storing instructions; and
at least one processor,
wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
identify, based on an identification of an external electronic device through the communication circuitry, a combination of a first projection area where light of the projection assembly is projected and a second projection area where light of the external electronic device is projected;
display a first portion of a visual object for guiding a reference aspect ratio in the first projection area, wherein the first portion is segmented from the visual object based on a location of the first projection area in the combination of the first projection area and the second projection area, wherein the visual object comprises the first portion and a second portion;
identify a motion of the electronic device based on data of the sensor;
based on the motion of the electronic device identified while displaying the first portion of the visual object, display the second portion of the visual object that is segmented from the visual object based on the location of the first projection area in the combination of the first projection area and the second projection area, that is changed according to the motion; and
based on identifying an aspect ratio of the combination of the first projection area and the second projection area corresponding to the reference aspect ratio, display at least a portion of media content having the reference aspect ratio in the first projection area.
