Wearable device for identifying area for displaying image and method thereof

A method of a wearable device, wherein the wearable device comprises one or more cameras, and at least one display, comprising:

• obtaining a real space image using the one or more cameras;
• displaying a virtual environment on the at least one display;
• while displaying the virtual environment, identifying an external object included in the real space image;
• based on identifying the external object, determining a first area in the virtual environment for displaying a portion of the real space image corresponding to the identified external object;
• concurrently displaying the virtual environment and the portion of the real space image corresponding to the external object, wherein the portion of the real space image is displayed at the determined first area with a first transparency;
• tracking movement of the external object from the real space image;
• based on the tracked movement of the external object, determining a second area for displaying a portion of the real space image corresponding to the moved external object in the virtual environment;
• and
• based on the determined second area, concurrently displaying the virtual environment and the portion of the real space image corresponding to the moved external object, wherein the portion of the real space image is displayed at the determined second area with the first transparency.

A non-transitory computer readable storage medium storing instructions, wherein the instructions, when executed by a wearable device comprising one or more cameras, and at least one display, cause the wearable device to:

• obtain a real space image using the one or more cameras;
• display a virtual environment on the at least one display;
• while displaying the virtual environment on the at least one display, detect a portion of the real space image corresponding to an external object;
• and
• in response to the detection, gradually increase a transparency of a portion of the virtual environment displayed on the at least one display such that the portion of the real space image corresponding to the external object gradually appears within the portion of the virtual environment.
