System and method for performing constellation game using virtual reality

A system for performing a constellation game using virtual reality, the system comprising:

• a head mounted display (HMD) configured to be worn on a user's head;
• a user gaze direction detector configured to detect a direction that the user gazes;
• a wearable input device configured to be worn on the user's body, the wearable input device comprising a game start button configured to receive a game start command, the wearable input device configured to select a constellation and connect dots on an outline of the constellation to each other;
• and
• a controller configured to:
• in response to the game start command being received, control the user gaze direction detector to detect a user gaze direction and provide to the HMD a celestial image according to the user gaze direction;
• in response to any one constellation being selected on the celestial image by the wearable input device, provide an image of dots on an outline of the selected constellation to the HMD;
• and
• in response to the dots on the outline being connected to each other by the wearable input device, provide to the HMD an image of the selected constellation, a mixed image obtained by inserting an illustration into the image of the constellation, and storytelling information on the constellation.
