Electric device and operation method thereof

Disclosed are an electronic device and a method of operating the same. According to embodiments of the present invention, the electronic device includes: a wireless communication unit to access a head-mount display which displays an augmented reality image; a controller to sequentially acquire surrounding images using a camera, extract a plurality of feature points from the acquired image, detect a moving path of the extracted feature points according to a result acquired by matching the same feature points in the acquired image, and create a three dimensional (3D) map. In addition, the controller can control the wireless communication unit to transmit an augmented image, which is acquired by synthesizing virtual objects allowing a user input in match with the position and the direction of the camera based on the created map, to the accessed head-mounted display.
