1. A method for providing position information based on a 10-20 system, which is performed by a device, the method comprising:
obtaining a head image of an object;
receiving, from a user, at least four reference points based on the head image, by receiving front, back, left, and right reference points of a head, which are included in the head image;
calculating central coordinates of the head image, based on the at least four reference points;
providing the position information based on the 10-20 system, based on the central coordinates; and
deriving a coordinate system of the 10-20 system by using distance information on a first connection line, which is obtained by linking the front reference point of the head to the back reference point of the head based on the central coordinates, and distance information on a second connection line which is obtained by linking the left reference point of the head to the right reference point of the head based on the central coordinates.
