A method of providing a 3D information service at a user terminal includes: receiving a first request of a user for displaying information; and displaying information elements, which have different depths along the Z axis orthogonal to a screen (XY plane), by rotating the information elements about any one of the X axis and the Y axis, where the rotational axis of each of the information elements is set at different points on the YZ plane or the XZ plane. According to certain embodiments of the invention, the information elements on a screen may be shown as planar elements in a still screen for greater legibility, but when the information elements are in motion, such as for changing the screen or moving a content element, the motion is provided with differing speeds according to depth, thereby providing a sense of spatial perception unique to 3-dimensional images.
