Claim One:
1. A mobile terminal comprising: a touch screen configured to implement stereoscopic vision; a controller configured to: cause the touch screen to display a plurality of stereoscopic graphic objects corresponding to a plurality of items by implementing binocular parallax such that a depth level of each of the plurality of displayed stereoscopic graphic objects is controlled based on a user's usage pattern with respect to a corresponding one of the plurality of items, wherein at least two of the plurality of displayed stereoscopic graphic objects have different depth levels, and wherein the usage pattern includes at least frequency of use, usage recency, or status of a bookmark setting; specify a reference range based on a depth level of a particular stereoscopic graphic object and search at least one item having a usage pattern corresponding to a depth level that is within the specified reference range among the plurality of items in response to a touch input for selecting the particular stereoscopic graphic object from among the plurality of displayed stereoscopic graphic objects, wherein a minimum value of the reference range is less than or equal to the depth level of the selected particular stereoscopic graphic object, and a maximum value of the reference range is greater than or equal to the depth level of the selected particular stereoscopic graphic object; and control the touch screen such that a three-dimensional (3D) display characteristic of the selected particular stereoscopic graphic object and a 3D display characteristic of at least one stereoscopic graphic object corresponding to the searched at least one item are same such that the 3D display characteristic of the selected particular stereoscopic graphic object and the at least one stereoscopic graphic object is different from 3D display characteristics of remaining stereoscopic graphic objects among the plurality of displayed stereoscopic graphic objects having depth levels that are not within the specified reference range; and a memory configured to store the user's usage pattern, wherein each of the at least two of the plurality of displayed stereoscopic graphic objects is associated with a different usage pattern of a corresponding one of the plurality of items such that the at least two of the plurality of displayed stereoscopic graphic objects have different depth levels prior to receiving the touch input for selecting the particular stereoscopic graphic object.
