Portable device and method of controlling therefor

A portable device comprising a first body at the center of the portable device, a second body positioned at one side of the first body and a third body positioned at another side of the first body:

• a display unit configured to display visual information on at least one of a first area of the first body, a second area of the second body and a third area of the third body;
• a first sensor unit configured to detect at least one of a first folding angle between the first body and the second body and a second folding angle between the first body and the third body;
• a second sensor unit configured to detect a state that a rear side of the second body is contacted with a different real object;
• and
• a processor configured to control the display unit, the first sensor unit and the second sensor unit,
• wherein the processor is further configured to:
• set a first mode based on the first folding angle and the second folding angle,
• display a first application in the first mode,
• detect change of the first folding angle and the second folding angle in the first mode,
• switch the first mode to a second mode when the changed first folding angle is equal to or greater than a first threshold angle, the changed second angle being less than a second threshold angle and the rear side of the second body is in the state of being contacted with the different real object,
• wherein the second mode corresponds to a mode displaying the first application on the first area and displaying a second application related to a first object contained in the first application on the second area.
