1. A head mounted display (HMD), comprising: a display unit configured to display visual information; a position sensing unit configured to sense a position of the HMD; a camera unit configured to sense at least one object positioned at a front of the HMD; and a processor configured to control the display unit, the position sensing unit, and the camera unit, wherein the processor is further configured to: obtain position information of the HMD, generate a first virtual map indicating a virtual object corresponding to the at least one object positioned at the front of the HMD, based on the position information of the HMD, and display the first virtual map in a first slope or a second slope while the HMD is worn by a user, wherein the first virtual map corresponds to a curved map which is displayed on top of a first object and wherein a degree of a slope of the curved map increases as a distance from the HMD increases, wherein the first slope corresponds to a slope when a destination is positioned within a predetermined distance range from the HMD, and the second slope corresponds to a slope when the destination is positioned outside the predetermined distance range from the HMD, and wherein the first slope is steeper than the second slope.
