PROBLEM TO BE SOLVED: To provide an intuitive spatial user interface by which devices such as a sensor and a display device are not required to be mounted on a body of a user and the need for a high resolution display device is also eliminated. SOLUTION: This display device is provided with a 3-dimensional storage means 2 for storing a 3-dimensional virtual world, a movable display device 1 whose position and direction are variable, a projection means 4 that projects the 3-dimensional virtual world stored in the 3-dimensional storage means 2 into a 2-dimensional image, and visual point projecting face decision means 3 that decides a visual point position and a position and a direction of the projection face at the projection by the projection means 4, depending on the position and the direction of the movable display device 1, and the 2-dimensional image obtained by projecting the decided visual point position and the position and the direction of the projection face is displayed on the movable display device 1 to the user. |
