Claim 0:
1. A display apparatus communicably connected to an external control apparatus that receives operations performed by an operator, the display apparatus comprising:
a display that displays a pointer in a three-dimensional display area; and
at least one memory and at least one processor and/or at least one circuit which function as:
an obtainer that obtains detection information from the external control apparatus, the detection information including at least one of a two-dimensional directional command or a tilt and/or displacement of the external control apparatus, the two-dimensional directional command being issued on the external control apparatus by the operator; and
a display controller that controls the display such that
when the directional command has not been issued on the external control apparatus, the display apparatus shifts into a first operation state in which a display position of the pointer in the display area is shifted according to the obtained tilt and/or displacement,
when the directional command has been issued on the external control apparatus, the display apparatus shifts into a second operation state in which the display position of the pointer in the display area is shifted based on two coordinate axes in the display area according to the obtained directional command, and
in the second operation state, the two coordinate axes for use in shifting the display position of the pointer are varied according to the tilt of the external control apparatus
wherein the display controller causes the display to display a picked-up real space image in the display area, and
in a case where the display apparatus is in the second operation state, and a virtual object hidden by an object in a real space is present in the display area, the display controller, according to positions of the pointer and the object in the real space, makes the virtual object in the display area appear as silhouette.
