Claim 13:
14. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method for a display apparatus, the 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,
the control method comprising:
obtaining 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
controlling 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,
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,
displaying 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, making the virtual object in the display area to appear as silhouette, according to positions of the pointer and the object in the real space.
