Claim 6:
7. A virtual object display device, comprising:
a display;
a display control device configured to perform display control of the display, the display control device including:
a coordinate system calculation unit configured to detect a movement amount and a rotation amount of the virtual object display device in a real world, and use an inertial coordinate system in which a coordinate origin thereof follows movement of the virtual object display device and an effective field of view of the display is rotated therein in accordance with rotation of the virtual object display device so as to define an arrangement position of an inertial coordinate system virtual object; and
a display control unit configured to, when the inertial coordinate system virtual object is included in the effective field of view of the display, display the inertial coordinate system virtual object within the effective field of view; and

an acceleration sensor connected to the display control device to measure acceleration of the virtual object display device, wherein
the coordinate system calculation unit computes a smoothed position obtained by smoothing positions of the virtual object display device which have been calculated based on signals from the acceleration sensor so as to reset an origin of the inertial coordinate system on the smoothed position.
