Classification: CPC G  H | IPC G

Claim 1:
2. 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

a motion measurement sensor connected to the display control device to measure the movement amount and the rotation amount of the virtual object display device, wherein
the coordinate system calculation unit performs a smoothing process with respect to directions of the virtual object display device which have been calculated based on signals from the motion measurement sensor so as to reset a front direction of the inertial coordinate system.
