Classification: CPC G  H | IPC G

Claim 5:
6. 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 coordinate system information storage unit configured to store a front direction of the inertial coordinate system, wherein
the coordinate system information storage unit stores therein a direction that was set in the virtual object display device as the front direction at a last time, and
when a main power of the virtual object display device is turned on, the coordinate system calculation unit resets the front direction stored in the coordinate system information storage unit as the front direction of the inertial coordinate system.
