MIXED-REALITY PRESENTATION SYSTEM AND CONTROL METHOD THEREFOR
First Claim
1. A control method for a mixed-reality presentation system that presents an observer with a mixed reality by superimposing a virtual object rendered according to a position and orientation of a viewpoint of said observer onto physical space or onto a sensed image of physical space, said control method comprising:
- a measuring step of measuring said position and orientation of a viewpoint of said observer;
a virtual object detection step of detecting a virtual object included in a view volume based on said position and orientation of a viewpoint obtained in said measuring step; and
an adding step of adding a virtual object for manipulation to virtual objects to be rendered that satisfy certain display conditions from among virtual objects included in said view volume.

Abstract
In a mixed-reality presentation system, a handler for manipulating a virtual object is displayed as a virtual object. Then, manipulation of the handler by the hand(s) of an observer is detected as manipulation of the virtual object associated with the handler, and those detection results are reflected in a display of the manipulated virtual object. By dynamically changing virtual objects displaying the handler according to the size of the virtual objects displayed in a view volume of the observer presented with a mixed reality space, the observer can select a desired virtual object with ease.

8. A mixed-reality presentation system that presents an observer with a mixed reality by superimposing a virtual object rendered according to a position and orientation of a viewpoint of said observer onto physical space or onto a sensed image of physical space, said mixed-reality presentation system comprising:
-
a measuring unit adapted to measure said position and orientation of a viewpoint of said observer; a virtual object detection unit adapted to detect a virtual object included in a view volume based on said position and orientation of a viewpoint obtained by said measuring unit; and an adding unit adapted to add a virtual object for manipulation to virtual objects to be rendered that satisfy certain display conditions from among virtual objects included in said view volume. - View Dependent Claims (9)
