Abstract:
1. An information processing method for synthesizing a pointer image in a displayed image, said method comprising the steps of: detecting a position and an orientation of a viewpoint upon which the displayed image is based; inputting an instruction of an operator for operating a position of the pointer image; changing a pointer coordinate system in response to an instruction of the operator, wherein the pointer coordinate system is changed to a pointer coordinate system that is based on the detected viewpoint; obtaining a designated direction in the pointer coordinate system in accordance with the instruction of the operator for operating the position of the pointer image; and synthesizing the pointer image in the displayed image, wherein the pointer image is synthesized based on the designated direction, wherein a position of said pointer coordinate system is linked to said position of the viewpoint, and orientation of said pointer coordinate system is not linked to said orientation of the viewpoint.
