Abstract: Multiple imaging apparatuses 12a and 12b are arranged to capture images of a space in which an HMD 18 is found. The images captured by the imaging apparatuses are analyzed individually to acquire position and posture information regarding the HMD 18 in each of camera coordinate systems of the apparatuses. The position and posture information is aggregated to one information processing apparatus and transformed thereby into information in a world coordinate system independent of the imaging apparatuses. Relative relations between the positions and postures of the imaging apparatuses are acquired by making use of a period during which the HMD 18 is in a region 186 where the fields of view of the imaging apparatuses overlap with each other. The relative relations are used as the basis for acquiring parameters for transforming coordinates between the imaging apparatuses.

Abstract: As a user guide, the state of overlooking a real space including an imaging device and a user is presented by one of two images: an image in reference to the position of the imaging device, or an image in reference to the user's direction. In both images, a rectangle indicative of the imaging device and a circle representative of the user are presented in a manner reflecting the actual positional relations and directions involved. Also presented are an area denoting a play area in the horizontal direction determined by a camera angle of view for example, and an arrow pointing to the direction in which the user is to move.
