Embodiment Construction

[0021] Hereinafter, an exemplary embodiment of the present invention will be described in detail in accordance with the drawings.

[0022] figure 1 It is a figure which shows the embodiment of an example of this invention. The position and orientation sensor controller 103, the position and orientation sensor 104, the joystick 105, the memories 106 and 107, and the HMD 108 are connected to a central processing unit (CPU) 101 through a bus 102. The joystick 105 is a control lever and acquires a value corresponding to the direction of the inclination of the lever. The joystick 105 may be replaced with, for example, a keyboard or an input device for video games. The memory 106 may be the same as the memory 107. The position and orientation sensor 104 is connected to the position and orientation sensor controller 103. The position and orientation sensor controller 103 is an interface for providing the position and orientation of the position and orientation sensor 104. The position ...

Abstract

An actual-size observation mode in which an observer performs observation by being immersed in a virtual three-dimensional space in an actual size and a reduced-size observation mode in which the observer performs observation by reducing a virtual three-dimensional space computer graphics image are provided. A virtual reality presentation device includes an observation mode setting unit for setting, as an observation mode, the actual-size observation mode or the reduced-size observation mode; a position and orientation information acquisition unit for acquiring position and orientation information of the observer; and a generation unit for generating a computer graphics image from computer graphics data representing the virtual three-dimensional space in accordance with the set observation mode and the position and orientation information.

Description

Technical field [0001] The present invention relates to a virtual reality presentation device and an information processing method for providing a virtual three-dimensional space (3D) experience. Background technique [0002] Virtual reality (VR) presentation devices are already available. Virtual reality presentation devices include, for example, image displays, such as head-mounted displays (HMD), position and orientation detection devices, such as position and orientation sensors, for detecting the position and orientation of the observer's viewpoint, and computer graphics (CG) Image generating device. [0003] For example, a magnetic position and orientation sensor is used as a position and orientation detection device. The magnetic position and orientation sensor is installed in the HMD worn by the observer, so that the position and orientation of the observer's head can be detected. The magnetic position and orientation sensor detects the relative position and orientation b...
