ABSTRACT:
An image producing/displaying apparatus capable of inputting a command for changing a state of an object regardless of a form of the object includes a virtual world expressing system for constructing a virtual world including at least one object and environment in which the object exists and producing an image for visually displaying at least part of the virtual world, an output system for visualizing the image produced by the virtual world expressing system and outputting the image, and a command input system for inputting a command to the virtual world expressing system. The command input system detects a movement state of a specific pixel pattern contained in an image formed by an imaging device and extracts feature quantity from the movement state to recognize the command so that the command is notified to the virtual world expressing system.
