System for, and method of displaying an image of an object responsive to an operator's command
First Claim
1. An image producing/displaying system for producing and displaying an image, comprising:
- a virtual world expressing system which constructs a virtual world including at least one object and environment in which the object exists and produces an image for visually displaying at least part of the virtual world;
an output system for visualizing the image produced by said virtual world expressing system and outputting the image; and
a command input system for inputting a command to said virtual world expressing system,wherein said command input system includes;
imaging means for forming an image of fixed space, andcommand content recognizing means for detecting a movement state of a specific pixel pattern contained in the formed image to extract feature quantity from the movement state and comparing said feature quantity with a predetermined reference to recognize a relevant command so that the command is notified to said virtual world expressing system when the command can be recognized; and
wherein said virtual world expressing system includes;
state setting means for setting states of the object and the environment included in said virtual world, andimage producing means for producing an image of said virtual world on the basis of information set in said state setting means;
said state setting means changing, when the notified command is related to any object, the setting of the state of the object on the basis of the command.

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.

3. A command input system for inputting a command to an information processing unit, comprising:
-
imaging means for forming an image of a predetermined spaced in a serial time manner; means for detecting a movement state of a specific pixel pattern contained in the image formed in a serial time manner by said imaging means; means for extracting feature quantity from the movement state; and means for comparing the feature quantity with a predetermined reference to retrieve a command corresponding to the extracted feature quantity so that when there is a relevant command, the command is received as an input to be notified to said virtual world expressing system. - View Dependent Claims (4)

5. A method of displaying at least one object on a screen where a virtual world is expressed, said method comprising the steps of:
-
determining an action of an operator; causing said object to perform a first behavior when the action of said operator is determined; and causing said object to perform a second behavior when the action of said operator is not determined. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)
