Patent ID: 7002551

Claim:
An optical see-through imaging apparatus having variable magnification for producing an augmented image from a real scene and a computer generated image, the apparatus comprising: a. a sensor suite for precise measurement of a user's current orientation; b. a render module connected with the sensor suite for receiving a sensor suite output comprising the user's current orientation for use in producing the computer generated image of an object to combine with the real scene; c. a position measuring system connected with the render module for providing a position estimation for producing the computer generated image of the object to combine with the real scene; d. a database connected with the render module for providing data for producing the computer generated image of the object to combine with the real scene; and e. an optical display connected with the render module configured to receive an optical view of the real scene, and for combining the optical view of the real scene with the computer generated image of the object from the render module to produce a display based on the user's current position and orientation for a user to view.
