Abstract
Abstract Vision systems having knowledge of position and attitude can reliably determine what scenes are being addressed by the system. Real images of the scene can then be augmented with computer generated information which relates to the known scene. A determination of position and attitude of the device identifies which scene is being addressed. A computer recalls information regarding the scene and generates imagery according to that recalled information. The computer generated imagery is then combined with an image of the scene to form an augmented image which is presented to the user aligned to the viewing direction of the device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
141 words
An apparatus for viewing a scene comprising: a camera; a position determining means; an attitude determining means; a computer; and a display, the camera having a lens and transducer for converting an optical image of a scene into an electronic signal, the lens having a symmetry axis which defines a pointing direction of the camera; the position determining means being operable for determining the position of the camera; the attitude determining means being operable for determining the attitude of the camera pointing direction; the computer operable for receiving an image signal from the camera and further operable for generating images relating to the position and attitude of the apparatus and operable for combining those images into a composite image and transmitting a composite image signal to a; display having a normal direction aligned with and colinear with the camera pointing direction.
Claim 2
Independent Claim
141 words
An apparatus for viewing a scene comprising: a camera; a position determining means; an attitude determining means; a computer; and a display, the camera having a lens and transducer for converting an optical image of a scene into an electronic signal, the lens having a symmetry axis which defines a pointing direction of the camera; the position determining means being operable for determining the position of the camera; the attitude determining means being operable for determining the attitude of the camera pointing direction; the computer operable for receiving an image signal from the camera and further operable for generating images relating to the position and attitude of the apparatus and operable for combining those images into a composite image and transmitting a composite image signal to a; display having a normal direction aligned with and colinear with the camera pointing direction.
Claim 3
Dependent Claim
25 words
An apparatus of claim 1, said position determining means being further operable for determining the position of the camera with respect to an arbitrary reference.
Claim 4
Dependent Claim
27 words
An apparatus of claim 1, said position determining means being further operable for determining the global position of the camera as determined by a global positioning system.
Claim 5
Dependent Claim
29 words
An apparatus of claim 1, said attitude determining means being an electronic compass operable for measuring the pointing direction of the camera over a 4-pi steradian solid angle range.
Claim 6
Dependent Claim
36 words
An apparatus of claim 1, wherein said generating images relating to the position and attitude further comprises: recalling from a memory location associated with said position and attitude determinations information relating to the scene being addressed.
