Appeal No. 1999-2698
Application 08/560,108
prestored in a computer spatial model of an object space
within which images of virtual objects are integrated with
images of the real objects acquired from a head mounted
camera.
It is specifically noted by Appellant that Deering deals 22
with the image lag problem by using a forward prediction, such
as a linear interpolation or higher order interpolators based
on Kalman filtering. This mode is entirely different from
Appellant's mode of lag reduction which reduces the effect of
latency by concentrating the computational power of the image
processor on the moving virtual objects and substituting real
objects for the stationary parts of the virtual environment
which can be imaged by cameras mounted on the viewer's head.
In the rejection the Examiner admits that Bajura does23
not explicitly disclose that the graphic image signal is a
prestored graphic image signal, and asserts that it is well
known in the art to generate a prestored virtual image signal
