Appeal No. 1999-1344
Application 08/364,718
sensing head attitude, not head position. Brief at page 9.
Finally, Appellant asserts that neither Lewis nor Beckman
enables the signal processing carried out by the claimed
signal processor. Brief at page 9.
The Examiner maintains that Lewis teaches an eye monitor,
position monitor, signal processor and control. Examiner's
Answer at page 3. However, the Examiner looks to the Beckman
reference for the teaching of head translational movement and
asserts that it would have been obvious to one having ordinary
skill in the art to utilize the Beckman method for sensing
both the translational and angular movements of the traveler's
head in the monitoring system taught by Lewis to provide an
accurate virtual image of a scene surrounding a vehicle
because a virtual reality control system would sense the
position and orientation of the traveler's head and adjust the
projection parameters to maintain the illusion that the
traveler is immersed in a real scene. Examiner's Answer at
page 4.
We find that Lewis enables a means of coordinating the
movement or control of a remote sensor with the movement of
the remote observer's head or eyes. See Lewis, column 1,
