Application 08/364,718
This is a decision on appeal under 35 U.S.C. § 134 from
the final rejection of claims 1-8, all the claims pending in
the application.
The instant invention discloses an eye tracking method
and apparatus that provides a new way to monitor the eye with
respect to more than one coordinate system. An eye attitude
monitor is combined with a head translatory position monitor
in order to relate the eye translatory position as well as its
attitude to an arbitrarily selected reference coordinate
system. Appellant's specification ("Specification"), page 3.
The term "attitude" means the angular rotations of an eye
visual axis with respect to arbitrarily selected axes of an
eye coordinate system. Specification, page 6. Eye attitude
can mean up to three axes of rotation (pitch, roll, yaw) about
an origin of an eye coordinate system. Specification, page 4.
A head attitude monitor is added to relate the attitude of the
eye to the arbitrarily selected reference coordinate system.
Specification, page 7. The eye tracking apparatus tracks the
attitude of one or both eyes with respect to a head attached
to a body. Specification, page 4. The origin of the eye
