Abstract
Abstract An improved oculometry system in which the observer is enabled to move within a larger eye space than heretofore, by the use of an ultrasonic measuring system for determining the position of the observer''s eye, in a coordinate system in which the position of the oculometer is also known, the coordinates being used to compute the displacement of the observer''s eye axially from the oculometer and transversely from its axis, and the focus and axial direction of the oculometer being adjusted accordingly.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
Apparatus for continuously giving an output representative of the direction of regard of an observer who is free to move and turn within an observation volume, including: means carried in part by the observer for giving a first output representative of the coordinates of the observer''s eye in a predetermined coordinate system; optical means, including adjusting means for the focus thereof and for the angular direction of the optical axis thereof about a known center, for giving a second output in accordance with deviation of the observer''s direction of regard from the direction of said optical axis; and means energized with said first output, and settable in accordance with the coordinates in said system of said known center, for adjusting one of said adjusting means in accordance with said first output.
Claim 2
Dependent Claim
131 words
Apparatus for continuously giving an output representative of the direction of regard of an observer who is free to move and turn within an observation volume, including: means carried in part by the observer for giving a first output representative of the coordinates of the observer''s eye in a predetermined coordinate system; optical means, including adjusting means for the focus thereof and for the angular direction of the optical axis thereof about a known center, for giving a second output in accordance with deviation of the observer''s direction of regard from the direction of said optical axis; and means energized with said first output, and settable in accordance with the coordinates in said system of said known center, for adjusting one of said adjusting means in accordance with said first output.
Claim 3
Dependent Claim
139 words
Apparatus according to claim 1 in which the first named means comprises: ultrasonic apparatus, including transmitting means and receiving means, for giving a first signal representative of the location of one of said transmitting and receiving means with respect to the other; means mounting one of said transmitting and receiving means near an observer''s eye for movement unitary therewith as the observer moves and turns within said observation volume; means settable in accoRdance with the coordinates of the other of said transmitting and receiving means for deriving from said first signal a second signal representative of the coordinates of said one means; and means settable in accordance with the location of said one means relative to the observer''s eye for deriving from said second signal, as said first output, a third signal representative of the coordinates of the eye.
Claim 4
Dependent Claim
52 words
Apparatus according to claim 1 in which the last named means energized with said first output comprises means energized with said first output, and settable in accordance with the coordinates of said known center, for adjusting said optical means angularly about said center so that said axis passes through the observer''s eye.
Claim 5
Dependent Claim
84 words
Apparatus according to claim 1 in which the last named means energized with said first output comprises means energized with said first output, and settable in accordance with the coordinates of said known center, for adjusting said optical means angularly about said center so that said axis passes through the observer''s eye, and for giving a further output representative of said angular adjustment; together with means combining said second output and said further output to give an indication of the observer''s direction of regard.
Claim 6
Dependent Claim
53 words
Apparatus according to claim 1 in which the last named means energized with said first output comprises means energized with said first output, and settable in accordance with the coordinates of said known center, for adjusting the focus of said optical means to the distance from said optical means to the observer''s eye.
Claim 7
Dependent Claim
54 words
Apparatus according to claim 4 in which the last named means energized with said first output further comprises means energized with said first output, and settable in accordance with the coordinates of said known center, for adjusting the focus of said optical means to the distance from said optical means to the observer''s eye.
