Pavlas takes part in eye movement study

A&M researcher Charles Shea places the eye tracking device on quarterback Lance Pavlas.
By RICHARD TIJERINA
Of The Battalion Staff
Call him Lance Pavlas, Jedi
Knight.
The junior quarterback from
Tombafl found himself playing
the part of athlete turned guinea
pig Wednesday when he took
part in an experiment by a Texas
A&M researcner.
Dr. Charles Shea of the De-
E artment of Health and Kineseo-
>gy has been working for six
years on an instrument that could
make everyday functions like
opening the door and turning on
a television as easy as looking at
them.
But there’s more than meets
the eye.
Shea’s research led him to be
lieve the apparatus could be used
to improve an athlete’s perfor
mance. Shea approached Coach
R.C. Slocum about the possibility
of placing a specialized helmet on
Pavlas that would monitor on vi
deotape the quarterback’s eye
movements.
The helmet, which Shea valued
at about $50,000, was rigged with
one large lens on the top that re
cords Pavlas’ field of vision. That
produced the image on Shea’s
TV screen. Two small sensors,
which are detectors that pick up
the movement of the eye, were lo
cated in front of Pavlas’ face.
They were placed where the face
mask normally would be on a reg
ular helmet.
The sensors bounce an in
frared light off Pavlas’ eyes. The
dark part of the eyes reflect dif
ferently than the light parts, and
the sensors pick up the
movement.
One sensor picks up vertical
eye movement, the other hori
zontal.
The vertical and horizontal
movements were reproduced on
the TV screen as crossing white
lines. The lines are transferred
on Pavlas’ field of vision.
The experiment was tried out
for the first time Wednesday at
Kyle Field, and for five minutes
Pavlas turned into some kind of
“super quarterback.”
Pavlas put the helmet on half
way into practice, and for the
next few minutes took snaps and
threw to receivers in scrimmage
situations. However, Shea’s mod
ified helmet and the cords that
connected Pavlas to the video ma
chine might have been too much.
He completed just one pass in
eight attempts, much to tne cha
grin of his teammates.
“Use the Force, my son,”
shouted linebacker Anthony Wil
liams, referring to Obi Wan Ke-
nobi’s line toward the ending of
Star Wars.
Shea said he and his staff will
study the videotape of the experi
ment, then hand it over to Slo
cum.
“It’s in the early stages of de
velopment, so we’re really just
looking at exploring at what it can
do,” Slocum said. “I see it primar
ily as a teaching aid for coaches.
This records what the quar
terback actually sees, not just
what he said he saw.”
Pavlas said he saw his receivers
well, despite the specialized hel
met obstructing his view some
what.
“It was a little different today,’’
Pavlas said. “It’s kind of weird
having a cord hooked up to you
— it was like a tail or something.
“It blocks your vision a little bit,
but it was OK. We’re going to
have to wait to see what the film
looks like and decide if it’s going
to be a helpful tool.”
Shea has been targeting his re
search toward helping people
make chores easier, including the
use of machines and computers,
turning lights on or off and con
trolling robots.
Shea said he will continue to do
research with the A&M football
program, and that hopefully Pav
las will be able to wear the helmet
in a real, non-contact scrimmage
toward the end of spring drills.
The only problem with the hel
met is that Pavlas moves around,
and up until now the equipment
has only been used in the labo
ratory by mobile subjects, Shea
said.
“There’s a lot of work from he
re,” he said. “We’ve already re-
congnized a number of things we
need to do before it can be used
efficiently out in the field.
“This is the biggest challenge
we’ve had.”
