Eye-controlled wheelchair aids handicapped
A motorized wheel chair di
rected and controlled solely by
movements of the occupant’s eyes
was accepted recently for evalu
ation and testing by the Institute
of Rehabilitation Medicine at New
York University Medical Center.
The electric motor-driven chair
is controlled by a sight switch,
using technology developed under
direction of the National Aero
nautics and Space Administration.
Dr. Howard A. Rusk, director
of the rehabilitation center, esti
mates that more than 100,000
quadriplegics (persons with no
use of their arms and legs) can
achieve mobility if this device
can be made available to them.
“I would say that 100,000 is a
conservative estimate of the num
ber of handicapped people who
could be benefitted in the United
States alone,” Rusk said.
Eighth in a series of proto
type chairs built by the Missile
and Space Support Division of
Hayes International Corp., Hunts
ville, Ala., the chair was presented
to NYU by George Scharffenber-
ger, president of City Investing
Co., the Hayes Corporation’s par
ent firm. Hayes developed the
sight switch control under con
tract to NASA.
Early in NASA’s manned space
flight program, space engineers
saw a need for a device that would
permit astronauts to operate
spacecraft controls when strong
“G” forces would prevent move
ment of their arms.
Engineers found that G forces
would not be as severe a con
straint as anticipated and astro
nauts could control their space
vehicles without resorting to the
sight switch device.
The Hayes Corporation has
continued to develop commercial
applications of the sight switch
technology under a licensing
agreement with NASA.
Five other chairs are being
tested in hospitals and rehabili
tation centers and two more are
in regular use by individual quad
riplegics in a continuing testing
program. NYU Medical Center
technicians noted that handi
capped patients have been able to
learn reasonable facility in oper
ating the chair in as little as two
or three hours use.
Members of the rehabilitation
center’s staff and representatives
of the manufacturer emphasized
that many more months of evalu
ation would be needed before the
device would be widely available
commercially.
But Bob G. Weaver, the Hayes
engineer who demonstrated the
chair, described it as “one of the
most encouraging instances to
date of the direct use of NASA-
developed technology to meet an
urgent need in the private and
public sector.”
The Hayes sight switch-con-
trolled wheel chair incorporates
a battery-powered commercially
available wheel chair with a sight
switch control device using high-
reliability solid-state components.
Presently the chair itself costs
about $700. With the sight switch
device added, total cost of the
chair is about $1,500, Hayes rep
resentatives said. A considerably
lower total price is anticipated
if the chair is produced com
mercially.
The sight switch itself is
mounted on a conventional spec
tacle frame worn by the chair
operator. The device directs low-
intensity beams to each of the
patient’s eyes. A photo-detector
mounted adjacent to the light
source senses the intensity of
light normally reflected from the
white of the eye.
When the eye is moved so that
the darker iris intersects the
beam, a sudden decrease in re
flected light is sensed by the
photodetector and a signal is
generated to initiate an action.
The left eye switch controls
the forward-reverse motion of the
chair and the right eye switch
controls steering. Start-stop and
reverse impulses are sequential,
with one impulse imparting for
ward motion, the next stopping
the chair and a third reversing it.
To go from reverse motion to
ahead, the operator signals once
to stop and then again to go for
ward.
Since the light reflecting prop
erties of the eyelid and the eyeball
are nearly the same, false actua
tion by blinking the eyelids is
eliminated. The sight switch
sensor is aimed at the upper out
side eyelid area when the eye is
looking straight foi-ward.
The operator can blink, look
ahead, look hard to the left or
right, or look directly upward
without actuating the switch. But
a definite upward and outward
diagonal glance will actuate the
switch.
College of Veterinary Medicine honors 30
Twenty-four students, five fac
ulty members and a student’s wife

ing the annual Honors Convoca
tion for the College of Veterinary
Medicine.
The program recognizes the top

The award, selected by the stu
dent members, is based on teach
ing ability, leadership, individual
integrity and efforts made in stu
dent relations.
The Texas Veterinary Medical
Association made two $100
awards to a member of the teach
ing faculty and a member of the
research faculty.
Dr. Charles F. Hall, professor
of veterinary microbiology, re
ceived the research award, and
Dr. James G. Anderson, assistant
professor of veterinary physiol
ogy and pharmacology, was
awarded the teaching honor.

6 cadets commissioned Friday,
A&M’s first midyear group
Six Texas A&M cadets were
commissioned as Air Force of
ficers Friday, becoming the first
group of new second lieutenants
sworn in at the university dur
ing mid-year.
Commissioning is normally held
in conjunction with regular fall
and spring commencement.
Receiving the gold bar were
2nd Lts. Armando A. Denhett of
McAllen; Darryl S. English, Hous
ton; Teed M. Moseley, Grand
Prairie; Robert R. Peavey, San
Antonio; James W. Walker, Wic
hita, Kan., and Gregg K. Weaver,
Midland.
The oath was administered and
bars were presented by Lt. Col.
Thomas W. Comstock, acting pro
fessor of aerospace studies.
Comstock said the mid-year
commissioning became possible by
the department offering for the
first time senior level aerospace
studies courses during the sum
mer.
Under previous scheduling, the
six students would have been
required to return for the fall
semester to get the course and
complete commissioning require
ments. .
Among requirements are satis
factory completion of the academ
ic degree program and attendance
at summer field training. All
six of the students attended camp
last summer.
Maj. Charles Haney of the
Aerospace Studies Department
said two other cadets will be com
missioned on completing the pro
gram in August.
