Making a DifferenceAssistive Technology:
Technical Solutions for the Disabled
Alan Rux

2Sept 2007
Question ?
What do you do ?Answer
I’m a Engineer !
3Sept 2007
Question ?
What does that mean ?Answer
As a Engineer
I design solutions
to problems and needs that people all over the world have.
4Sept 2007
Is this right on?
Do Engineers through design solve
problems and improve the quality
of life for people around the
world.
Discussion: agree or disagree ???
5Sept 2007
Well, if so
Let me introduce you to a few
special folks who have some
needs and problems that you as an
Engineer can design solutions for
that will make a difference .
6Sept 2007
Kevin has Cerebral Palsy with no hand or foot
control, limited voice. Would like to control
selections of music and get on the internet with
email.
7Sept 2007
Derek, intelligent young 12 year old unable to control
his movements, is non-verbal, his father said he’s
trapped inside his body
8Sept 2007
Anna, 4 year old
with spinal core
injury from auto
accident
Quadriplegic with
no movement
below the neck,
verbal, wants to
control a computer
when attending
school
9Sept 2007
Fred, 55 years old person with ALS, on a mechanical respirator
,has slight muscle control, Speaks softly, Created his own
“World Art for ALS Awareness” would like to get control back
into his life.
10Sept 2007
Ethel has Cerebral Palsy with no hand
control, limited voice (non-verbal). Would like
to control a computer and earn her GED
11Sept 2007
Just a few examples of
problems that people
have and require
engineering design to
meet their needs.

Assistive Technology
Assistive technology, sometimes
known as Adaptive Technology,
includes devices or equipment
used to maintain, increase or
improve the abilities of
individuals with disabilities
19Sept 2007
Assistive technology is NOT only computer
programs or electronic devices. Since many
people think of computers when thinking of
technology, this is a common mistake.
Assistive technology doesn’t have to be high-
tech, but it should serve the purpose of
“assistance” and can include anything from a
stick one uses to reach for something to a
walker or a wheelchair, or more complex items
such as environmental controls or adapted
vehicles.

Are YOU
UP to the
Challenge ?
21Sept 2007
The Assistive Technology Program (ATP)
Assistive Technology is the application of
engineering and science to build solutions to
help physically and mentally disabled
individuals in their daily life
22Sept 2007
• Every Electrical Engineering and Computer Engineering senior does an AT project
• A unique program – one of the few in the country
– ECE undergrad program for 15 years
– Nationally recognized –senior projects published in NSF report
• Program supports over 20 local agencies
• Funded by the Zuckerberg trust fund, NSF
• Seniors gain design experience
– Work within cost and time constraints
– Responsibility for a deliverable to a client
• Service to an underserved community of mentally and physically disabled clients
• Students become more socially aware

Some Assistive Technology Tools
• Voice recognition
• Chip accelerometers (senses motion)
• Touch screens
• Environmental Controls
• Biological sensors – like the “Mind Mouse”

Theodore Seuss Geisel: Author
• In late 1990, Ted's biographers asked if, after all that he had said in his books, there was anything left unsaid. Several days later, Ted handed them a sheet of paper on which he had written:
43
• Whenever things go a bit sour in a job I'm doing, I always tell myself, "You can do better than this.
• "The best slogan I can think of to leave with the kids of the U.S.A. would be:
• 'We can…and we've got to...do better than this.'"
Sept 2007

• With all his words and pleas for
sanity, his opposition to the arms
race, illiteracy, prejudice,
pollution and greed,
• Ted was speaking to
everyone, not just
children.Sept 2007

How
Do I
start ?
46Sept 2007
At U-Mass Lowell for present students
• College of Engineering SLICE
(service learning in college of engineering)
• Capstone Design Projects
• Volunteer (ECE Dept. Assistive Technology
Program has more requests than students in
their senior year)
47Sept 2007
• Every Electrical Engineering and Computer Engineering senior does an AT project
• A unique program – one of the few in the country
– ECE undergrad program for 21 years
– Nationally recognized –senior projects published in NSF report, RESNA
• Program supports over 30 local agencies
• Funded by the Zuckerberg trust fund & NSF
• Seniors gain design experience
– Work within cost and time constraints
– Responsibility for a deliverable to a client
• Students become more socially aware

Assistive Technology
Program
Students Appling their Engineering Skills and the newest advances in technology to design devices that improve the quality of life for people with disabilities.
49Sept 2007
Assistive Technology
Program
With complex projects students team together and assign tasks that fit their direction of studies
Software

Hardware
50Sept 2007
Assistive Technology
Program
Our student’s custom
designed devices give
hope to a person that
needs that special
electronic device that
is not on the market
51Sept 2007
Assistive Technology
Program
In the Capstone Design
Program the student must
meet and interface with
their client to be sure that
the device that they
design will meet their
needs.
52Sept 2007
Assistive Technology
Program
Students present the
new Devices and
technology at many
conferences and in
published papers
RESNA
53Sept 2007
Assistive Technology
Program
Many students
become friends with
their clients and stay
in contact with them
long after the project
is completed and
after graduation.

Design
108Sept 2007
Barrier-free design strives to make
the built environment accessible to
and useable by all persons.
It promotes integration and independence through
design that is safe, functional and dignified for
everyone.
Because barrier-free design is fundamentally good
design, it is aesthetically pleasing.
