Deep
in
the
heart
of
Canada’s
largest
children’s
rehabilitation
hospital,
Tom
Chau
is
giving
disabled
children
a
hand.
Tom,
who
earned
his
PhD
in
Systems
Design
at
Waterloo
in
1998,
leads
a
team
of
researchers
at
Bloorview
Kids
Rehab
in
developing
creative
devices
to
help
improve
the
lives
of
injured
or
disabled
kids,
who
often
struggle
with
so-called
adaptive
technologies.
“We
want
to
move
the
onus
from
individuals
adapting
to
technology
to
the
technology
adapting
to
individuals,”
Tom
says.
A
case
in
point:
a
“smart”
prosthetic
hand
that
gives
children
with
amputated
hands
and
forearms
better
fine-motor
control.
A
miniature
microphone
embedded
in
the
hand
captures
the
vibrations
of
the
arm’s
contracting
muscles.
Another
device
interprets
the
muscle’s
sounds,
telling
the
hand
to
open,
close,
or
grasp
as
a
normal
hand
would.
Tom
has
also
created
a
virtual
musical
instrument
for
kids
with
limited
upper
body
movement.
The
kids
see
themselves
among
large
colourful
dots
on
a
TV
screen.
Each
dot
represents
a
musical
note,
and
when
a
dot
is
“touched”
by
an
on-screen
hand,
arm,
or
head,
a
computer
plays
the
note
aloud.
Kids
can
play
from
a
score
or
create
their
own
music.
Families
who
have
benefited
from
Tom’s
creations
often
write
or
call
to
express
their
gratitude.
But
this
is
only
one
reason
he
continues.
“I
know
there
are
always
unmet
needs
that
are
waiting
to
be
addressed,”
he
says.
