Deaf or hearing loss is a condition of inability to hear something, either totally or partially. Hearing loss greatly affects the life of a person in communicating with the people around him. Deaf people will be very difficult
when in a medical emergency, this is because the medical emergency situation requires fast action. The Healthy Phone application is a mobile medical emergency call application
that can help people with hearing impaired when in emergency situations.
With the Healthy Phone application, the user only needs
to
select
an
icon
that
suits
the
situation
encountered
in
touchscreen
mobile
device
then
the
message
will
be
sent
to
the
nearest
hospital.
To
search
for
icons

corresponding
to
emergencies,
the
User
Centered
Design
(UCD)
method
is

used.
This
application
is
very
helpful
for
deaf
people
because
this
application

does
not
require
audio
communication
and
user
location
is
also
sent
automatically
to
the
nearest
hospital.
The
results
were
analyzed
using
four
emergency

event
scenarios
with
a total
score
of
87%
and
an
average
user
time
of
less
than

0:42
sec indicating
that
the
study
was
successful
in
designing
a
mobile
medical

emergency
call
application
according
to
user
requirements
