RSVP Keyboard: An EEG Based Typing Interface.
[locked-in syndrome]
Humans
need
communication
.
The
desire
to
communicate
remains
one
of
the
primary
issues
for
people
with
locked-
in
syndrome
(
LIS
)
.
While
many
assistive
and
augmentative
communication
systems
that
use
various
physiological
signals
are
available
commercially
,
the
need
is
not
satisfactorily
met
.
Brain
interfaces
,
in
particular
,
those
that
utilize
event
related
potentials
(
ERP
)
in
electroencephalography
(
EEG
)
to
detect
the
intent
of
a
person
noninvasively
,
are
emerging
as
a
promising
communication
interface
to
meet
this
need
where
existing
options
are
insufficient
.
Existing
brain
interfaces
for
typing
use
many
repetitions
of
the
visual
stimuli
in
order
to
increase
accuracy
at
the
cost
of
speed
.
However
,
speed
is
also
crucial
and
is
an
integral
portion
of
peer
-
to
-
peer
communication
;
a
message
that
is
not
delivered
timely
often
looses
its
importance
.
Consequently
,
we
utilize
rapid
serial
visual
presentation
(
RSVP
)
in
conjunction
with
language
models
in
order
to
assist
letter
selection
during
the
brain
-typing
process
with
the
final
goal
of
developing
a
system
that
achieves
high
accuracy
and
speed
simultaneously
.
This
paper
presents
initial
results
from
the
RSVP
Keyboard
system
that
is
under
development
.
These
initial
results
on
healthy
and
locked-
in
subjects
show
that
single
-trial
or
few-trial
accurate
letter
selection
may
be
possible
with
the
RSVP
Keyboard
paradigm
.
