A vibrotactile p300-based brain-computer interface for consciousness detection and communication.
[locked-in syndrome]
Brain
-computer
interface
(
BCI
)
has
been
used
for
many
years
for
communication
in
severely
disabled
patients
.
BCI
based
on
electrophysiological
signals
has
enabled
communication
,
using
auditory
or
visual
stimuli
to
elicit
event-related
potentials
(
ERPs
)
.
The
aim
of
this
study
was
to
determine
whether
patients
with
locked-
in
syndrome
(
LIS
)
could
elicit
a
P
300
wave
,
using
a
vibrotactile
oddball
paradigm
for
establishing
somatosensory
BCI-based
communication
.
Six
chronic
LIS
patients
performed
2
electroencephalography
(
EEG
)
-
based
vibrotactile
P
300
oddball
tasks
.
After
a
simple
mental
counting
task
of
the
target
stimuli
,
participants
were
instructed
to
answer
5
questions
by
counting
the
vibration
on
either
the
right
wrist
for
"
yes
"
or
the
left
wrist
for
"
no
.
"
All
participants
were
able
to
elicit
a
P
300
wave
using
the
vibrotactile
oddball
paradigm
BCI
task
.
In
the
counting
task
,
4
patients
got
accuracies
of
100
%
(
average
above
chance
)
.
In
the
communication
task
,
one
patient
achieved
100
%
accuracy
(
average
above
chance
)
.
We
have
shown
the
feasibility
of
eliciting
a
P
300
response
using
vibrotactile
stimulation
in
patients
with
LIS
.
The
present
study
provides
evidence
that
this
approach
can
be
used
for
EEG-based
BCI
communications
in
this
patient
group
.
This
is
the
first
study
to
prove
the
feasibility
of
a
BCI
based
on
somatosensory
(
vibratory
)
stimulation
in
a
group
of
brain
-injured
patients
.
Furthermore
,
this
approach
could
be
used
for
the
detection
of
consciousness
in
non-communicating
patients
due
to
severe
brain
injuries
.
