The Neural
Impulse Actuator
is a novel
approach to
interacting with
a computer using
biosignals,
specifically,
electrical
potentials
recorded from
the user's
forehead. These
electrical
potentials are
registered by
the centerpiece
of the NIA, the
headband, which
features 3
sensors. The
biopotentials
include electro-myogram,
electro-encephalogram,
and electro-oculogram,
that is
electrical
signals that are
generated by
activity
patterns in
muscles, brain,
and eyes
respectively.
The mass
potentials are
amplified and
de-convoluted
into different
frequency
components to
allow assignment
of different
commands to
different
channels.
Let Your
Subconscious Reflexes

Playing computer
games with the
NIA as opposed
to standard
keyboard is
different,
meaning that the
user needs to
forget some of
the learned
habits and to
aquire a
different set of
skills in order
to interface
with the
computer. The
NIA takes just a
few steps to
configure, and
gamers can be
litterally up
and running in
their favorite
game in a matter
of minutes.
Just like there
is a
conventional
memory and
muscle memory.
The user will
also develop NIA
memory and
within a short
period of time,
the body will
remember the
reactions it
underwent to
achieve the
desired actions
on the
computer.
The underlying
principle of
operation is to
present the user
with a variety
of behavioral
choices and to
let the user
adapt to the
requirements in
each scenerio.
In the begining,
most users will
primarily use
muscle signals,
however, within
a short period
of time, these
muscle signals
will become
auxillary and
more subtle
signals will
take over. Those
signals are
primarily levels
of
excitement that
cause release of
adrenaline by
the sympathetic
nervous system
and
acetylcholine by
the
parasympathetic
components of
the autonomous
nervous system.
Among those
responses are
facial and
ocular reflexes
like the eye-lid
reflex (one of
the fastest
reflexes in the
body that can be
used for
shooting), and
the pupil
reflex. Reflexes
are also
mirrored in the
governance of
facial blood
flow, i.e. the
contraction or
relaxation of
the smooth
muscles of the
blood vessels
that contribute
to the
electrical
signals. All of
these signals
are being picked
up and with
increasing
experience,
voluntary
responses will
become more and
more subordinate
and will be
replaced by
subconscious or
unconscious,
reflex-based
actions.
Interfacing
with the NIA
The nia features
an intuitive GUI
to allow the
user to
calibrate
signals and
coordinate and
assign commands.
In general, two
types of
commands are
possible, namely
so-called
switch-events¯
and joysticks¯.
Switch events
are all or
nothing
responses that
are triggered
once the signal
amplitude
exceeds a
certain
threshold and
are comparable
to a digital
mode of
operation.
Joysticks are
graded responses
on a predefined
scale, where
zones¯ of
signal strength
can be defined.
In addition to
vertical
joysticks that
reflect levels
of activity, a
horizontal
joystick based
on lateral eye
movements can be
used. Both
switch events
and joystick
zones can be
arbitrarily
bound to
keyboard keys or
mouse buttons as
they are defined
in any games
options¯.
The intuition of
the computer
behavior is the
most important
thing to
consider when
creating a
profile for a
specific game.
However, it is
in the interest
of any nia user
to try anything
that comes to
mind and to
promulgate any
profiles that
work. It is also
necessary to be
aware that the
capabilities of
the nia are
different from
those of a
keyboard, and
consequently,
the strategies
in game play
will have to be
adjusted in
order to take
advantage of the
shorter reaction
times and the
higher level of
immersion inside
the game. For
example, the nia
will work best
in very crowded
combat scenes in
FPS games where
its necessary
to shoot the
enemy with the
blink of an eye,
whereas mileage
in slow game
sequences will
vary. Also, the
nia can be used
as a
complementary
interface with
the computer in
combination with
any other input
device. For
example in games
like World of
Warcraft, the 4
or 5 most common
keys can be
bound to the nia,
and the other
keys are then
entered via
keyboard.
