Thanks to all these advantages, brain
waves may become the standard biometric identification, but the concept needs
some work to become a basic level of data security.
Currently, researchers are working on
other areas of application of this technology. Of course, the first to come to
mind is prosthesis, controlled by thought. In addition to medical goals, where
can such technology be used? Would you trust a car that’s driven by brain
technology & car industry.
Researchers working in the field of
biometrics, are developing technology that will allow the driver to
authenticate and determine its suitability for driving, reading his brainwaves.
Device that reads brain waves can do its job without distracting the driver
from control, periodically (or continuously) checking whether the person is
driving. Along the way, this system can monitor the physical condition of the
driver, preventing the management of persons in a state of extreme fatigue or

has improved its mind management system compared to early systems that analyzed
the signal every few seconds. In addition, the system is adjusted to the individual
characteristics of the person who manages it, improving the effectiveness of
their reactions to the teams. Commands for smooth turns left and right, forward
movements are processed every 125 milliseconds by analyzing brain waves using
signal processing technology.
Probably, the driver of special
vehicles equipped with an authentication system for brain waves, it is
necessary to wear a hat with sensors. Alternatively, sensors built into the
driver’s seat headrest can be used in commercial systems samples. The device
prototype, tested by researchers, processed data on alpha and beta rhythms
obtained with the help of EEG, comparing them with the records of electrical
activity of the driver’s brain, obtained earlier.
Brain wave analysis data is displayed
on-screen in real time, establishing a neural connection with a human for
effective operation. “Figure” of the electrical activity of the brain
of different people is individual and can be used as a “password”.
Also, the nature of brain waves can recognize the state of alcoholic, narcotic
intoxication or just extreme fatigue – and do not let the driver poses a threat
to road safety, and start the engine.
tablets by thought.
If devices with touch screens are our
present, then devices controlled without hands are our future. Samsung company
announced its desire to bring to the market tablets, guided by thought, aimed
at people with disabilities who are experiencing difficulties with the use of
Samsung, along with researchers from
the University of Texas, is working on the creation of devices that interpret
brain waves using special EEG helmets. This technology is at an early stage of
development, but it is already functional: its accuracy is from 80 to 95%, and
the actions can be performed at intervals of five seconds.
Samsung and university researchers
have developed an interface that allows users to run applications on Galaxy
Note 10.1, focusing on them look. To do this, however, you need an awkward EEG
helmet. Over time, the technology will allow to select contacts and songs, turn
on and off the device and more.
According to Insoo Kim, Samsung’s
leading researcher, “several years ago, a small keypad was the only input
modality to control the phone, but nowadays the user can use voice, touch,
gesture, and eye movement to control and interact with mobile devices, adding
more input modalities will provide us with more convenient and richer ways of
interacting with mobile devices.” Researchers are working to simplify the
configuration of EEG helmets, to improve the reading of brain waves and their
more compact design. ”
“It is nearly impossible to
accurately predict what the future might bring,” says Kim, “but given the broad
support for initiatives such as the U.S. BRAIN initiative, improvements in
man-machine interfaces seem inevitable”.1
technology in music & Art.
While scientists are looking for the
best way to control various gadgets with the power of thought, artists are
already creating masterpieces in this way. Art has become one of the first
industries where brain reading technology is becoming more popular every day
and finding new uses.
Although at first glance, the use of
high technologies in art is unjustified, experts say that there is a practical
benefit. Artists help to see how the power of thought can look in reality, what
advantages and disadvantages it has. Thanks to this, in the future it will be
easier for scientists to create a neural interface for daily use. Process of
interaction between music and computer science compares with the natural
phenomenon of the “water cycle in nature”. Information technologies
have an impact on musical art, and musical art, in turn, influences the
development of information technology. The direction of musical informatics is
quite new for modern science and exists no more than ten years. Based on the
study of music theory and educational sources, we can conclude that music and
computer science are interrelated with each other.
Humans have a great auditory acuity
when it comes to comparing slightly mismatched things. A healthy human brain
can produce the appropriative brainwaves for a given situation. “Musicians and
composers have been experimenting with brainwaves for almost 50 years, and the
possibility of a brain-computer interaction for direct communication and
control was first seriously investigated in the early 1970’s. This period
reflected a significant trend towards interdisciplinary practices within the
arts influenced by experimental and avant-garde artists of the time and a
growing engagement with eastern music and philosophies by those in this field”2.
How does it work?
When we talk about controlling
something with a thought, then we usually have something in mind like reading
the electrical activity of the brain that occurs during thinking. Its tracking
technology has been around for decades and is widely used in medicine –
electroencephalography (EEG) has become a standard procedure.
EEG has been used in medicine for
more than half a century as a non-invasive method for recording the electrical
activity of the brain. Electrodes are located on the surface of the scalp to
detect brain waves. The encephalograph then amplifies the signals and records
them with a wave pattern on millimeter paper or on a computer. EEG can be
combined with a special interface, which allows a person to control external
“All brain activity can be described
in musical terms. A flat-line brain signal produces a dull, computery-sounding
singing voice. Normally, an electrode channel has a bit of a wiggle to it and
you’ll hear it modulate the pitch up and down. It modulates at a slow enough
rate that we hear it as something like a vibrato or a pitch inflection”
(Christopher David Chafe, musician, scientist, director of the Stanford
University Center for Computer Research in Music and Acoustics).3
In these days, since Mind-MIDI and
brain reading devices have been delivered it has become a more revolutionary
way of making music using brainwaves in real-time. According to Aaron Thomen,
lead engineer at “Two Bit Circus VR” and developer of MindMIDI software, “brain
waves interact like radio stations with each station working in a different
layer, where all the stations are always playing. This music can be influenced
by intention, where we can hear the immediate musical feedback”4.
Companies such as “Emotiv” and
“NeuroSky” are already releasing readers for managing a variety of gadgets.
According to the founder and head of “Emotiv” Tan Le, the new generation of
“Emotiv” products is designed to make research in the field of health and
abilities of the brain more accessible. The company wants to offer scientific
instruments that students and anyone interested in brain work can afford.
Brain-computer interfaces have become a good starting point for the company,
allowing the creation of portable, affordable scanners, which helped to collect
huge amounts of data. “Emotiv” headsets among other things allow to record and
recognize emotions, as well as play games with the control of “the power
Examples of Brain-Wave music projects.
Works of Alvin Lucier, an
American composer, directly or indirectly influenced the development of
electroacoustic music, particularly in areas of minimalism and conceptualism.
He practically does not write electronic music, but only uses the most usual
acoustic measuring instruments, simple sinusoidal and pulse generators. The
composer uses them to achieve new acoustic effects, while the very fact of the
electronic origin of these effects does not interest him at all.
In 1965, Lucier created his first
performance “Music for a solo artist.” The play originated in
collaboration with a friend of the composer, Dr. Edmond Devan, a scientist who
was engaged in the biopotential of brain activity. In this composition,
electrodes are attached to the head of the performer in order to take the
electroencephalogram (EEG) of the brain. Sonogram outlines the slightest bursts
of alpha waves in the cerebral cortex and deep brain structures, and generates
them when the performer reaches the meditative state of the brain. These alpha
waves are amplified by a special amplifier, and the resulting electrical signal
attached to the sixteen percussion instruments, which are distributed over the
entire area of the space, causes them to vibrate. The vibration is obtained due
to alpha waves, which occur with complete relaxation with closed eyes, which
correspond to low-frequency oscillations of high amplitude at about 10 Hz.
Suppose a performer can close and open his eyes when he wants, which causes a
serious change in the amplitude of the alpha wave. It was an attempt to “open
the secret door”, which gives the opportunity to hear the sound of the mind in
the process. And in this aspect the play has a great freedom of action.
American conceptual artist Lisa
Park has created a musical composition using her brainwaves. She
was able to translate her brain response to feelings in musical notes. Lisa
Park practiced for a month, thinking about people and events that would help
her experience the necessary emotions, and finally she was able to play a
musical composition with a single thought power. The headset, which allows you
to record the vibrations of the brain, is called MindWave. It was developed by
the neurologists of the Californian company NeuroSky. Usually it is used to
measure the brain activity of students, which helps to control their level of
attention during classes, and also to analyze memory.
Park transmitted the vibrations of
her brain using the NeuroSky EEG mind wave headset to her computer via
Bluetooth. After that, the waves were translated into sounds and sent to
microphones located under the trays with water. In total, there were five
microphones and each of them had its own emotion tied, among them anger,
hatred, desire, sadness and happiness. The Eunoia II system reproduced her
emotional state in the form of sounds and wave vibrations on the water surface.
Park and her audience watched the fluctuations of the water, giving a visual
representation of the speed, volume and pitch of the sound. And as the brain’s
activity and emotional state changed, so did the movement of water.
The purpose of this experiment, the
girl called the desire to awaken the human emotions with the help of modern
technology and create a work of art that will allow others to see them.
Another innovative music project was
created in 2013, when physically disabled trio – Jo Portois, Andy Walker, and
Mark Rowland released world’s first dance track using the power of their
brains. “The project was funded by vodka brand Smirnoff with proceeds from
sales of the song going to the Queen Elizabeth’s Foundation for Disabled People
(QEF). This group used an emerging technology called Brain-Computer Interfaces
(BCI) to send commands to the computers by using only their brain activity. An
Electroencephalography device was also used measure the level of electrical
activity in their brains, with the help of neuroscientist Julien Castet PH D”.5
Reading brain activity benefits not
only the art. The embodiment of such technology in mass gadgets will allow them
to be more attentive to their master. For example, they will be able to select
the music depending on the mood.
Visual Mind Art.
Also, quite interesting are the
experiments of visual art. Chinese artist Jody
Xiong in the project “The Art of Thought” equipped EEG
sensors with 16 women and men in wheelchairs, many of them having amputated
Author connect these sensors to tiny
fuses attached to the paint-filled balloons. The latter were placed in front of
empty canvases. When the participants focused, an explosion occurred, and
paintings appeared in the canvas in the style of abstract art.
Another example of Visual Mind Art
was project called “Neuro-knitting”. The authors recorded brain waves of
volunteers while listening to the music of Bach, and embodied them in a
decorative pattern on scarves.
technologies on a global scale for the next two decades, what will they be?
Today, New media has long gone beyond
television, radio or the press. Now the means of communication are not limited
to only visual or audio signs, but physical impulses of the human body can also
be used in the communication process.
In the expanding media space, print,
analogue radio and television are perceived as “old” media and new
channels of information delivery and information based on digitalization are
defined as “new media”. Another proposed definition describes new
media as “digital communication channels in which text, graphic and moving
images, sound is presented in a single” package “and that have
different forms of production, distribution, reception and storage of the final
For now, with such technology it’s
impossible to think: “hi there,
computer, please open my page in a social network”, but you can already do
various creative things with it.
With a neural interface, you also do
not have to remove the phone from your pocket every time you want to switch the
track or increase the volume. The gadget will be able to detect this desire in
the mind and fulfill orders.
The main problem in the appearance of
such neuro-technologies in mass gadgets is to compare information from the EEG
sensor with real thoughts. This is a complex task that requires large amounts
of data and processing.
