Five Incredible - and Real - Mind-Control Applications

even though Stocco was sitting all the way across the University of Washington's campus.
Using one human brain to direct another person's body via the Internet was an amazing
breakthrough. But other feats of mind control are already realities, particularly in the realm
of human machine interfaces (HMIs).
Here are some amazing examples of what our brains can already do.
1. Compose and Play Music
Yes, music composition always took place in the brain. But now musicians might be able to
eliminate the need for tools and interfaces like sheet music - or even playing an instrument -
by simply creating music directly with their thoughts.
Electroencephalography (EEG) headwear devices record the electric signals that are produced
when the brain is at work and can connect them wirelessly to a computer. Their wearers can also
train their minds to associate a set of EEG brain signals with a specific task.
For example, thinking about pushing a button on the computer screen produces a brainwave
pattern that computer software can then recognize and associate with that task.
To make music, such thoughts are associated with notes or sounds to create a language of
musical thought that's produced directly from the brain. With this established, users can simply
think musical scores to life and play them via the computer.

2. Screen Mobile Phone Calls
busy mobile phone users by simply monitoring the state of the user's brain.
Earlier this year, Scorcioni won an AT&T Mobile App Hackathon with the iOS app, which uses
calls to voicemail when it perceives that the user's brain is busy with other tasks. If the user's
brain is in a receptive state, it lets the call through.
With US$30,000 in Hackathon prize money in hand, Scorcioni is fine-tuning his prototype,
which he views as a first step in the way our brain states might directly control mobile devices and
our individual environments. Someday it might enable more brain-driven mobile device features that
require no user input, like his Good Tunes concept, which would read brainwaves and then play
music best matching the wearer's personal preferences for their current brain state.
3. Create a 3-D Object
Can wishing for something make it so? Well, not quite. But a Chilean company has announced the
first object to be created by thought alone - paired with the growing power of the latest 3-D
printing machines.
created the first-ever such object in January 2012.
Then the company's own software, called Emotional Evolutionary Design, displays "building
block" shapes on a computer screen.
From a basic beginning, the shapes change and "evolve," while the user's emotional positive
and negative reactions to each change are monitored by the headset. As the software processes
brain feedback, the well-received shapes and changes are kept and expanded, while the disliked
ones fade away. The process is repeated until a final object is produced according to the
thought preferences of the designer.
software to create the monster of their dreams, or nightmares, in a matter of minutes.
4. Drive a Wheelchair - And a Car
For the disabled, the ability to move about using the power of their minds could be life changing.
To that end, scientists have worked for years on wheelchairs and other devices that could restore
mobility to those who had lost control of their own bodies but still had sharp minds.
By 2009, Japanese scientists at Toyota and research lab RIKEN announced a thought-
controlled wheelchair that used an EEG sensor cap to capture brainwaves and turn them
into directional commands in just 125 thousandths of a second - with 95 percent accuracy.
At Lausanne, Switzerland's Federal Institute of Technology, scientists have added "shared
control" to the concept. Their chair's software analyzes the surrounding area's cluttered
environment and
blends that information with the driver's brain commands to avoid problems like collisions with
objects.
The system also eases the strain of command because users needn't continually instruct the
chair - the software processes a single directional command and automatically repeats it as
often as needed to navigate the space.
German engineers at the Free University of Berlin have attempted to take this concept on
the open road with a car that can be partially controlled by the driver's thoughts. The team
outfitted it with a computer system and software designed to work with Emotiv's commercially
available EEG brain-scanning headset.
Drivers were trained to produce recognizable thought commands, like "turn left," by
manipulating a virtual cube on a screen. The on-board computer then analyzed and converted
those thoughts to commands recognized by the car itself each time they were thought by the
on the long run, human machine interfaces like this could bear huge potential in combination
with autonomous driving - for example, when it comes to decide which way you want to take
on a crossroad, while the autonomous cab drives you home."
5. "Bionic" Limbs

In some instances, human machine interfaces are becoming part of the human body. One
new prosthetic even provides a sense of "touch" like that of a natural arm, because it interfaces
with the wearer's neural system by splicing to residual nerves in the partial limb.
The prosthetic sends sensory signals to the wearer's brain that produce a lifelike "feel," allowing
users to operate it by touch rather than by sight alone. This ability enables tasks many take
for granted, like removing something from inside a grocery bag, and knowing how hard to grip items
with the prosthetic hand.
Researchers at Case Western Reserve University, now working with the Defense Advanced
and was unveiled in May 2013. DARPA is a leader in the development of advanced prosthetics, in
part because more than 2,000 U.S. Service members have undergone amputations since 2000.
Another DARPA-backed prosthetic arm flips this script by efficiently transmitting information from
brain to arm, rather than vice versa, through a technique called targeted muscle re-innervation.
The procedure rewires nerves from amputated limbs to enable more natural brain control of the
prosthetic - and make possible some amazing abilities.

Glen Lehman [pictured above], who was wounded in Iraq, demonstrates his ability to
manipulate the arm with his mind, drink coffee, and bounce a tennis ball with a prosthetic limb.
In some cases, experts say, prosthetics can already offer more functionality than heavily
damaged human limbs.
