The telepathic communication era – IEET

If you are not a passionate hacker, don’t rush to the electronics store though: these Brain-Computer Interface (BCI) devices have still years of development to go before reaching operational maturity: the historical Twitter message took several minutes to compose and send, so don’t plan to write a long…

Of course, the most natural user interface of all would be when the computer can read your mind with no effort on the user’s part. This is the promise of research around brain-computer interaction. Gaming is one of the first areas where we could see this type of interface come into play. In fact, a company called NeuroSky already offers some level of brainwave sensing for game play. But brain-computer interaction could do so much more than operate games. At Microsoft, for example, we’re thinking about how a computer could tailor the information it’s presenting based on a user’s state.

Imagine having the ability to turn on the television and change the channel without using a remote control. Or better yet, imagine navigating the internet and sending emails using just the power of your thoughts. Although it may sounds like something out of a science fiction movie, these ideas are becoming a reality. The brain-computer interface is the next technological achievement that blurs the line between science fiction and scientific reality.

Usually wearing a silly hat and staring at the computer doesn’t do anything besides make you lonely, but now with BCI 2000, that’s going to change. You’ve probably seen some of the really great videos of researchers playing pong, typing words, and controlling robots using just their thoughts. But did you know that they all relied upon the same software program to work? Brain Computer Interface 2000 is a software tool that facilitates reading brain signals in real time. That means EEGs and ECoGs can work better and faster. Why do you care? BCI 2000 lets you control computers with your mind.

Bin He can point to a spot on the brain that gave off a sub-microvolt signal corresponding to a thought.
The University of Minnesota researcher isolated signals in separate tests with a magnetic-resonance imager and an electroencephalogram (EEG) as part of a study on brain-computer interfaces. A prototype system based on the findings used an EEG hat to capture the signals from a subject and translate them into commands controlling a simulated helicopter flight over the University campus.

Singapore, Singapore, September 02, 2009 –(PR.com)– Two teams of engineers from A*STAR’s Institute for Infocomm Research (I2R) have won the Institution of Engineers Singapore (IES) Prestigious Engineering Achievement Award 2009 for their research and development work. The first team won it for ‘Advancing the Brain Computer Interface (BCI) technologies’ while the second team clinched the award for their research in `Unleashing Underutilized Spectrum for Sustainable Future Communications’.

Experimental devices that read brain signals have helped paralyzed people use computers and may let amputees control bionic limbs. But existing devices use tiny electrodes that poke into the brain. Now, a University of Utah study shows that brain signals controlling arm movements can be detected accurately using new microelectrodes that sit on the brain but don’t penetrate it.

“The unique thing about this technology is that it provides lots of information out of the brain without having to put the electrodes into the brain,” says Bradley Greger, an assistant professor of bioengineering and coauthor of the study. “That lets neurosurgeons put this device under the skull but over brain areas where it would be risky to place penetrating electrodes: areas that control speech, memory and other cognitive functions.”

“Brown’s BrainGate Neural Interface System—conceived in 2000 with the help of a $4.25-million U.S. Defense Department grant—includes a baby aspirin–size brain sensor containing 100 electrodes, each thinner than a human hair, that connects to the surface of the motor cortex (the part of the brain that enables voluntary movement), registers electrical signals from nearby neurons, and transmits them through gold wires to a set of computers, processors and monitors. (ScientificAmerican.com in 2006 wrote about one patient’s experience using BrainGate during its first phase of trials.)”

“A technology currently used to monitor epilepsy is being adapted into a neural interface for people who are paralyzed or have motor impairments from neurodegenerative disease. Neurolutions, a startup based in St. Louis, is developing a small, implanted device that translates signals recorded from the surface of the brain into computer commands.

The device is based on electrocorticography (ECoG), in which a grid of electrodes is surgically placed directly on the surface of the brain to monitor electrical activity. This technology is currently used for surgical planning in patients with uncontrolled epilepsy in order to find the origin of their seizures.”

“The user focuses on a point onscreen and, as the point blinks, the headset can determine at which area of the screen the user is looking. For the wheelchair interface, a laser is used to scan for obstacles and the user is given options by way of a 3-D map on the computer screen. Although the wheelchair is limited to about two processed thought-commands per minute, the route is already planned into the chair’s navigation system, so there is not much need for more intense user input.”
