Using brain waves to control screen cursor movements, rather than moving a mouse by hand, seems like science fiction! Yet such direct control over our environment is an integral part of the development work being undertaken by participants in the Presencia project.
The IST project Presencia is not due for completion until October 2005, yet project researchers have already developed a working brain/computer interface able to provide direct control of computers. The method is primitive as yet, but has been demonstrated to work. Users experiencing the system have a cap of electroencephalogram (EEG) electrodes placed upon their head. These electrodes are then connected to a pocket PC that records the EEG data or brain waves in real-time. Sat in front of the PC screen, users imagine moving the cursor to the left and then to the right, without actually moving their hands.
The whole procedure is repeated 20 times for each different movement while the PC records the volunteer’s brain wave data throughout. With the Presencia software trained to recognise the volunteer’s brain wave patterns, activation of a control signal then allows the user to move the on-screen cursor either to the left or to the right, simply by imagining the movement!

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
