The World's First Commercial Brain-Computer Interface

The world's first commercial effort at a patient-ready brain computer interface is on display over at CeBIT 2010, but don't go throwing out your keyboard and mouse just yet. Intended for patients suffering from locked-in syndrome and other communication-impairing conditions, the Intendixfrom Guger Technologies allows users to input text using only their brains.

Intendix works using an EEG-sensitive cap that measures brain activity that is focused in a particular way. You simply watch a grid of letters that flashes on the screen, focusing on the letter you want to type. When the letter you want lights up, your brainwaves jump ever so slightly, allowing the EEG to determine what to type. Guger Technologies claims that the interface is simple enough that users can utilize it relatively well after just ten minutes of training.

As the brain acclimates to the system, users can type as quickly as one letter per second, making it possible to carry on a conversation and communicate complex thoughts, a step above some of the more rudimentary communication systems that have been devised over past decades.

At more than $12,000 per unit, Intendix is a bit pricey for the BCI enthusiast simply interested in the technology, but the commercialization of the product does signal a new degree of accessibility to brain computer interfacing. It doesn't appear we're going to be mind-melding with our PCs anytime soon, but this certainly marks a small step in that direction.

Scientist invents computer pillow to stop snoring

Invention by German professor shifts the head's sleeping position until the noise stops. It can also be used for neck massages. A German scientist has come up with a solution for snoring, a computerized pillow that shifts the head's sleeping position until the noise stops.

Daryoush Bazargani, a professor of computer science at the University of Rostock and the pillow's inventor, was displaying a prototype of his pillow at a health conference in Germany on Wednesday.

"The pillow is attached to a computer, which is the size of a book, rests on a bedside table, and analyzes snoring noises," Bazargani told Reuters.

"The computer then reduces or enlarges air compartments within the pillow to facilitate nasal airflow to minimize snoring as the user shifts during sleep," he said.

The ergonomic pillow can also be used for neck massages. Bazargani said several U.S. firms were interested in manufacturing the pillow.

"I invented it because I snore," he said. "I tried all sorts of products, but nothing worked. I hope people who use it will sleep more peacefully."
