Writing with your brain

Hi,

This may seem very weird but on the Gadget Show I saw the most AMAZING thing that I have ever seen in my entire life! It's not just what it is used for but it's how it works. It is a helmet sort of thing that you wear and is wired up but then on a screen SOMEHOW instead of clicking button it writes the text from what you are thinking! So literally you think what you want to write!

1. Do you know how it works?
2. Do you know what it's called?
3. Is it out for perchase already or not yet?
4. How much money will it be? (Preferably in £s but you can write prices in $s)

in development

it measures the electrical activity in the brain as we think

the computer can relate the measurement to repeated motions on the cursor

when perfected it will be a huge benefit to people , like stephen Hawking, who cannot control
their bodies but can think

the 1900s were the age of physics
the 2000s will be the age of biology and brain science

keep reading and learning

Is it not amazing: that my thoughts become words in my mind, related to the look of marks on paper, movement of fingers to type keys, translation to bits in a computer, organized and sent by radio waves to your computer, made into images on the screen, travel by light to your eyes. make electrical signals in the nerves in the eye, processed into images in your brain, decoded into sound and words and thoughts?

that device would just "cut out some of the middlemen"

Every time you use a muscle, there is detectable electrical activity in your brain. This means that there could be an application that would convert your finger movements on a keyboard into pulses that can be translated directly into keystrokes. More, if you THINK about the movement, there are very similar signals in the brain to actually doing the movements.

The biggest problem is that the signals vary from person to person, rather like speech recognition. So, the application needs a lot of "training" to work for any one person.
