Headset that Reads Brainwaves

I haven’t posted anything in a long time, as I have been busy with other things. But I came upon new piece of technology that is just too cool to ignore.

Emotive Systems has created a headset that uses the user’s brainwaves as the interface of the computer. Thus the user can do whatever he or she wants by simply thinking about it.

This is not a completely new technology in its hardware and it is actually not very profound in scientific terms. By that I mean the device does not really know the functioning or the anatomy of the brain. It is simply an algorithm that records brainwaves when the user thinks of doing a certain task and then the computer performs that task whenever it is provided with the same input. This means that the technology is limited since the computer has to first match each of the specific tasks that it offers with a certain brainwave. However, I must add that the algorithm is not as simple as it sounds since it has to detect, filter, and recognize brainwaves. Obviously, brainwaves are much more complicated, variable and noisy than a simple digital circuit.

Nevertheless, this technology is profound in human-computer interfacing and indeed very enjoyable to use.

I think we have just seen the future of human-computer interfacing. Click on the video and watch for yourself:

This summer I am reading the Feynman Lectures on Physics written by Richard Feynman and The Selfish Gene written by Richard Dawkins. I will probably write a review on them some time before university starts.
