In one of my most favourite movies as a child "Sheena", the young girl sheena summons a hedgehog using the power of her mind / rather brain ! And now, everybody can do it thanks to the rapid advances in brain controlled interfaces that allow us to make use of machinery just by the power of our thought...wow !

The most recent breakthrough has been Asimov's brain controlled interface used in the form of a helmet. The operator wears the helmet which then picks up differences in electrical signals from the flow of blood in the brain tissues and transforms it to bits and bytes, that can be understood by the robot ! Honda company, the developers of this technology claim 90% accuracy which is a "first" in such systems. The following is a video demo of the same :

Such systems have also been in development by other companies, the principal being Emotiv who have introduced their EPOC headsets which can be used to play video games, move wheelchairs and a whole lot of unforseen applications using brain power. Soon, we would be able to unlock our car doors, switch on the computer and a whole lot more just by the power of thought. And now I see wisdom in the words of the ancient Yogic masters who always taught us to be careful and focussed about our thoughts...whoever knew that these thoughts produced differences in the flow of blood which would be picked up by machines ! So, once again... WOW !
