In your life, how many times have you been told to put down the gaming controller and do something more mentally stimulating instead? Now you have somewhat of an opportunity to do both!
Now available for the PC is OCZ OCZNIA, which is a Neural Impulse Activator. You may be wondering what that is when it's at home, so I'll tell you. The NIA will read your brain waves, which you can then assign to various functions on a keyboard. In theory, it should be feasible for you to move a character in a game just by thinking about their movements.
The makers claim that with "proper configuration", the device will allow PC users to control their games "without the use of a keyboard and minimal use of a mouse". Be warned though, gadget fans, as it'll set you back around £99.99 for the privilege.
