Computer games can be great fun, but the way you play them is always changing. Ricky tried out a brand new game that works using the power of your mind, instead of a controller!
Check out that head set! It's called NeuroSky and has three sensors that pick up on your brainwaves to see how relaxed you are and whether you're paying attention.
The more you concentrate, the better you'll do. These graphics show your levels of concentration and relaxation... Looks like Ricky should be trying a bit harder!
You can still use a keyboard to move your avatar in the virtual world, but when it comes to pushing or pulling things around, it's all about your mind power.
The technology is still pretty new and even though Ricky tried really hard, he said it didn't always work.
But developers are adjusting the technology all the time and it's hoped that as well as making gaming more fun, it could also help with things like medical training in the future too.
