NewScientist have a nice feature on a brain-controlled world that offers even paraplegic gamers the chance to explore:

Electrodes are attached to a person's scalp and electroencephalogram (EEG) equipment is used to monitor electrical activity within their brain.

In this way, the system can be trained to identify the distinctive patterns of neuronal activity produced when they imagine walking forwards, or think about moving either their left or right arm. These thoughts can then be used to navigate or make an on-screen character, or avatar, move forwards or turn left or right.

In addition, there is no need for the operator to wear a head-mounted display ? they sit inside a room (located at UCL) inside which stereo video footage is projected onto three walls and the floor. A pair of shuttered glasses creates the illusion of 3D to intensify the overall feeling of being inside the simulated reality.
