A video game in which the character is controlled directly from a player's brain without the need for wires has been developed by researchers.
Mind Balance was demonstrated for the first time using a new wireless headset, at the MIT Media Lab Europe in Dublin last month.
The game could help researchers develop brain-computer interfaces for those with limited body movement.
But, said the team, it could find its way into future video games.
"It is absolutely a possibility," Ed Lalor, research associate at the labs, told BBC News Online.
"If we can make this new wireless device that we have developed, the Cerebus, more aesthetically pleasing, a little bit smaller, that would make the device actually easier to put on and use."
