Gamers will soon be able to interact with the virtual world using their thoughts and emotions alone.
A neuro-headset which interprets the interaction of neurons in the brain will go on sale later this year.
The Epoc technology can be used to give authentic facial expressions to avatars of gamers in virtual worlds. For example, if the player smiles, winks, grimaces the headset can detect the expression and translate it to the avatar in game.
It can also read emotions of players and translate those to the virtual world. "The headset could be used to improve the realism of emotional responses of AI characters in games," said Ms Le.
"If you laughed or felt happy after killing a character in a game then your virtual buddy could admonish you for being callous," she explained.
They include excitement, meditation, tension and frustration; facial expressions such as smile, laugh, wink, shock (eyebrows raised), anger (eyebrows furrowed); and cognitive actions such as push, pull, lift, drop and rotate (on six different axis).
Gamers are able to move objects in the world just by thinking of the action.
