A video game that reads your mind

"What was I thinking?" just took on new meaning for video game fans. (And no, we're not talking about the reaction they may have to purchasing the latest title for $69.99.)

Neurosky, a company that specializes in wearable sensors, is set to debut "a brainwave-controlled video game" at this week's Tokyo Game Show.

PC World reports:

While playing the game, which is a technical demonstration and not a finished product, a special headset will monitor the user's state of relaxation or concentration and based on this allow them to perform certain actions in the game, NeuroSky said in a statement.

Ars Techica reminds that this isn't the first time controlling a game with just one's mind has been tried. And they point out that video game control technology has come a long way from the days of a joystick and a single button, (Atari, anyone?) citing Nintendo's innovations with the Wii and Wii Fit.
