For a sight of an evolving technology that promises to shake video gaming to its foundation, check out “Throw Trucks With Your Mind”.
Unlike most video games, it doesn't rely solely on a mouse. Instead, its players also put on a headset that enables them to throw trucks or other virtual objects simply by thinking.
And that's just for starters. Advocates of so-called neurogaming（交感神经游戏）say the concept in a few years will combine a wide variety of physiological factors, from a player's heart rate and hand gestures to pupil dilation(瞳孔扩张) and emotions. Moreover, they imagine many such games being developed to improve the health, brainpower and skills of those playing them.
The electroencephalography(脑电波仪), or EEG, headset used to throw trucks and other objects onto enemies was made by San Jose, California.-based NeuroSky. It measures separate brainwave frequencies that reflect how focused the player is and how calm they are, according to Lat Ware of Emeryville, California., who developed the game. The game, which can be purchased at www.throwtrucks.com, costs $25, or $99 with the headset.
Ware, 29, said it's possible to move a pear or other small virtual object if the player is calm, but not focused, or vice versa. But he said both mental states are essential to flatten an enemy with a huge truck, which takes considerable concentration.
Although only a few neurogames have been introduced so far and their action tends to be fairly limited, the games are expected to become far more challenging - and multipurpose - as the software and related technology improves.
One concept being explored is to develop games that adjust their action according to the player's changing emotions. These are measured by such factors as their facial expressions, eye movement and skin-conductance(皮肤导电) levels. Another approach is to make games that influence how the player thinks and feels.
Consider Los Angeles-based Melon, which, like "Throw Trucks With Your Mind," was recently launched via the online fundraising site Kickstarter. Melon officials say their first game-- which challenges players to fold origami（折纸） with their mind, using NeuroSky's EEG headset -- helps people "learn how to focus, relax and meditate better."
