Applications of the New: Using brain waves to execute commands
I noticed an article recently from Kotaku, a gaming website, that featured the "Epoc," a device that uses the user's brain waves to move objects on a screen within a video game. Developed by Emotiv, the headpiece for the device looks at 14 points on the user's brain to detect electrical energy that flows from neuron to neuron. The game "learns" how your brain works and tries replicating that pattern to specific commands. The clip in the link shows the user levitating a block with just his mind.
Now this concept is quite amazing. The device itself is in a very early development stage and still has some bugs. Within video games, the Epoc could detect your emotions at each specific time in the game. For example, if you are playing a horror adventure game, the device could detect when you are the most scared and enhance the game accordingly.
The concept is almost science fiction in nature. Controlling things with our minds is a frequent fantasy of that kind of writer. This concept could be applied to many things in the future, but we'd first have to see how it develops in terms of the video game market first.
