Gamers set aside their joysticks recently to test out a new video game. All they needed instead? The power of thought.

InteraXon, a Canadian digital innovations company, was the hit of CES when it unveiled the latest products incorporating Thought Controlled Computing -- a technology that lets users control a digital interface using simply the power of their concentration. Their creations include thought-controlled 3D glasses as well as an iPad game that tests a person’s ability to focus their mind for an extended period of time.

“We’ve developed a simple sensor that sits on your forehead and reads your brainwaves," InteraXon CEO Ariel Garten told FoxNews.com. "It’s just like a heart monitor that can read your heart rate. And the software translates your brainwave data and uses it to control your virtual world.”

She called it a brain/computer interface, or BCI, and InteraXon builds it into a simple, lightweight headband. “You have patterns of thought that are readable,” Garten explained. Enter the company's 3D TV glasses, which can detect your mood and will adjust what you’re watching according to how you’re feeling. “It gives you the ability to watch a movie or televised content, and it knows the state that you’re in, whether it be scared, excited, or bored,” Garten told FoxNews.com. “This is not just an immersive environment because it’s 3D, it’s an immersive environment because it understands you.”

“This is just the beginning of an enormous industry to understand brain activity, to use it, and to have intelligent responses to brain-activating activities,” Carlen told FoxNews.com. “Ultimately, we’ll have an intelligent response simulation that can modulate to what you are thinking. These are just the early days, but this is going to be a multi-billion dollar industry.”

“In the short term, we’re going to see these kinds of systems integrated in home devices like cell phones and televisions. But in the long term, it’s going to be the way we control the world on a regular basis.”
