Last week, we told you about Mindflex, a Mattel toy that lets players move objects with their brains. This week comes word that the same technology is making its way into a more functional application--a wheelchair that users can maneuver with thought alone.

Toyota has developed the wheelchair in collaboration with researchers in Japan. The system analyzes brain wave data using signal-processing technology and delivers neuro-feedback to the driver.

Brain wave-detecting technology, or electroencephalography (EEG), isn't new. In layman's terms, a device, usually a cap wired with sensors, detects a person's brain waves. That information is analyzed by a computer and applied to the device in question. Scientists have pursued the technology for decades, but have had difficulty achieving short response times, explains the Associated Press.

Toyota's mind-controlled wheelchair, however, has what appears to be the quickest response time yet: 125 milliseconds, or 125 thousandths of a second. The user can almost instantly steer right, left, and forward. To stop, the person in the chair must puff up a cheek, a motion that's then detected by the headpiece.

Because of this quick response time, plans are under way to turn the wheelchair into a commercial health care product. The most practical use would be for rehabilitation patients who have been paralyzed, suffered a stroke, or have other conditions that hinder their muscle control. So far, the research has centered on brain waves related to imaginary hand and foot control. However, Toyota hopes the system could ultimately be applied to brain waves generated by emotions. … Read more

First off, let me say I've always wanted to make things move with my mind--at least, some small amount of levitation, like, say, lifting a car through the air like Yoda lifted Luke Skywalker's X-Wing. "Star Wars" has played no small part in that fantasy. Oh, wait, did I say fantasy?

Mattel is releasing a toy this holiday that actually lets people raise and lower things with their mind. Well, make that one thing: a blue foam ball.

Obviously, when Mattel reps called CNET asking for a meeting, we quickly ushered them in. We'd heard about this product at CES and in other applications in the past, including the Swedish Mindball (no, we're not making that up). But Mattel's desire to bring this to the masses is admirable, and as we were soon to find out, bizarre. Look above to see the somewhat embarrassing video if you have any doubts.

Like something dropped in out of a late-'70s science fiction movie, Mindflex comes in two parts: a stark white-and-blue plastic obstacle course for a series of small foam balls, and a strange wireless headset/headband. The parts were unloaded from a shopping bag here at our CNET Labs, and quickly assembled. The obstacle course looks almost like a future version of the old kinetic board game, Mouse Trap. Except, as we said, this one's mind-controlled.

Mattel's representatives showed how Mindflex worked with a demonstration before throwing me into amateur mind control, raising and lowering the blue ball through a series of plastic hoops and tunnels.

Mindflex announces the start of challenges (with a straight-from-Epcot robotic female voice), and then players can register their successful moves by pressing buttons on the front of the machine. A large knob turns the motorized fan around the circular track, carrying the ball around the mini-course.

The brain control part comes in when raising and lowering the ball (activating and deactivating the fan), which is all triggered via what the headset is reading from my little brain. To be specific, the control is done digitally: the headband senses concentration and relaxation, and raises and lowers the ball accordingly. Then, it was my turn. … Read more
