The "Force Trainer" wasn't the only new product unveiled at CES 2009 that uses Neurosky's new EEG neurofeedback system.  Even the toy mammoth Mattel has decided to test the waters with this new technology.  

 

  

Mind Flex is a game featuring an obstacle course that you must use your mind to navigate a small sphere through.  The headset looks slightly different than the one included with the "Force Trainer" - it has one sensor that rests against your forehead and two more that clip onto your earlobes.  Apparently the sensors use only theta-wave activity to control the sphere around the course - most likely triggered only during concentration and focus.  The headset is wireless and transmits signals to the game using radio frequencies.

The sphere moves around the course using a small fan activated by your brainwaves.  The fan actually makes the ball appear to levitate as it navigates through a series of hoops around the mouse-trap like course.

Let's hope Mattel actually follows through with this thing into production.  They plan on selling it for only $80!
