Very comprehensive review of the capabilities of this Neural Impulse Actuator device.

Review :: OCZ Neural Impulse Actuator

Reading through the review it appears that a lot of the control comes from the headband interpreting facial muscle movements.  There appears to be more bio-feedback type of signal receptors on the device but the reviewers struggled to make that portion work.

The review will be updated over the next month as they have handed the N.I.A. off to one of their testers to get fully immersed in the use of the headband.

the nia has now been passed over to our Gaming/Software reviewer - Chris Buer for a full month of testing with weekly updates. These updates will be posted as additional pages in this review, so be sure to check back on a weekly basis or register over on our forums for an automatic update on when new content is added to the review.

I'll check back later.

Here's the homepage of OCZ: OCZtechnology.com

And a brief description of what the device tracks from the site:

The biopotentials include electro-myogram, electro-encephalogram and electro-oculogram, that is, electrical signals that are generated by activity patterns in muscles, brain, and eyes, respectively.

University of Washington.

Engineers at the UW have for the first time used manufacturing techniques at microscopic scales to combine a flexible, biologically safe contact lens with an imprinted electronic circuit and lights.

Go Huskies!

This is pretty cool...but I wore contacts for a long time and they suck!  Some people can wear them without any problems, my sister for one.  Me?...pain and suffering.

"Looking through a completed lens, you would see what the display is generating superimposed on the world outside," said Babak Parviz, a UW assistant professor of electrical engineering. "This is a very small step toward that goal, but I think it's extremely promising."

Pretty snazzy nonetheless.
