Ultrasound for virtual reality? How does this work?

[Green Xenon [Radium]]

Hi:

How does ultrasound do this?

Quotes from http://en.wikipedia.org/wiki/Virtual_reality :

“On April 7, 2005, Sony went public with the information that they had
filed for and received a patent for the idea of the non-invasive beaming
of different frequencies and patterns of ultrasonic waves directly into
the brain to recreate all five senses.[2] There has been research to
show that this is possible.”

Quotes from http://www.timesonline.co.uk/tol/news/uk/article378077.ece :

“The patent has few details, describing only a device that would fire
pulses of ultrasound at the head to modify the firing patterns of
neurons in targeted parts of the brain.”

This is so interesting. Please don’t feel insulted by the cross-posts. I
only posted to relevant NGs.

No offense but please respond with reasonable answers & keep out the
jokes, off-topic nonsense, taunts, insults, and trivializations. I am
really interested in this.

I am so interested in how ultrasound can “recreate all five senses”. Yet
I am also extremely frustrated because I can’t find any additional
information on this topic.


Thanks,
