In the movie Avatar (2009), during the last battle scene when they communicate with each other Von touching their throats is that Avatar technology oder "powers", oder is it the humans technology?

Ya human technology, throat microphones. The military uses them currantly

It was the human technology.

That movie was way better than I thought it was going to be!

It is human technology. I believe that Jack oder anyone that was with him introduced that technology to the Na'vi (it's like an off-scene thing). It is like a walkie-talkie but worn around the neck.

Probably the Human Technology

ya it is human technology its throat walkie talkie things
