In the movie Avatar (2009), during the last battle scene when they communicate with each other da touching their throats is that Avatar technology o "powers", o 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 o 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
