In the movie 아바타 (2009), during the last battle scene when they communicate with each other 의해 touching their throats is that 아바타 technology 또는 "powers", 또는 is it the humans technology?
It is human technology. I believe that Jack 또는 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.
