I mentioned this before like, a year ago, but the collars in the movie "Up" could potentially be possible only under two circumstances.
One: Dogs would need to have a portion of the brain that allows for speech, similar to humans.
Two: There would need to be a way to connect the wares to both the brain and the voice box that can also translate into the collar. This meaning that there would either have to be an implant in the brain that somehow transmits a signal to the collar, or an implant that runs from the brain to the 'voice box' and transmits the signal and tone/volume/etc. into the collar.
Movie science is fascinating. |
