V.E.R.N. is engineered to be fast. So fast that humans won't perceive it. Why is this important? Because the closer V.E.R.N. is placed to the source, or "closer to the metal," the faster the end user can utilize the emotional analysis.
How fast? We benchmarked it on a single 1gb CPU with 1bg Bandwidth and the little bugger can analyze sentences around .26ms on average.
So your operator already knows what the people are feeling because V.E.R.N. has told them as the communication is received. This unlocks a wide variety of uses--to be an assistant in real time--to real people.
