text: Another way this technology could be used is to show the expression when adds pop up, as the article states when an add that someone doesnt like pops up the next one could be an add that is related to one that is in their interests. in that form you wont see any dumb or just adds you dont need to see. Today in this scociety we use fake emotions just to be nice or so we dont get in trouble but with this technology we can truly understand and know how we humans feel. Many people lie when it comes to crimes this could help cops with their investigation go alot smoother by seeing peoples ex[pression and they could tell if the person is lieing or trying to hide things. It could possibble help end crimes.
