text: Another reason I can give is that the technology is almsot pointless when we can do this ourselves, they say it themselves "For instance, you can probably tell how a friend is feeling by the simple look on their face" The technology isnt needed when we can do this with our very own two eyes, The point of the techhnology is to give an accurate hypothosis of how we are feeling when we can give that just by talking to someone. There has been times where I've been texting people and know what there emotions is like just by texting them, when we get to know someone well enough we can sense if something is bothering them. This technology on the other hand takes that part of building a relationship with someone to a lower level, you would already know their emotions even in the classroom.
