text: Can we actually "calculate" emotions like math or something? How can computers recognize facial movements humans use to express how we feel? Each human has their own smile and their own unique way of showing their emotions. How can a computer that doesn't have its own intelligence or will discern how a human actually feels? Humans can simply look at someone and tell how they are feeling on the surface but humans also hide things deep within their mind. Most people who trully hold someone dere and care about them can tell when a person is hiding something through more than just facial expressions and facial movements. They can tell how a person feels by the way they are speaking and the way they move their body or thourgh physical changes throughout their body.
