text: How people feel it depends on them. most people are happy and others sad but every single people can be happy it depends on them not in other persons. The people that are always happy are the ones who thinks positive the ones that love their self a machine can read their faces but the machine doesn't know that humans can change their mind in less than an minute we can be happy and then we can be sad for a sad news but for the computer it will take time to know when human change emotions because it has to read I again the whole face , compare to us the human can see fast when other person get sad. like a quote it say "The Mona Lisa desmonstrate ir really intended to bring a smile to your face, while it shows just how much this computer can do". this mean that the computer is smart it can read faces .
