From their house, their school or work. Phone, laptop, computer, cars, etc. Each day a lot of inventors work hard to produce their invention to make the world better. Recently, iphone company just release a new iphone called iphone X that you can unlock the phone without using your finger, you can just look at the camera and the phone will recognize your face and open it for you. That is a really popular invention that everyone excited to buy and love to use. People create many new technology for it to communicate with humans like iphone X as an example. Thomas Huang professor of University of Illinois collaboration with Nicu Sebe professor of University of Amsterdam created a software called :"Facial Action Coding System." The software were created because Dr. Huang said that he want to develop better ways for huamsn and computers to communicate. The software can recognize humans emotions. Either, you happy, sad, fear or surprise, the computer just look at you and tell what is your feeling right the way. Because Dr. Huang is a professor at University of Illinois, beside the software he just look like every professior that have to go to class and teach. As many people know, not every time you attend the class you understand what the teacher teach you. Sometime you get bored, sometime you get confused or tired. But all of that emotions you are the only one that know about it. With that in mind, Dr. Huang wanted to bring the software to his class so he will know his lesson is actually go through students mind or not. He will know the time to change the topic to make student more productive, more happy and enjoy in his lesson. Not just only him, every teacher in the world need this sofware, everyone want their students to happy to learn. More happy you are, more focus you are in the class. The Facial Action Coding System is a valuable software for school that help teacher recognize students feeling and that can make the class better.
