text: Technology that can determine someones emotions was once thought to be a thing of the future but now that future is here. Professor Thomas Huang has been able to create a computer algorithm that determines human emotions by scanning their facial expressions. Imagine the possibilities with such software!! The most benefical area in which the computer algorithm could be used in is schools. '"A classroom computer could recognize when a student is becoming confused or bored,...Then it could modify the lesson, like an effective human instructor."' (Huang, Parahgraph 6) Not only would teachers be alerted when students were becoming distracted from their teachings, but they would also be offered suggestions on how to improve the lessons. Software such as the type that Dr. Huang has created could improve test scores across the nation and ease the workload of thousands of teachers. Why not use it?
