text: When it comes to school, students will not always tell the truth. They may lie about not doing their homework or be untruthful about whether they were involved in a fight. The FACS machine could solve that issue as it is able to determine whether someone is lying or not based on their expression which is stated in the quote," To an expert, faces don't lie; these muscle clues are sometimes used to spot when a "smiling" politician or celebrity isn't being truthful." This machine is able to examine the details of one's face to find out if they are lying or not. It examines the key traits of each specific emotion and if they are not meant, that is how it knows whther the truth has been told or not. Students will no longer bee able to weasel their way out of punishment due to their superior lying skills as the FACS machine is able to see through the lies. This is not the only thing this machine can do though for schools.
