Imagine a computer that knows when you're happy or sad, even when you are trying to hide your emotions. New software has been developed that can tell the emotions of others. This new software, the Facial Action Coding System, is now awiting to be used by variety of industries.

However, using these complex algorithms used to decode emotions into classrooms would be extrodnary. Imagine a classroom computer that could recoginize when a student is becoming bored or confused. Dr. Huang predicts. "Then it could modify the lesson, like an effective human instructor."

You can't

probably tell how a friend is feeling simply by the look on her face. In the article it said "Using video imagery, the new emotio-recognition software tracks these facial movements."

The use of this technology to read the emotional expressions of students in a classroom is valuable. This will futher modify the way a lesson is being teached, and will increase the students ability to learn.
