text: When the software can read fear or worry on a students face with confusion or anger the software could realize that the student doesn't understand the problem, but is too shy to ask for help. The software could find extra help for the student on the internet. It could find the student some practice problems. If needed the software could even find a video explaining how to work through the problem. As a last ditch effort the software could notify the teacher that the student doesn't understand the problem.
