The New York Times recently reported on Egyptian programmers' attempts to train computers to recognize facial expressions and define human emotion. This emerging technology field called "affective programming" could be used in a variety of applications, such as providing better learning experiences for online education programs, or even alerting drivers as they deal with stress. The technology, however, raises privacy concerns, as well as questions of accuracy (since human beings themselves commonly make mistakes when interpreting emotions).
