  Emotions play a central role in most forms of natural human interaction so we
may expect that computational methods for the processing and expression of
emotions will play a growing role in human-computer interaction. The OCC model
has established itself as the standard model for emotion synthesis. A large
number of studies employed the OCC model to generate emotions for their
embodied characters. Many developers of such characters believe that the OCC
model will be all they ever need to equip their character with emotions. This
study reflects on the limitations of the OCC model specifically, and on the
emotion models in general due to their dependency on artificial intelligence.
