Defining phenomena for an emotion state model in the human interface

The use of facial nonverbal behavior as an input has created a need for a robust emotion state model. Such a model would be used by the machine to determine actions appropriate to the exhibited behavior and machine state. Existing cognitive models of emotion provide a ready starting point for the development of a model for the human interface. However, these models do not account for the unique phenomenological aspects of the interface. These aspects are examined in detail from both a historical and modern perspective. The effects of the level of immersion into the virtual environment are also explored. Finally, solutions to this phenomena problem and further research paths are explored
