Affective computing

[attachment=16274]
INTRODUCTION
Affective computing aims at developing computers with
understanding capabilities vastly beyond today’s computer systems.
Affective computing is computing that relates to, or arises from, or
deliberately influences emotion. Affective computing also involves
giving machines skills of emotional intelligence: the ability to recognize
and respond intelligently to emotion, the ability to appropriately express
(or not express) emotion, and the ability to manage emotions.


A GENERAL OVERVIEW
A general system with users who have affect or emotion and the
surrounding world can be represented by the following sketch. Each of
the aspects shown in the figure is explained in brief afterwards.


James-Lange Theory
According to this theory, actions precede emotions and the
brain interprets said actions as emotions. A situation occurs and the brain
interprets the situation, causing a characteristic physiological response.
This may include any or all of the following: perspiration, heart rate
elevation, facial and gestural expression.
