EmET: Emotion Elicitation and Emotion Transition model
Abstract. Emotion is an important part of human cognition. In one or other way, emotion influences various cognition processes. For the past few decades, re-searchers are working for the integration of emotions and cognition. In this paper, we are proposing a model for emotion elicitation and emotion transition. The model is based upon well known appraisal theory of emotions and targets five primary emotions. Since emotions are continuous in nature, they keep on changing either due to another event that occurred in sequence (known as emo-tion transition) or due to time lapse (called emotion decay). Simultaneous emotion elicitation is also supported by the model. The design of model is

Nevertheless, current emotion models in software agents are much simpler as compared to human emotional complexity. Although a lot of good works have been carried out in emotion recognition and emotion expression but still lots of research is going on in the field of emotional decision making.
When we talk about the structures and eliciting conditions of emotions, there are several models to refer to. One of the most popular emotion models is from Ortony, Clore & Collins (OCC). The model describes (Ortony et. al., 1998) a hierarchy that classifies 22 emotion types. It provides a clear and convincing structure of the eliciting conditions of emotions and the variables that affect their intensities. Because these notions (i.e. events, actions, and objects) are also commonly used in agent models, this makes the OCC model suitable for use in artificial

First, the external environment is percept for some event. If some event occurs, then the event is appraised by an agent while considering its own belief, goal, resources and capa-bilities. Secondly, emotions are elicited based upon the appraised event. Thirdly, if there is no change in environment, the emotion decays gradually with time or if some event happens it changes from one state to other called as emotion transition. Naturally an agent is influenced by many factors other than visible surrounding environment, for example, the personality traits, past memories or experiences etc. Our proposed model is event based considering the visible happened event. In this paper, we have proposed a domain independent emotion elicitation and emotion transition model called EmET. The model is based upon well known appraisal theories of emotions. Moreover, if no external event occurs, the intensity of emotion decays with time. EmET also allows simultaneous occurrence of multiple emotions.
Paper is organized as follows: in section 2, we discussed the proposed model in detail. Section 3 shows the simulation of the model in the virtual environment inspired by real scenario. Section 4 compares the proposed model with the existing model. Section 5 concludes the paper with a belief discussion on future
