Abstract. This paper presents putational mind model for lifelike animated
agents. It consists of a motivational system and an emotional system. The
motivational system guides an agent’s behaviour by generating goals. The
emotional system exerts further control over the agent’s behaviour by
regulating and modulating the way that behaviour is undertaken. The mind
model is embedded in a layered hierarchical agent architecture that provides a
framework and flexible way of modelling these system’s influence on each
other, and ultimately on the behaviour of lifelike agents. The mind model
together with the agent architecture is implemented using a logical formalism,
. the Event Calculus. We have followed this approach to develop and control
an animated lifelike agent operating in a virtual campus.
1 Introduction
Recently there is an increasingly growing interest in building animated lifelike agents
(also known as synthetic characters or creatures) in both academia and industry.
Research work has been done in various labs around the world. While the earlier
empirical studies have been very encouraging, they also suggest that simply
embodying and animating an agent is insufficient. e across as being lifelike,
an agent needs to incorporate a deeper model of motivations and emotions, and in
particular, to connect this model to agent’s behaviour-generating process.
Motivations and emotions are essential parts of our lives. They determine what we
are going to do and how to do it. They also influence how municate or interact
with others. Several researchers have acknowledged their importance in human
thinking and behaviour [1], [2], [3], and recent neurolog
