Previous issue date: 2017-03-09 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Modelos de simula??o de multid?es t?m tido um papel importante em ci?ncias da computa??o j? h? algumas d?cadas desde os trabalhos pioneiros. No in?cio, agentes simulados em multid?es comportavam-se todos da mesma maneira, e tal comportamento era controlado pelas mesmas regras em todos os agentes. Com o tempo, os modelos de simula??o evoluiram, e come?aram a agregar
uma maior variedade de comportamentos nos agentes. Modelos de simula??o de multid?es que implementam diferentes comportamentos nos agentes s?o chamados modelos de Multid?es Heterog?neas, em oposi??o aos modelos de Multid?es Homog?neas precedentes. Modelos de simula??o de multid?es que buscam criar agentes com comportamentos humanos realistas exploram heterogeneidade nos comportamentos dos agentes, na tentativa de atingir tal realismo. Em geral, estudos em psicologia e comportamento humano s?o usados como conhecimento de base, e os comportamentos
observados nestes estudos s?o simulados em agentes virtuais. Nesta dire??o, trabalhos recentes em simula??o de multid?es exploram caracter?sticas de personalidade e modelos de emo??es. No campo de emo??es em agentes virtuais, pesquisadores est?o tentando recriar fen?menos de cont?gio de emo??es em pequenos grupos de agentes, ou mesmo estudar o impacto de cont?gio de emo??o
entre agentes virtuais e participantes humanos. Sob a cren?a de que cont?gio de emo??o em agentes virtuais possa levar a comportamentos mais realistas em multi?es, este trabalho foca em recriar modelos computacionais de cont?gio de emo??es destinados a pequenos grupos de agentes, adaptando estes modelos para um contexto de simula??o de multid?es. / Crowd simulation models have been playing an important role in computer sciences for a few
decades now, since pioneer works. At the beginning, agents simulated on crowds behaved all the
same way, such behaviour being controlled by the same set of rules. In time, simulation models
evolved and began to incorporate greater variety of behaviours. Crowd simulation models that
implement different agent behaviours are so-called Heterogeneous Crowd models, opposing to former
Homogeneous Crowd models. Advances in crowd simulation models that attempt to make agents
with more realistic human-like behaviours explore heterogeneity of agent behaviours in order to
achieve overall simulation realism. In general, human behavioural and psychological studies are
used as base of knowledge to simulate observed human behaviours within virtual agents. Toward
this direction, later crowd simulation works explore personality traits and emotion models. Some
other work in the field of emotional virtual agents, researchers are attempting to recreate emotion
contagion phenomena in small groups of agents, and even studying emotion contagion impact
between virtual agents and human participants. Under the belief that emotion contagion in virtual
agents might lead to more realistic behaviours on crowds, this work is focused on recreating emotion
contagion computational models designed for small groups of agents, and adapting it for crowd
simulation context.
