A mobile intelligent synthetic character with natural behavior generation

As cell phones have become essential tools for human communication and especially smartphones rise as suitable devices to implement ubiquitous computing, personalized intelligent services in smartphones are required. There are many researches to implement services, and an intelligent synthetic character is one of them. This paper proposes a structure of emotional intelligent synthetic character which generates natural and flexible behaviour in various situations. In order to generate the character's more natural behaviour, we used the Bayesian networks to infer the user's states and we used OCC model to create the character's emotion. After inferring these information, the behaviours are generated through the behaviour networks with using the information. Moreover, we organized a usability test to verify a usability of the proposed structure of the character.
