Synchronization of speech, facial expressions and body gestures is one of the most critical problems in realistic avatar animation in virtual environments. In this paper, we address this problem by proposing a new high-level animation language to describe avatar animation. The Avatar Markup Language (AML), based on XML, encapsulates the Text to Speech,(More)
Lifelike animated agents present a challenging ongoing agenda for research. Such agent metaphors will only be widely applicable to on-line applications when there is a standardised way to map underlying engines with the visual presentation of the agents. This paper delineates functions and specifications of two mark-up languages for scripting the animation(More)
The creation of virtual humans capable of behaving and interacting realistically with each other requires the development of autonomous believable social agents. Standard goal-oriented approaches are not well suited to it because they don't take into account important characteristics identified by the social sciences. This paper tackles the issue of a(More)
Nonverbal communication is an important aspect of real-life face-to-face interaction and one of the most efficient ways to convey emotions, therefore users should be provided the means to replicate it in the virtual world. Because articulated embodiments are well suited to provide body communication in virtual environments, this paper first reviews some of(More)
The MPEG-4 standard specifies a set of low-level animation parameters for body animation, but does not provide any high-level functionality for the control of avatars or embodied agents. In this paper, we discuss the required features for a script format allowing designers to easily specify complex bodily behaviors, and describe a system and its associated(More)
