Socially communicative characters for interactive applications

Interactive Face Animation - Comprehensive Environment (iFACE) is a general-purpose software framework
that encapsulates the functionality of “face multimedia object” for a variety of interactive applications such as
games and online services. iFACE exposes programming interfaces and provides authoring and scripting tools to
design a face object, define its behaviours, and animate it through static or interactive situations. The framework
is based on four parameterized spaces of Geometry, Mood, Personality, and Knowledge that together form the
appearance and behaviour of the face object. iFACE can function as a common “face engine” for design and runtime
environments to simplify the work of content and software developers.
