Many applications, such as virtual reality theatre, or games in an educations context, require an approach that uses immersion as a way to involve the user in a more compelling way. To achieve such a high level of user involvement, we explore the use of state-of-the-art game technology for developing such applications. Related research issues encompass, the use of operating system level multimedia technology (such as DirectX), the architure and extensibility of commercial game engines (such as the Half Life 2 Source SDK), and the use of communcation facilities to allow multimodal interaction (such as the AMICO toolkit).
