In this paper, we describe the integration of Natural Language Processing (NLP) within an emotional planner to support Interactive Storytelling. Our emotional planner is based on a standard HSP planner, whose originality is drawn from altering the agents’ beliefs and emotional states. Each character is driven by its own planner, while characters are able to(More)
In this paper, we describe a small-scale, yet complete, integration of a real-time immersive interactive storytelling system. While significant progress has been achieved in recent years on the individual component technologies of interactive storytelling, the main objective of this work is to investigate the concept of interactive storytelling in a fully(More)
The development of complex interactive 3D systems raises the need for representations supporting more abstract descriptions of world objects, their behaviour and the world dynamics. The inclusion of Artificial Intelligence representations and their use within 3D graphic worlds face both fundamental and technical issues due to the difference in(More)
We describe recent developments in the CaveUT software, which supports immersive virtual reality installations based on the Unreal Tournament game engine. CaveUT implements several high-end VR features such as real-time stereoscopy with head and hand tracking. We demonstrate the use of CaveUT in the SAS Cube™, a PC-based CAVE™-like immersive(More)
Computer games are ideally placed to form the content of future Immersive Media, but this prospect is faced with both technical and usability issues. This paper describes an experiment in immersive gaming using a state-of-the-art computer First Person Shooter (FPS) game, in which we analyze user experience and performance through a combination of in-game(More)
Previous attempts at developing immersive versions of game engines have faced difficulties in achieving both overall high performance and preserving reusability of software developments. In this paper, we present a high-level VR middleware based on one of the most successful commercial game engines: the Unreal® Engine 3.0 (UE3). We describe a VR(More)
The development of Virtual Reality Art installations is faced with considerable difficulties, especially when one wishes to explore complex notions related to user interaction. We describe the development of a VR platform, which supports the development of such installations, from an Art+Science perspective. The system is based on a CAVETM-like immersive(More)
