Abstract : The Hybrid Immersive / Non-Immersive Virtual Environment workstation combines two technologies for the presentation and exploration of virtual spaces. The Immersive and Non-Immersive components of the system are complimentary in that each approach provides a distinct perspective on the virtual environment being examined. The Immersive component provides a user with a computer generated environment which completely surrounds the user. The computer generates images which surround the user in the virtual space and provides a first person perspective. Thus, if one is looking around in an environment along the coast then as one looks about, one can see the ocean and sea shore. This first person point of view will provide a good sense of the surroundings and the nearby features. The Non-Immersive component of the system provides more of an overall view of the scene, much as one might gain from an aerial photograph of an area. In contrast to the Immersive experience, the Non-Immersive experience provides an overall impression of the situation and provides a context for overall strategic decision making. We are experimenting with the components each part of the system can use and looking for effective combinations. In particular, we have been looking at using a projective image surface for the Non-Immersive user.
