This document discusses integrating artificial intelligence and virtual reality through creating an intelligent virtual environment (IVE) suite. The IVE suite would allow a user to interact with a virtual world using natural language input. It would parse the user's text and display the desired simulation in 3D virtual space. The document outlines the proposed architecture of the IVE suite, which would include components for natural language processing, rule generation, virtual world rendering, and more. The goal is to use advances in AI and VR to enable intuitive, natural interaction between users and virtual simulations.
