We present a virtual environment application that allows users to access embedded information within an immersive virtual space. Due to the richness and complexity of this environment, efficient and easy-to-use interaction techniques are a crucial requirement. The “Virtual Venue” seamlessly combines both twoand three-dimensional interaction techniques into a single system and utilizes previously reported as well as novel techniques that fit the task of information access. We present tools for user control of the system, travel through the environment, and information retrieval, as well as authoring tools for the creation of information-rich virtual environments. A usability study and its results are also presented and discussed. The study indicates that the use of abstract information that is tightly coupled to the virtual environment can be quite successful in enhancing the relevance of both the environment and the information. Results also show that the set of well-constrained interaction techniques presented here are usable and efficient for information retrieval.
