A HMD is a device that is worn on the head, similar to glasses or ski goggles, visually isolating the user from the physical real-world surroundings. Head-mounted displays (HMDs) appear to be particularly accessible as they are now more affordable than ever before (Lanman et al.

There is considerable potential in expanding this work to visualize other urban environments. This model is not only a visually accurate representation of the neighborhood (buildings, streets, topography and greenery), but is also an accurate functional simulation of rainfall events. In its first innovative application of the CAVE ® technology to the urban environment, Rowan’s College of Engineering recently created a 3‐D immersive model of a 50‐block section of the Cramer Hill neighborhood in the City of Camden, which suffers from a severe, chronic flooding problem, in order to identify effective, cost efficient solutions. Rowan students are developing an immersive, interactive and navigable tool using 3‐D virtual reality systems for modeling flooding and remediation in cities in Southern New Jersey.

The name “CAVE,” is both a recursive acronym (Cave Automatic Virtual Environment) and a reference to “The Simile of the Cave” found in Plato’s Republic, in which the philosopher explores the ideas of perception, reality, and illusion.Īpplications of the CAVE ® for Urban Environments The CAVE ® was designed at the University of Illinois in Chicago to be a useful tool for scientific visualization and can be coupled to remote data sources, supercomputers and scientific instruments via high‐speed networks. 1: Students simulate a NASA rocket engine test inside the CAVE ® at Rowan University. The real power of the CAVE ® environment is the ability to mix virtual reality imagery with real devices (like one’s hand, for instance).įig. Multiple viewers often share virtual experiences and easily carry on discussions inside the CAVE ®, enabling students and faculty to exchange discoveries and ideas. Instead, they put on lightweight stereo glasses and walk around inside the CAVE ® as they interact with virtual objects (see Figure 1). Unlike users of the video‐arcade type of VR system, CAVE ®‐users do not wear helmets to experience VR. The CAVE ® presents an immersive surroundscreen, surround‐sound virtual world which viewers can explore by moving around and grabbing objects using the data glove. The CAVE ® is a room sized, virtual reality (VR) environment inside which a group of users wear stereo glasses to visualize, navigate and interact with a 3‐D virtual environment that is created using a combination of digital light processing projectors, infra‐red precision‐position tracking system, data gloves and associated computer hardware and software.
