State-of-the-art virtual reality hardware for computer-aided design

Virtual reality is an exciting new held which may offer significant improvements in the efficiency of human-computer interface for a wide variety of computer applications. This paper serves to identify technology developments in virtual reality hardware devices that may allow for development of a more efficient user interface for computer-aided design packages for mechanical design functions. Presented is a survey of the current state of the art in the rapidly changing field of virtual reality hardware devices. The devices are broken down into classes that are related to user interface features that may improve the efficiency of computer-aided design functions. Classes of virtual reality hardware devices are identified needing future research and development to implement the most effective virtual reality computer-aided design interface.
