ABSTRACT
The uses of virtual environments (VEs) raise a variety of cognitive issues. Virtual environments provide information to users, and, in many cases, they provide users with the ability to interact with the environment in response to the information that the environment conveys. Many different cognitive factors play roles in the use of VE applications. These include issues related to perception, attention, learning and memory, problem solving and decision making, and motor cognition. Research and experimental applications of virtual environments have clarified some cognitive aspects of VE usage, but many questions have been raised for further research.
