In evaluating the state of technology for extracting information from natural language text by machine, it is valuable to compare the performance of machine extraction systems with that achieved by humans performing the same task. The purpose of this paper is to present some results from a comparative study of human and machine performance for one of the information extraction tasks used in the MUC-5/Tipster evaluation that can help assess the maturity and applicability of the technology.

: This report reviews current interface technology for use in virtual environments. Visual, tracking, auditory, primary user input (including, for example, glove, body suit, exoskeleton, track ball, and 3-D mouse inputs), tactile, kinesthetic, full-body motion, and olfactory interface technologies are covered. In each case, the relevant human capabilities are discussed, followed by descriptions of some available commercial products and ongoing research and development efforts. This information is used as the basis for predicting how virtual environment interfaces are likely to change in the next five years.
