`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 .

`PREFACE
`
`This report presents a review of virtual environment interface technology from the
`perspective of the user, that is, the devices and requirements that are imposed on the user in
`order to interact with a virtual environment. Most of the work was performed as part of a
`Central Research Project, Research and Development in Virtual Environments, with some
`additional support provided by Task A-183, Virtual Reality Assessment of the Technical
`Capabilities of Surgeons and Task T-L2-1278, Cost and Effectiveness of Multimedia Train(cid:173)
`ing Technologies.
`
`The report was reviewed by the following staff members at the Institute for Defense
`Analyses: Mr. Robert L. Clover, Ms. Anne A. Douville, Dr. Dexter Fletcher, Dr. Richard
`J. Ivanetich, Dr. Michael R. Kappel, and Ms. Julia J. Loughran.
`
`The authors gratefully acknowledge the support provided by all those who took
`time from their busy schedules to discuss their products and their work .
