early head-mounted display device — virtual reality Early head-mounted display device developed by Ivan Sutherland at Harvard University, c. 1967.

NASA's Virtual Visual Environment Display (VIEW) workstation, completed in 1985 at the Ames Research Center, established a standard suite of virtual reality technologies. The workstation incorporated the following components:

Stereoscopic head-coupled display: A head-mounted device used to provide immersive visual output.1
Head tracker: Technology that monitored the user's head movements to adjust the generated images in real time.1
Speech recognition: An interface allowing for voice-based interaction.1
Computer-generated imagery: The graphical output used to construct the virtual environment.1
Data glove: An input device that enabled the user to interact with and manipulate virtual objects.1
3-D audio technology: Systems designed to provide spatialized sound within the virtual environment.1

The VIEW project was directed by Scott Fisher and aimed to create low-cost, personal simulation environments for applications in telerobotics, scientific research, and education.1
