  1. VR - The Historical ContextPart 2 Rudy Darken & Michael Zyda Naval Postgraduate School { Darken, Zyda }@cs.nps.navy.mil

  2. NASA Ames Research Center • Mike McGreevy and Scott Fisher developed the first affordable VE system in the mid 1980’s. • Their system consisted of a head-mounted display (their own design but contracted out to Leep Optics) and a VPL DataGlove (they contracted with VPL to build this under NASA’s specifications).

  8. NASA VIEW Project - Spatial Sound - the Convolvotron • The purpose of the Convolvotron was to provide 3D sound. • Small microphones were mounted in the ears of a dummy head. • Sounds were played at various positions around the head and the amplitudes and phase differences between the sounds arrivals at the microphones were recorded.

  9. NASA VIEW Project - Spatial Sound - the Convolvotron • Those parameters were used in the construction of a device, the Convolvotron, that could provide real-time, 3D positioning for sound that was otherwise not positioned. • i.e. the sound would be modified for the stereo channels to simulate the phase and amplitude differences that would exist “were” the sound really where the Convolvotron placed it. • This work was done by Beth Wenzel of NASA and Scott Foster of Crystal River Engineering...

  16. VPL Research • VPL produced the first commercial VR hardware and system (RB2). • VPL developed the DataGlove and PowerGlove and eventually a tactile feedback glove.

  17. VPL Research • They commercialized the NASA HMD technology - based on LCD displays and a special optics system. • Produced software for the design of virtual environments. • Produced a commercial VR system that can support one or two users.

  18. VPL’s Reality Built for Two (RB2) • A development platform for designing and implementing real-time virtual realities. • Development was rapid & interactive using a visual programming language. • Behavior constraints and interactions were edited in real-time.

  19. VPL’s Reality Built for Two (RB2) • Changes made to the interactions in the world were seen immediately. • For example, attach gravity to an object and see it fall.

  20. VPL’s Reality Built for Two (RB2) • RB2 consisted of 3 software modules and a variety of hardware. • The design & control workstation was a Mac II running a solid modeling application called RB2 Swivel and a data flow/real-time animation control package called Body Electric.
