As expected, the STTR Phase I investigation confirmed that the Digital Virtual Human (DVH) and Robonaut technologies can be merged, and that haptic and autostereoscopic technologies can be integrated in the robotic control systems, effectively and productively. This feasibility study verified and validated interactions of Robonaut with the DVH in operator response to and performance with haptic devices and autostereoscopic displays. Phase II will focus on developing two significant components from the Phase I effort for marketing and distribution in Phase III. The Collaborative-Virtual Environment Software Toolkit (C-VEST) will provide software developers a potent development toolkit with which to build and maintain 3D/VR applications and simulations. As a result of Phase II, the C-VEST product will be able to interface with immersive simulation (motion capture, manipulation, navigational, and advanced display) hardware not easily implemented in current commercial or academic 3D/VR software. The second product emanating from this Phase II project will be the OpticFlex full-body fiber-optic-based motion-capture system. This system will comprise a significant part of the Phase II and subsequently Phase III commercialization preparation effort.
