NASA VIRTUAL GLOVEBOX: AN IMMERSIVE VIRTUAL DESKTOP ENVIRONMENT FOR TRAINING ASTRONAUTS IN LIFE SCIENCE EXPERIMENTS

摘要

The International Space Station will soon provide an unparalleled research facility for studying the near-and longer-term effects of microgravity on living systems. Using the Space Station Glovebox Facility - a compact, fully contained reach-in environment -astronauts will conduct technically challenging life sciences experiments. Virtual environment technologies are being developed at NASA Ames Research Center to help realize the scientific potential of this unique resource by facilitating the experimental hardware and protocol designs and by assisting the astronauts in training. The "Virtual GloveboX" (VGX) integrates high-fidelity graphics, force-feedback devices and realtime computer simulation engines to achieve an immersive training environment. Here, we describe the prototype VGX system, the distributed processing architecture used in the simulation environment, and modifications to the visualization pipeline required to accommodate the display configuration.
