| has gloss | eng: The Jack human simulation system was developed at the Center for Human Modeling and Simulation at the University of Pennsylvania in the 1980s & 1990s. Conceived as an ergonomic assessment and virtual human prototyping system for NASA space shuttle development, it soon gathered funding from the U.S. Navy and U.S. Army for dismounted soldier simulation, from the U.S. Air Force for maintenance simulation, and from various other government and corporate users for their own applications. In 1996 the software was spun off into a privately held company and is now sold as an ergonomic human simulation toolkit (called Tecnomatix Jack) by Siemens. The research and development of the Jack system have let to such standards as H-anim and MPEG4 Body Animation Parameters. |
