Low-Cost Part-Task Flight Training System: An Application of a Head Mounted Display.

摘要

To investigate the feasibility of using head-mounted display(HMD) and Computer Image Generators(CIG) in a low cost part-task trainer, we created a prototype system. Our approach was to build a virtual world interface using a HMD to an existing flight simulator application. This allowed a CIG with only one graphics channel to drive the display. To investigate which class of computing platform was suitable for use as the CIG, a cooperative thesis effort was launched to host the simulator on a mini-computer and micro-computer platform. The appropriate CIG could then be determined through demonstration and comparison between the systems. A software emulation library was built to transform the Silicon Graphics graphical reference model and function calls to the PC Reality PHIGS PLUS graphical reference model and function calls. This emulation allowed a nearly seamless interface to support porting the application program from the Silicon Graphics machine to the PC. Keywords: Theses. (emk)
