The Infrastructure of Command Information Systems
Abstract
Our primary objective of the head mounted display is the exploration and development of dynamic interaction techniques between human users and computer-generated virtual worlds. This interaction depends upon the image of the virtual world responding to the user's movements in the same manner that the user's view of the real world does. An optical head tracking system has been developed that is easily scalable in size, has an update rate of 20-100 Hz with 20-100 milliseconds of lag, and resolves head motions of 0.080 in. and 0.2 deg. The system adopts an inside-out optical tracking paradigm. The objective of Pixel Planes 5 has been to design and to build multicomputer architecture (both hardware and software) for three dimensional interactive graphics that delivers in excess of one million polygons per second to real applications and that supports a wide variety of rendering algorithms. We developed and refined a prototype software system enabling a user to walk through a virtual building in real time and to get rather good visual aural impressions of how the spaces will feel. We have developed new tools and methodology for studying how people work with computers. By understanding users' strategies and behaviors better, we can, in turn, build computer systems that more closely match the way they think and work. A portion of this contract has sponsored work aimed at the understanding, simplication, and application of data-parallel programming techniques to program these machines.
