A head-worn augmented reality system is being developed for use in military and commercial aircraft assembly and maintenance . We are also interested in the perceptive modes ( haptic and visual ) involved in the interaction with virtual reality systems . For a number of practical reasons related to available equipment , software and expertise , Apple 's QuickTime Virtual Reality system is being used . These include , but are not limited to , image processing applications in synthetic aperture radar ( SAR ) , real-time tasking of multi-sensor platforms , dynamic target recognition , virtual reality systems , and rapid searches of extremely large databases . Fixation disparity changes have been reported previously ( Mon-Williams et al. ) but our results suggest that it is likely that these were specific to the equipment used in their experiment , rather than being a general problem with Virtual Reality systems per se . Furthermore the combination of collaboration platforms with mobile , multi-user augmented reality systems will lead to a new forms of cooperation support in the office as well as the manufacturing environment . GeoWall is a low-cost virtual reality system that is being used by several colleges on campus . “ We ’ re trying to use this CAVE virtual reality system to assist in the design of the next class of DD ( X ) destroyers , ” says Shreekanth Mandayam , the professor of electrical and computer engineering at Rowan , leading the team of student researchers . Rendering photorealistic virtual objects from their real images is one of the main research issues in mixed reality systems . By considering the distribution of a virtual reality system , this project attempts to understand how the lessons learned for the management of audio and video data on the Internet scale to address the requirements for other continous media types , such as display lists , user 's position and orientation tracking reports , and instrument control message streams .
