Interactive 3D Display System

Standard CRT display technology does not work well in Lofargram analysis. CRTs induce fatigue which reduces user effectiveness. This program proposes use of a new computer interface device which allows both the generation of more effective (data-rich) displays and faster more intuitive interaction between display and operator. The basis of the interface device is location of the operator\'s point of attention in 3-space using eye-tracking. The program also proposes to measure visual fatigue using eye-tracking. In Phase I a prototype improved Lofargram display will be developed as a proof-of-principle testbed for the utility of these concepts. A display based on these principles fusing data from multiple sonar sensors is proposed for Phase II development.
