Development, evaluation, refinement and distribution of software tools and techniques for application development, authoring and testing have been a direct emphasis of EVL’s research efforts over many years. Tools and techniques include computer-based models, simulations, data libraries, programming libraries and user interfaces. The libraries and user interfaces encompass visual, auditory, tactile and motion-based information displays.

Over the last decade, support for collaborative advanced visualization and networking applications has been a primary area of focus. Development of highly immersive visualization display devices and the middleware to create collaborative visualization environments has been the underpinnings for EVL’s work since the development of the CAVE™ in 1991; EVL developed a robust and virtual reality device-independent CAVE™ software library, CAVELib™.

Subsequently in 2000, EVL released CAVERNsoft G2, a toolkit for building collaborative networked applications or logistical networking applications, which then led to the development of the Scalable Adaptive Graphics Environment (SAGE). SAGE is a distributed computing architecture designed to allow users to share high-resolution imagery and high-definition video among groups of collaborators at local or remote sites.

Having been adopted by over 40 major institutions worldwide, SAGE refinement and “hardening” remains a crucial component of EVL’s research interests.
