Mission Statement

"Our mission is to accelerate the development of technologies that allow intuitive, efficient access, manipulation, and exchange of complex information by facilitating the creation of measurement methods and standards."

We contribute to the advancement of these technologies, as well as enable faster transition into the commercial marketplace and into applications of our sponsors, through

  • Performance metrics, evaluation methodologies, test suites and test data
  • Prototypes and testbeds
  • Workshops
  • Standards and guidelines

We do this in collaboration with industry, academia, and government.
