The objective of the NIST Web Metrics Testbed is to explore the feasibility of a range of tools and techniques that support rapid, remote, and automated testing and evaluation of website usability. The prototypes are used to support the usability engineering research of the Visualization and Usability Group (VUG). As part of the Information Access Division of the Information Technology Laboratory at the National Institute of Standards and Technology, VUG encourages industry to use and/or commercialize its ideas.
