Cognitive Dimensions of Notations
Resource Site



The Cognitive Dimensions of Notations (CDs) framework is an approach to analysing the usability of information artefacts: these are often software systems, but also include many other things that people interact with, including those made out of plastic and paper. CDs can be applied to discover useful things about usability problems that are not easily analysed using conventional techniques from Ergonomics or Human Computer Interaction. They are being used by many researchers around the world, and in the last few years they are also being adopted by commercial product designers.

This page aims to be a central directory of links to CD resources, publications and research.
