I’ve recently launched a website for the new Context Toolkit that I’ve adapted from the original one built by my advisor, Anind, years ago. Visit www.contexttoolkit.org to learn more. There you can download v2.0 of the toolkit, and learn how to use it from tutorials there. The Intelligibility Toolkit is also now available for download as part of the Context Toolkit. Tutorials for how to use its various components are also located on the website.
