KDE e.V. Human Computer Interaction Working Group
To create a more compelling, usable, understandable interface for all people.
The KDE Human Computer Interation (HCI) Working Group was formally organized in March, 2006. While it existed for a little over two years, the group disbanded in April 2008 due to inactivity. The firstname.lastname@example.org mailing list is still operating informally.
See the original announcement of the working group for details.
