I'm trying to dig up some guidelines for implementing double-click. I can and have searched teh internets and consulted, e.g., The Essential Guide to UI Design. :) I also know most of the principles and can derive from what the OSes and such do as well as the next person.
I say all that in hopes of focusing replies--I'm specifically looking for references based on testing and/or real-world practice.
In helping my boyfriend prep for upcoming interviews, I stumbled across
dontclick.it. The experience was a little jarring at first as I kept
hitting the back button while navigating through the site and even
attempted to <gasp!> click on a few 'links'. This is the complete
opposite experience of what they are trying to achieve; the navigation
scheme is structured such that the application shifts its content as the
user moves their mouse, avoiding the use of mouse buttons.
