User interface designer R. Clayton Miller thinks the mouse and the windows-based desktop metaphor should die. It's just too confusing. However, he also argues that multitouch displays are not the answer. Looking at his solution, he may be right.

This video examines the benefits and limitations inherent in current mouse-based and window-oriented interfaces, the problems facing other potential solutions, and visualizes my proposal for a completely new way of interacting with desktop computers.

I recommend you watch the whole thing, because he makes some very good usability points—discussing the pros and cons of different UI approaches—before getting into his proposal—which looks beautiful and, more importantly, useful.

I like a lot of the things I see here. I like the way the applications are organized and accessed, combined a modal approach with a stream. I love how he solved the general menu vs application menu dilemma. What I don't like is the idea of having a control surface below the keyboard. I guess we are all used to it, through laptops and trackpads. And he is right that it may be a great way to transition to touch-interfaces for most users—because of that familiarity. However, I would like to see this implemented in a different form factor Both on the go—in the tablet—and in the desktop—in whatever new format the hardware manufacturers can come up with.
