For some time, I've been intrigued by the question of what comes next
after the mouse and the windowed desktop, the Xerox PARC legacy of
desktop human-computer interaction. The paradigm that PARC gave us
has proven amazingly versatile. But even it has its limitations, both
in navigability and interaction bandwidth.
Over a span of about nine months, I pulled together some casual
research here and there, examining other proposals, trying to
determine their shortcomings, and, in the realm of thought
experiment, iterated answers to the problems that I identified.
