Goal and Motivation Seek successor to UI using

Desktop metaphor Hardware prices dropping,

performance rising What is there aside from WIMP

Strategies Making User workspace larger Enabling user interaction with

multiple Agents Increasing real-time interaction rate

between user and system Provide visual abstraction to speed

information assimilation and retrieval

Workspace More screen space. Rooms.

Multiple desktops. Denser screen space. Animation

and 3D.

Strengths Formalizes and defines tasks that a

next-generation 3D Animated UI would have to perform.

Weaknesses Sorry. The “future” didn’t happen

as envisioned. The desktop paradigm, augmented

with the “web paradigm” survives. WIMP still rules.

Favorite Sentence In the 1990’s, it is likely that

information access will be a primary force in shaping the successor to the desktop metaphor.
