UIST 2007 Panel Discussion Paper How should we evaluate new user interface

systems so that true progress is being made?

Force for change Value added by UI systems architecture

◦ Reduce development viscosity◦ Least resistance to good solutions◦ Lower skill barriers◦ Power in common infrastructure

The Usability Trap The Fatal Flaw Falancy The Legacy Code

STU Importance (of STU) Problems not previously solved Generality Reduce solution viscosity

◦ Flexibility◦ Expressive leverage

Expressive Match

Empowering new design participant Power in combination

◦ Inductive combination◦ Simplifying interconnection◦ Ease of combination

Can it scale up?
