Guimbretiere explores how to bridge the gap between the power provided by current desktop computer interfaces and the fluid use of whiteboards and pin-boards. Observing fluid expert interactions in everyday life, such as driving a car or playing a violin, his team has designed, and built a fluid interaction framework which encourages gesture memory, reduces the need for dialog with the user, and provides a scoping mechanism for modes.   To validate their design, they built the Stanford Interactive Mural, a 9 Mpixel whiteboard-size screen, evaluated the performance of their proposed menu system FlowMenu, and implemented PostBrainstorm a digital brainstorming tool. PostBrainstorm lets users gather and organize sketches, snapshots of physical documents, and a variety of digital documents on the Interactive Mural. PostBrainstorm was very well received by professional designers during testing, and was used in the early design stage of the Chrysler Design Award 2001. It demonstrates the feasibility of fluid, transparent interactions for complex, real life applications. From the Series:CSE Colloquia - 2002
