Monet
Informal Prototyping of Continuous Interactions by Demonstration
Informal prototyping tools have shown great potential in facilitating the early
stage design of user interfaces. However, continuous interactions, an important
constituent of highly interactive interfaces, have not been well supported by
previous tools. These interactions give continuous visual feedback, such as
geometric changes of a graphical object, in response to continuous user input,
such as the movement of a mouse. We built Monet, a sketch-based tool for
prototyping continuous interactions by demonstration.

In Monet, designers can prototype continuous widgets and their states of
interest using examples. They can also demonstrate com-pound behaviors
involving multiple widgets by direct manipulation. Monet allows continuous
interactions to be eas-ily integrated with event-based, discrete interactions.
Continuous widgets can be embedded into storyboards and their states can
condition or trigger storyboard transitions. Monet achieves these features by
employing continuous function approximation and statistical classification
techniques, without using any domain specific knowledge or assuming any
application semantics. Informal feedback showed that Monet is a promising
approach to enabling more complete tool support for early stage UI design.
