Hayaku

Abstract

Although reactive and graphically rich interfaces are now mainstream, their development is still a notoriously difficult task. This paper presents Hayaku, a toolset that supports designing finely tuned interactive graphics. With Hayaku, a designer can abstract graphics in a class, describe the connections between input and graphics through this class, and compile it into runnable code with a graphical compile chain. The benefits of this approach are multiple. First, the frontend of the compiler is a rich standard graphical language that designers can use with existing drawing tools. Second, manipulating a data flow and abstracting the low-level run-time through a front-end language makes the transformation from data to graphics easier for designers. Third, the graphical interaction code can be ported to other platforms with minimal changes, while benefiting from optimizations provided by the graphical compiler.
