This paper describes ICON, a novel editor designed to configure a set of input devices and connect them to actions into a graphical interactive application. ICON allows physically challenged users to connect alternative input devices and/or configure their interaction techniques according to their needs. It allows skilled users - graphic designers or musicians for example - to configure any ICON aware application to use their favorite input devices and interaction techniques (bimanual, voice enabled, etc.). ICON works with Java Swing and requires applications to describe their interaction styles in terms of ICON modules. By using ICON, users can adapt more deeply than before their applications and programmers can easily provide extensibility to their applications.
