DESIGNi: a workbench for supporting interaction design

New devices expand design possibilities, but also lead to more challenges in the creation of interaction forms. This article introduces DESIGNi, a workbench that supports designers in exploring interaction forms and their attributes in a structured and systematic way. We present the components of DESIGNi and its use in creating a business application. Moreover, a comparison of the interaction forms specified in the design process with DESIGNi and the perceived interaction characteristics in user studies revealed interesting insights and points for improvement in the interaction design itself.
