Development of gesture interaction requires a combination of three design matters: gesture, presentation, and dialog. However, in current work on rapid prototyping the focus is on gestures taking into account only the presentation. Model-based development incorporating gestures, in contrast, supports the gesture and dialog dimensions. The work on ProGesture aims at a rapid prototyping tool supporting a coherent development within the whole gesture-presentation-dialog design space. In this contribution, a first version of ProGesture is introduced. Here, gestures are specified by demonstrating the movements or they are composed of other gestures. The tool also provides a dialog editor, which allows gestures to be assigned to dialog models. Based on its executable runtime system the models and gestures can be tested and evaluated. In addition, gestures can be bound to first presentations or existing applications and evaluated in their context.
