Natural modelling of interactive applications

This paper presents an approach, and the associated environment, aiming to support designers to intuitively model interactive applications. The goal is to make modelling activity more natural. The approach is based on a transformation able to convert hand-drawn visual model sketches on boards into task-model specifications that are further editable and analysable through automatic visual tools. A first test of the environment has been carried out and has provided useful suggestions about how to improve it.
