    GIDes ++
    (The Eurographics Association, 2021) Jorge, Joaquim; Silva, Nelson; Cardos, Tiago; Marcos, Adérito and Mendonça, Ana and Leitão, Miguel and Costa, António and Jorge, Joaquim
    GIDes ++ is a gesture based calligraphic 3D modeller using expectation lists, and extends the notion of natural and efficient interface. A brand new look and a new modeller kernel empower the modelling capabilities. A measures layer enables the user to visualize and change measures, giving a new dimension in precise and accurate modelling. Adding new modalities like handwriting and speech, GIDes ++ present a natural and intelligent multimodal interface enabling quick models prototyping creation. Visually, much effort is being made to create a more appealing and elegant application, but keeping always in mind the usefulness of these visual effects.

    Task Analysis and Scenario-Based Design of Calligraphic Interfaces
    (The Eurographics Association, 2021) Dias, Filipe; Fonseca, Manuel; Jorge, Joaquim; Marcos, Adérito and Mendonça, Ana and Leitão, Miguel and Costa, António and Jorge, Joaquim
    The great functionality of today's CAD systems enables the manufacturing of very complex models. Yet, great part of this power is unusable, early in the design process. As well, we have found two different approaches in two different car designers that surprisingly lead to the same long time in development. In this paper we identify the reasons for these problems, and propose a solution that bridges the different worlds of conceptual and geometric models, using the affordability of the calligraphic interface. Creating a prototype by drawing it allows impossible situations to be immediately identified and corrected, without further communication overheads, certifying that emotional drawing ideas correspond to the designer's intents.
