This work is devoted to introduce a new Bi-manual system that provides an handful user interface for free-form surface modelling. The Bi-Manual user interface (Bi-Manual-UI) has been realized exploiting a 6DOF (degree-of-freedom) motion controller. The system considers the integration of a motion controller with a pen based graphical tablet. The Bi-Manual-UI aims to increase the interaction with users enhancing the creation of complex shapes. A sketching plane is available to users who can control its 3D position by the motion controller. In the meanwhile, users can draw a section curve on the plane, using the pen tablet. Moving the plane into a 3D space, the set of created curves area used to generate interactively the free-form surface. Unlikely standard CAD systems, the developed framework enables to change the sectional curve in real-time leading to the creation of shapes with different sections. Advantages introduced by this innovative instrument consist in the usage of it as a true geometric modelling tool and not only in order to move and rotate virtual camera.

Abstract
This work is devoted to introduce a new Bi-manual system that provides an handful user interface for free-form surface modelling. The Bi-Manual user interface (Bi-Manual-UI) has been realized exploiting a 6DOF (degree-of-freedom) motion controller. The system considers the integration of a motion controller with a pen based graphical tablet. The Bi-Manual-UI aims to increase the interaction with users enhancing the creation of complex shapes. A sketching plane is available to users who can control its 3D position by the motion controller. In the meanwhile, users can draw a section curve on the plane, using the pen tablet. Moving the plane into a 3D space, the set of created curves area used to generate interactively the free-form surface. Unlikely standard CAD systems, the developed framework enables to change the sectional curve in real-time leading to the creation of shapes with different sections.
