SATIN project merges haptic and 3D modelling

The system, developed as part of the pan-European Sound and Tangible Interferences for Novel Product Design (SATIN) project, combines 3D digital modelling with touch-sensitive haptic systems to allow designers to feel and shape creations virtually.

Prof Monica Bordegoni, who is leading the research, said: ’Designers use computer programs to create mathematically precise models of products, but they still need to be able to see and handle the model physically.

’Until now, the only way they have been able to do that is to turn to a model maker to create a real, physical sample. It’s a labour-intensive, time-consuming and costly process.’

Haptic technology takes advantage of the user’s tactile senses by using mechanics and special materials to transmit information through forces and vibrations.

The SATIN system incorporates this technology using two robotic arms, which position and rotate an electronic version of a robotic spline used to draw curves.
