Hands-on interactive tabletop LEGO application

ABSTRACT

Presently, multi-touch interactive surfaces have widespread adoption as entertainment devices. Taking advantage of such devices, we present an interactive LEGO application, developed accordingly to an adaptation of building block metaphors and direct multi-touch manipulation. Our solution (LTouchIt) allows users to create 3D models on a tabletop surface. To prove the validity of our approach, we compared LTouchIt with two LEGO applications, conducting a user study with 20 participants. The results suggest that our touch-based application can compete with existing mouse-based applications. It provides users with a hands-on experience, which we believe to be more adequate for entertainment purposes.
