The recent widespread of multi-touch interactive surfaces
make them a privileged entertainment device. Taking ad-
vantage of such devices, we present an interactive LEGO application, developed accordingly to an adaptation of building block interactions and gestures for multi-touch tabletops.
Our solution (LTouchIt) accounts for bimanual multi-touch
input, allowing users to create 3D models on the tabletop
surface. Through user testing, we compared LTouchIt with
two LEGO applications. Results suggest that our interac-
tive application can provide a hands-on experience, more
adequate for entertainment purposes than available LEGO
applications, which are mouse based and follow a traditional single input interaction scheme.
