The recent widespread of multi-touch interactive surfaces make them a privileged entertainment device. Taking advantage 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 interactive 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.
