LTouchIt

A couple of months ago my master student Daniel Mendes defended his thesis with honorable success (19/20). In his master work he developed an interactive tabletop LEGO modelling application (LTouchIt), which has been presented at the ACE 2011 conference. Below is a short video demonstrating the prototype.
