LEGO Flow

LEGO Flow is a simple but playful interactive table. Children and playful adults can interact with an endless stream of virtual LEGO bricks by blocking their paths using finger tracking, or by placing physical LEGO bricks on the table, to act as color “magnets” that attract all the virtual bricks of a particular color. CAVI designed this installation to demonstrate the features of a 55" Intel Multi-touch screen that uses finger tracking and marker tracking as inputs. Finger tracking makes it possible for several children to simultaneously build virtual bridges of red LEGO bricks, by touching the screen. Additionally, a set of physical LEGO bricks in different colors works by means of marker tracking, acting like magnets in the sense that they only attract the virtual LEGO bricks of the same color as the physical brick, making it possible to connect a physical yellow LEGO brick with the virtual yellow LEGO bricks flowing across the table. Children are able to either strengthen the magnetic effect and attract all the yellow bricks, or reverse polarity, making it repel the yellow bricks.

LEGO Flow demonstrates how this table makes it possible for children to invent games using their fingers and the LEGO bricks, by offering simple and intuitive interaction.

LEGO Flow was one of CAVI's installations at LEGO World 2012, and received considerable attention from the visiting children. Among the other installations was a new version of the Radartable, based on visuals and sounds from the LEGO universe.
