Six 60“ displays and an extra large primeTOUCH system created a massive multi-touch wall at ISE 2012, Europe’s largest exhibition for audiovisual technologies. We realized this interactive application, which transformed visitors into graffiti artists, in cooperation with Lang AG. Next to virtual spraying, the wall also offered an interactive game and the option to leave post-it notes. Via two integrated cameras visitors could take pictures of themselves, add text and ‘stick’ the pictures to the wall. Cool sound effects and a lot of attention to detail turned this installation into a real show-stopper.
