Coming to an event near you: virtual graffiti

Although street art is experiencing a renaissance, the old issue of vandalism remains. YrWall is an interactive virtual graffiti wall that avoids the drips and damage because, quite simply, there’s no paint involved. Users paint on a projection screen using a can that’s actually an infra-red beam controlled by a button and tracked using a computer vision system. By pressing the faux spray can’s button, users draw on the wall much like using their computer’s draw function, but without the mouse and on a much larger scale. A pop-up interface provides an array of digital paint colours and also allows users to select themes like nature or urban; grabbing images from these themes to add to their piece.
