Light Graffiti

Kitchen Budapest was commissioned by Magyar Telekom to create a playful installation for their 2012 roadshow. We came up with a simple idea that lets the users draw by waving their hands in the air.

Our software augments the users' gestural movements by an elastic physical simulation, similarly to Paul Haeberli's historical DynaDraw (graficaobscura.com/dyna/index.html) from 1989. Using the same technique that Haeberli applied to filter mouse positions, we acquired the user's hand from a Microsoft Kinect sensor that pulls on the brush with a synthetic rubber band.

The movement of the user generates sparking particles on screen. The dynamic filtering of the gestures creates smooth, calligraphic strokes, which are rendered in the Cinder (libcinder.org/) framework using OpenGL shaders.
