Using HTC Vive and TouchDesigner to Projection-Map Moving Objects in 3D Space

Abstract

We present the first public exhibition that uses HTC Vive and TouchDesigner to projection-map moving objects in real-time in 3D space. Our case study is an exhibition of the media artwork "The Playground". During this exhibition we involved the public. They found small sculptural pieces that were hidden in public areas, they brought these pieces to an exhibition space and connected them onto a central sculpture. People could also take a photo of their city environment and upload it to a webpage. When a person entered the exhibition space our system projected this person's photo onto the small sculptural piece that was in their hand. Our system tracked and projected onto this piece as it moved around an exhibition area. All of the public's photos were also projection-mapped onto a co-created central sculpture. Our contribution benefits designers, artists and researchers who want to make playful experiences that involve projection-mapping moving objects in real-time in 3D physical space using relatively inexpensive, easily accessible tools.
