DisplayObjects: A designer workbench of interactive styrofoam
DisplayObjects, by Eric Akaoka, is an organic user interface for creating computer displays on arbitrary surfaces, such as pieces of model cardboard or blocks of styrofoam. It allows easy prototyping of hardware gadgets through software/hardware fusion. The system tracks the location of the model, as well as the finger, via markers tracked through computer vision, and renders a 3D software model of the object back onto the hardware model through projection.
