Facebook’s $2 billion acquisition of Oculus Rift has reopened conversation about the potential of virtual reality, but a key question remains: How will we actually interact with these worlds? Minecraft creator Markus Persson noted that while these tools can enable amazing experiences, moving around and creating in them is far from a solved problem.

Their high-tech sketchpad looks a bit like a prop from Tron, with its etched grid of transparent plastic and sternly rectilinear user interface panel, but the goal is to make augmented reality feel as natural and organic as sketching in a notebook. Artists hold the acrylic drawing tablet like its analog counterpart and sketch with a custom stylus. Radio frequency sensors record the movements and coordinates on the pad and send them to an Arduino hidden in the black box on its edge.
