In the Details: Building a 3D Sketchpad That Lets You Draw Objects in Midair
Posted in: In the Details
With the rise of augmented reality (AR) technology, virtual reality headsets like the much buzzed-about Oculus Rift aren’t just for playing games in a simulated universe—they can actually help industrial designers do their jobs, too. Four students at the Royal College of Art recently suggested how with Gravity, a 3D sketchpad that they debuted at an RCA exhibition last February.
Right now Gravity exists as a functioning prototype—and it works pretty much exactly how you would imagine. Users don virtual reality glasses and then draw objects in space above the Landing Pad, a handheld glass platform. This space above the Landing Pad is called “GSpace,” and it can be comprised of a single drawing or multiple ones. By rotating or tilting the Landing Pad, the user can control the plane the drawing exists on and build out the drawing, much like adding details to a real object in space.
Gravity works by integrating several tracking technologies to be able to pair and synchronize all of the different elements of the system together with the AR glasses, so that the 3D-generated content is overlaid on top of the user’s vision in real time. The team has a patent pending on its innovation.
The Gravity team—Guillaume Couche, Daniela Paredes Fuentes, Pierre Paslier and Oluwaseyi Sosanya—is currently finishing the beta software and looking for manufacturers for the Landing Pad and the pen. Users will have to provide their own virtual-reality headsets; the developers have been working with AR glasses by the French company Laster, but they’re aiming for universal compatibility. “We have recently made our software compatible with Oculus Rift and we are looking into making it work with all the leading-edge AR glasses on the market (that is, with on-board camera and LARGE field of view for immersive AR),” the Gravity team writes in an e-mail. “Gravity is a tool where augmented and virtual realities can be exploded as creation tools. This is why we are trying to make it available for as many platforms as possible. Our idea is to become the universal platform for 3D sketching in AR.”
