Digitally assisted stereo drawing

International audienceWith the increasing range of available stereoscopic rendering devices, stereoscopic images and videos are reaching the general public. Creating such pairs of images digitally from 3D content is easy to tweak and adjust. On the other hand, drawing directly stereoscopic scenes on a sheet of paper is very hard to perform. In this paper, we focus on such an interactive task where interactive 3D graphics and novel user interfaces are combined together to create stereoscopic drawings from a standard pen and paper interface. Our system is based on augmented reality, multitouch, and 3D spatial interaction, to enhance interaction with the 3D scene. The projection of the left and right views on the paper guides the users in their stereoscopic drawing task, while maintaining a high level of expressiveness. This work is a first step towards promising full applications for interactive drawing of 3D stereoscopic images
