SketchAR is an application through which the user sees a virtual image on the surface of which they are planning to trace a sketch. It is designed to help people who have always wanted, but could not draw. This iteration of the App is using depth sensors that currently only a few special phones have. These sensors are being developed by Google under the name Project Tango and enable a mobile device to become aware of its physical location in the world. SketchAR uses this new spatial information in combination with augmented reality for large scale drawings, stencils and graffiti.
