There’s a lot of tracing naysayers out there who say it’s “cheating,” or that it doesn’t actually help you learn to draw, but I beg to differ. The best way to learn to draw is by doing, and if it takes using a lightbox or a projector toy to get started, so be it!
SketchAR is the latest iteration of the augmented reality drawing concept that hit the App Store yesterday, and will soon be coming to Android Tango and Microsoft HoloLens. It works by laying out a virtual image on the paper you’ll be drawing on, which is displayed on your phone screen. It’s pretty difficult to use it as shown in the promo video — i.e., holding the phone in one hand while tracing over the virtual lines with the other — so using a tripod would be ideal.
