Drawing is hard, tracing is a lot easier. If you’re drawing something on the smaller end of the scale, tracing is an option but it’s not always accessible for large scale projects. SketchAR helps you trace anything on any size and all you need is a smartphone.
This app uses computer vision so you can paste a virtual image to a real life object. Like a piece of paper. In order to get this image to stay on the real piece of paper, grab a drawing tool, keep your eye on the phone and get to tracing.
This is a neat trick for small surfaces but where it really shines is on large ones. Want to draw a mural or do some awesome tagging? You can use this app to fake it if you can’t really make it. It’s available on Apple devices as well as Androids that are also running Tango.
