There’s a little artistry in everyone, but not everyone has the time to sit down and practice drawing hands for hours and hours. Why not cheat a little? SketchAR is essentially AR tracing — plot a couple of circles on a piece of paper and choose a sketch, and SketchAR will project that image onto the paper, allowing you to trace around it. It’s not exactly tracing, as you’ll struggle to properly match the lines perfectly, but it works very well if you’re looking to practice specific drawing techniques.
SketchAR can be a little awkward — holding a phone in one hand and drawing with the other is not exactly a natural position — but it’s worth a try. It works with small pieces of paper on most ARCore-capable phones. It’s available for Android, iOS, and Microsoft’s HoloLens headset.
