AR Doodle

AR Doodle is an augmented reality app that allows you to draw in 3D in the air using your smartphone's camera. With it, you can merge your physical environment with digital strokes, providing you with an infinite canvas where your doodles, messages, and geometric shapes remain floating in the air or anchored to the faces of the people you capture on video.

Drawing modes and spatial anchoring

When you open the camera from the interface, you will discover two main ways of interacting with the environment. The first mode is focused on facial recognition; you can draw virtual glasses, a hat, or a mustache on a person, with the algorithm ensuring that those strokes follow their head movements with amazing precision, reminiscent of the dynamic filters offered by other apps but created entirely by you. The second mode scans the room you're in to anchor your creations in physical space. This means that you can write a floating message in the center of your living room, walk around it, and see how the letters maintain their exact position and 3D perspective, allowing you to explore your drawings from any angle as if they were real sculptures.

Brushes, stroke settings, and recordings

To bring your ideas to life, you will have a very versatile and easy-to-configure creation palette at your disposal. You will have access to various brush styles that react to your movement through space, including glowing neon lines that stand out in the dark, or strokes with watercolor textures, thick markers, or sparkling effects. You can adjust the thickness of each line and select colors from a full color wheel before you start recording. The beauty of all this is that the final result is not just a static photo, but rather a short video showcasing your art. While you walk around and interact with your 3D figures, you can capture the action in real time, record your voice in the background to narrate what you're doing, and save the clip directly to your device's gallery to share it.

My experience with AR Doodle

When testing this app on my Samsung smartphone, I had a great time with the drawings I made in augmented reality. I started by drawing neon wings on my dog's back and recorded a video while he walked down the hallway; I found it funny how the strokes maintained their position in the air even though I was moving the camera. I also messed around with the different brush thicknesses to write my name in 3D on the dining room table, then walked around the letters. The facial recognition responds almost instantaneously, although it sometimes struggles a bit with dim lighting or when there's a lot of backlighting. If you use the app for a long time, your device will heat up, especially if the brightness is maxed out.

What I liked most about AR Doodle and what could be improved

· What I liked most: the precision of the spatial anchoring that allows you to walk around your 3D drawings and the wide variety of dynamic brushes.

· What I would improve: the device heating up during long sessions and the facial recognition struggling in low-light environments.
