Empowering Children to Create AI-Enabled Augmented Reality Experiences
This paper presents Capybara, an AI-powered visual programming environment that empowers children to create, customize, and animate interactive 3D augmented reality experiences by leveraging generative AI for character creation and computer vision for bridging virtual and physical worlds, as validated by user studies in the US and Argentina.

Imagine the digital world as a giant, magical playground where the rules are written in code. For years, kids have been able to build castles and race cars in this playground using tools like Scratch, which lets them snap together colorful puzzle pieces instead of typing complex instructions. But there's a catch: most of these digital worlds stay trapped inside the screen. They can't see the real world around you, and they can't react to the coffee cup on your desk or the dog walking by your feet.
Now, imagine if that digital playground could reach out, touch the real world, and change based on what it sees. This is the magic of Augmented Reality (AR), which is like wearing special glasses that let you see digital characters floating right on top of your real living room. And if you add Artificial Intelligence (AI) to the mix, it's like giving those digital characters a brain so they can understand what they are looking at. The big question researchers are asking is: Can we hand the keys to this magical, brainy playground to children? Can we let them not just play with these smart digital worlds, but actually build them, mixing their imagination with real-world objects?
This is exactly what a team of researchers set out to do with a new tool called Capybara. Think of Capybara as a "Lego set for the future," but instead of plastic bricks, you use voice commands and body movements to build. The researchers built an app for tablets that lets kids create their own 3D characters, make them dance, and program them to interact with real objects like bananas or keyboards.
Here is how it works: First, a child can talk to the app and say, "I want a capybara wearing a wizard hat," and the AI instantly draws a 3D version of it. Next, the child can stand up and wave their arms; the app watches their body and makes the digital character copy the moves, like a puppeteer controlling a marionette. Finally, the child can use "sensing blocks" to tell the character, "If you see a banana on the floor, jump over it." The app uses its camera to spot the real banana and makes the digital character react to it.
The team tested this with 20 children, aged 7 to 16, in the United States and Argentina. They found that the kids could successfully use Capybara to create these mixed-reality stories. The children loved the freedom to make their characters look exactly how they imagined and to make them dance to their own moves. They felt like they were building something truly unique, bridging the gap between their physical room and a digital world.
However, the researchers also noticed some bumps in the road. Sometimes the AI would get a little confused. If a kid asked for a specific type of hat, the AI might make one that looked a bit weird, which frustrated the children. Also, some kids got so excited trying to get the AI to draw the perfect character that they forgot to finish the story they were trying to tell. The study suggests that while this tool is a fun and powerful way for kids to learn about coding and AI, it needs a little more guidance to help them stay focused and to handle the AI's occasional mistakes.
In short, Capybara suggests that children are ready to be the architects of smart, interactive worlds, but they need tools that are as patient and clear as they are creative. It's a promising step toward a future where kids don't just consume digital content, but create their own magical realities that live right alongside the real world.
