Line Lab is a playful tinkering tool that turns hand-drawn symbols into digital components visualized through augmented reality. We trained a bespoke machine learning model to detect and classify drawings from a preordained dataset, and used AR to overlay interactive 3D assets atop them. This results in a surprisingly intuitive tangible user interface that people of various ages could engage with almost immediately.

Our initial concept of Line Lab explored the potential of this technology as an education tool that combined Do-It-Yourself (DIY) cardboard components and AR, allowing children to design and iterate their own robots quickly without needing expensive kits. Prototypes were validated with educators, children, and parents in various spaces including a local youth club, maker space, and a major London science festival through workshops and interactive booths. The project was well received by a wide range of participants, expressing desire to see this project grow.
