About

Yuhan Lin is a leading researcher in child-robot interaction and tangible programming for early childhood education. Their work centers on designing accessible, developmentally appropriate programming tools that bridge the gap between young learners and computational thinking. Lin’s most significant contribution is the development of the VEX 123 platform, a robotic system that supports multiple programming modalities—from button-based commands and tangible Coder cards to more advanced interfaces—enabling children as young as five to engage with programming concepts. Their 2023 paper, “It’s as Easy as 123,” demonstrates how a single device can serve users across the entire novice-to-professional spectrum, a novel approach in educational robotics. Lin’s research on the Coder and Coder cards, published in 2023, introduces a tangible programming method that eliminates the need for screen-based interaction, making coding accessible to pre-literate children. While still early in their career, Lin’s work has already garnered attention for its practical, inclusive design philosophy, offering a scalable model for introducing programming in early childhood settings. Their research continues to shape how educators and technologists think about the cognitive and developmental trajectory of young programmers.
