touchBase: A Tangible Programming Language for Physical Computing
February 2024 - present
Abstract: Tangible programming languages (TPL) involve physical objects, often interlocking blocks, that represent computer programming elements. Users connect TPL blocks in logical chains to construct code that typically controls the behavior of another device. Designed for young children, they offer a playful and embodied approach to computer science education. While these systems can effectively teach basic programming concepts, TPL code lacks transferability and expressivity, which limits the types of problems that learners can engage with. Our work explores how designing for the multimodality of TPLs can support greater complexity in programming concepts, a smoother transition to advanced programming settings, and enhanced learner expression. We present touchBase, a TPL that leverages concepts in physical computing and principles of Gestalt psychology to support a culturally-sustaining approach to CS learning design.
