Neat! It reminds me of a lot of the tangible programming research from the 2000’s like these:
McNerney, T. S. (2004). From turtles to Tangible Programming Bricks: explorations in physical language design. Personal and Ubiquitous Computing, 8(5), 326–337.
Horn, M. S., & Jacob, R. J. (2007, February). Designing tangible programming languages for classroom use. In Proceedings of the 1st international conference on Tangible and embedded interaction (pp. 159–162). ACM.
Chong, J. W. S., Ong, S. K., Nee, A. Y., & Youcef-Youmi, K. (2009). Robot programming using augmented reality: An interactive method for planning collision-free paths. Robotics and Computer-Integrated Manufacturing, 25(3), 689–701.
It’s nice to see more exploration in AR platforms.
