DynaTags: Low-Cost Fiducial Marker Mechanisms

Published at ICMI 2022.

Printed fiducial markers are inexpensive, easy to deploy, robust and deservedly popular. However, their data payload is also static, unable to express any state beyond being present. For this reason, more complex electronic tagging technologies exist, which can sense and change state, but either require special equipment to read or are orders of magnitude more expensive than printed markers. In this work, we explore an approach between these two extremes: one that retains the simple, low-cost nature of printed markers, yet has some of the expressive capabilities of dynamic tags. Our “DynaTags” are simple mechanisms constructed from paper that express multiple payloads, allowing practitioners and researchers to create new and compelling physical-digital experiences.

How is this not more popular

I really like the examples where they are used for the assembly of the covid test and furniture, it would give an extra bit of confidence that you're using it correctly.

Ikea furniture: Confirm with instructions
DynaTag furniture: N I C E ✔

Kinda like that video game called Witness.
If you need a human to switch states, you can just print out multiple QR codes (Feducuial marker) and velcro it on the surface you need to. Movable parts will wear out unless you make them of plastic.

I do think it could be interesting.

This is the exact sort of useless non-solution to a non-problem I'd expect from someone calling QR codes "fiducial markers" to try to sound like they've done something special.
