MIT Researchers Develop InfraredTags That Let You Embed Invisible Markers in Augmented Reality – TechEBlog
MIT researchers have developed InfraredTags, or 2D markers and barcodes that cannot be seen with the naked eye, but are able to be 3D printed as part of objects. These invisible markers can be detected rapidly by low-cost near-infrared cameras. This is achieved by printing objects from an infrared-transmitting filament, which infrared cameras can see through, and by having air gaps inside for the tag’s bits.

The researchers then designed a user interface that facilitates the integration of common tags (QR codes, ArUco markers) with the object geometry to make them 3D
