Existing approaches for embedding unobtrusive tags inside 3D objects require either complex fabrication or high-cost imaging equipment. We present InfraredTags, which are 2D markers and barcodes imperceptible to the naked eye that can be 3D printed as part of objects, and detected rapidly by low-cost near-infrared cameras. We achieve this 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, which… 
Demonstrating InfraredTags: Decoding Invisible 3D Printed Tags with Convolutional Neural Networks
TLDR
A user interface is built that facilitates the integration of common tags (QR codes, ArUco markers) with the object geometry to make them 3D printable as InfraredTags, which are invisible 2D markers and barcodes that are 3D printed as part of objects.
Fabricate It or Render It? Digital Fabrication vs. Virtual Reality for Creating Objects Instantly
TLDR
This panel will discuss the pros and cons of both approaches to digital fabrication, discuss which one may prevail in the future, and what opportunities exist for closer collaboration between researchers from the two research fields.

Embedding Information in 3D Printed Objects with Curved Surfaces Using Near Infrared Fluorescent Dye
TLDR
The experimental results show that the authors can hide a barcode inside an object so that no one can see it from the outside and that the information expressed by the barcodes inside the objects can be nondestructively read out.
LayerCode: optical barcodes for 3D printed shapes
TLDR
It is shown that LayerCode tags can work on complex, nontrivial shapes, on which all previous tagging mechanisms may fail, and an encoding algorithm is introduced that enables the 3D printing layers to carry information without altering the object geometry.
CapCodes: Capacitive 3D Printable Identification and On-screen Tracking for Tangible Interaction
TLDR
A novel approach using a coding scheme for the automatic identification of tangibles by touch inputs when they are touched and shifted is presented and showed that the CapCodes can be integrated into existing 3D models and the approach could also be applied to untouched use for larger tangibles.
G-ID: Identifying 3D Prints Using Slicing Parameters
TLDR
G-ID is a method that utilizes the subtle patterns left by the 3D printing process to distinguish and identify objects that otherwise look similar to the human eye by varying slicing parameters that do not change the model geometry but can be detected as machine-readable differences in the print.

Seedmarkers: Embeddable Markers for Physical Objects
TLDR
Seedmarkers, shape-independent topological markers that can be embedded in physical objects manufactured with common rapid-prototyping techniques are presented and a generation algorithm making use of weighted Voronoi diagrams for topological optimization is introduced.
Projection-based visualization of tangential deformation of nonrigid surface by deformation estimation using infrared texture
TLDR
A computer vision technique that estimates the tangential deformation of a nonrigid surface by measuring the frame-by-frame movement of an IR texture on the surface, which is flexible for multiple deformable materials, such as viscoelastic and elastic materials.
DeepFormableTag: end-to-end generation and recognition of deformable fiducial markers
TLDR
This paper presents the captured results of 3D scanning using a 2D array of multiple fiducial markers as structured light patterns as well as motion tracking of human body motion using the authors' deformable markers.
CapacitiveMarker: novel interaction method using visual marker integrated with conductive pattern
TLDR
This study proposes a novel visual marker, "CapacitiveMarker", which can be recognized both by a camera and capacitive display, and proposes a new interaction method using Capacitive Marker through applications.
TUIC: enabling tangible interaction on capacitive multi-touch displays
TLDR
TUIC simulates finger touches on capacitive displays using passive materials and active modulation circuits embedded inside tangible objects, and can be used with multi-touch gestures simultaneously.
