Invisible tagging system enhances 3D object tracking
Brief
Stop me if you’ve seen this before: a black and white pixelated square in lieu of a physical menu at a restaurant.
QR codes are seemingly ubiquitous in everyday life. Whether you see one on a coupon at the grocery store, a flyer on a bulletin board, or the wall at a museum exhibit, each code contains embedded data.
Unfortunately, QR codes in physical spaces are sometimes replaced or tampered with to trick you into giving away your data to unwanted parties — a seemingly harmless set of pixels could lead you to dangerous links and viruses.
Researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed another potential option: BrightMarker, an invisible, fluorescent tag hidden in 3D-printed objects, such as a ball, container, gadget case, or gear.
