![]() ![]() By adding a layer of connectivity between data and physical objects, users would have access to a more interactive experience with the world around them. This makes them tamper-proof while seamlessly embedding metadata into the physical world. Surrounding objects could be obscured from view using a longpass filter, another attachable piece that would only spot the fluorescence.īrightMarkers are imperceptible to the naked eye-and unobtrusive, meaning they don't alter an object's shape, appearance, or function. The researchers designed two attachable hardware setups capable of detecting BrightMarkers: one for smartphones and one for augmented reality (AR) and virtual reality (VR) headsets.īoth have the capacity to view and scan the markers, which resemble glow-in-the-dark QR codes. The fluorescent materials enable each tag to emit light at a specific near-infrared wavelength, making them viewable with high contrast in infrared cameras. Users will need to embed their markers into an object before it's fabricated, meaning the tags cannot be added to existing items. With fluorescent filaments inserted into the printer, users can fabricate an object with a hidden tag, much like an invisible QR code. After placing the tag within the geometry of their design, they can export it as an STL file for 3D printing. To create a BrightMarker, users can download the CSAIL team's software plugin for 3D modeling programs like Blender. The researchers believe their system can enhance motion tracking, virtual reality, and object detection. 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. 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. 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. QR codes are seemingly ubiquitous in everyday life.
