CyberCode
CyberCode is a visual tagging system based on a 2D barcode technology. CyberCode tags can be recognized by the low-cost CMOS or CCD cameras found in more and more mobile devices, and it can also be used to determine the 3D position of the tagged object as well as its ID number.[1]
A CyberCode tag is a 2D barcode symbology. A computer with attached camera can locate the tag and decode the data within the 2D barcode. Visual markers surrounding the barcode allow the computer to quickly locate the tag within the field of view of the camera. Additionally, the design of the CyberCode tag allows the computer to track both the tag's 3D position and orientation. The design of the CyberCode tag allows it to be read by low-cost CMOS and CCD cameras found in many mobile devices.[1]
The ability for a camera to quickly acquire and track a CyberCode tag as well as its ability to be used with many of the cameras already in use by consumers has led to its use in augmented reality. CyberCode tags affixed to real-world objects would allow the user to view the world around them through the camera and have the computer overlay additional information over the display. The information encoded in the barcode identifies the object, and because of the tag's design, the computer can detect the orientation of the object relative to the viewer.
