The CyberCode is a visual tagging system based on a 2Dbarcode technology and provides several features not provided by other tagging systems. 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. This paper describes examples of augmented reality applications based on CyberCode, and discusses some key characteristics of tagging technologies that must be taken into account when designing augmented reality environments.

In this paper we introduced CyberCode, a visual tagging system designed for augmented reality, by describing a series of examples. Some of these applications have been “commercialized” as a bundled software tool on Sony notebook PC with a built-in camera. We think that CyberCode is an affordable and flexible technology that can be used to construct a wide variety of augmented reality systems. Even when some other tagging technology is more suitable for a particular application, CyberCode often works as a good "first approximation" and helps system designers to prototype their ideas quickly.
