C-Band: A Flexible Ring Tag System For Camera-Based User Interface

This paper proposed a new visual tag system for enhancing real-world media interaction using handheld camera devices. This paper also described performance evaluations of the prototype, and its applications. C-Band is based on a ring with a color pattern code. A C-Band tag can provide a self-contained URL, and is flexible enough to allow various aesthetic designs for the tag's surface. Furthermore, the tag's structure is useful for building interactive techniques. Taken together, these features suggest that C-Band is an effective method to build various attractive camera-based media interactions.
