摘要
A physical medium is encoded with machine readable information that provides a human interface to a computer system. The information encoded into the medium indicates a computer implemented process, and is encoded according to a spectral encoding scheme, such as encoding by modifying color values of a graphic or other image printed on the medium. For example, a digital watermark or other steganographic data hidden in the image indicates a web page. In response to the user selecting the encoded information area, the machine readable information is decoded, and used to invoke a computer implemented process.
