Abstract
A print (e.g., on paper) user interface (PUI) device for decoding an embedded message to activate a function is described. The PUI can be used for transforming an embedded message into cognizable human sensory inputs. The device includes a reader and a processor. The reader can sense light from a pattern of pixels on a printed surface and determines the pixel values of the pixels. The pattern of pixels constitutes a foreground visual image that conveys cognizable information to an observer. The primary function of the embedded message need not be to launch a Web-site but to display more information related to the cognizable information. The processor has a program of computer codes readable by the processor to recover embedded message from the pattern of pixels, the program includes codes for determining the embedded message by determining binary values based on the pixel values for pixels from the pattern of pixels and codes for performing a function according to the embedded message to result in resultant information displayable by a display suitable for human sensory reception.
