    摘要: A method for providing information is disclosed. Page descriptors are stored in a server. A printed page is printed by a printer with visible and invisible data. The invisible data is indicative of one or more of the page descriptors. A sensing device senses the invisible data when placed in an operative position relative to the printed page, and transmits information extracted from sensed invisible data to the server. The page descriptor of the printed page is identified by the server, and information associated with the page descriptor and positioning of the sensing device relative to the printed page is provided by the server.

    摘要: An optically imaging pen for interacting with a printed substrate. The pen includes: a nib for interacting with the printed substrate; an image sensor for imaging an area of the printed substrate to provide image data; a processor configured for: (i) identifying target elements in the image data and inferring a perspective transform due to a tilt of the pen; (ii) acquiring and decoding coded data contained in the image data; (iii) calculating a nib position using a tag location, the perspective transform and a known geometry of pen optics; and (iv) generating digital ink based on the nib position.
