    摘要: A method of interacting with a printed form. The method includes the steps of: maintaining a page description corresponding to a printed form; receiving, indicating data from an optically imaging pen operated by the user, the indicating data being indicative of the identity of the form and of a position of a nib of the pen relative to the form; retrieving the page description using the identity of the form; and identifying an interaction with the form using the position of the nib and the retrieved page description. The position of the nib is determined by inferring a perspective transform from perspective-distorted corners of a tag of known size when sensing the coded data and using the perspective transform together with a known geometry of pen optics to compute the position of the nib.

    摘要: A system for enabling competition entry is provided using a printed product label provided on a product item. The system has a sensing device, computer system and display device. The sensing device senses coded data from the label attached to the product item and generates interaction data representing interaction of the sensing device with the coded data. The coded data is uniquely indicative of the product item and the label has regions including information fields, buttons and/or entry fields. The computer system receives the interaction data and correlates the interaction data with a competition. Interaction with at least one of the buttons using the sensing device causes the computer system to display information on the display device.

    摘要: An input arrangement for controlling an electronic device. The arrangement comprises a substrate have a position-coding pattern printed thereon. The position-coding pattern codes first and second sets of absolute positions on spatially separate areas of the substrate. The first and second sets of absolute positions are mutually exclusive and coded by first and second subsets of the position-coding pattern. A handheld image-recording device comprises an image sensor for recording images of the position-coding pattern a processor is configured for deriving an absolute position from the position-coding pattern in the recorded image and providing an instruction to the electronic device to perform a first function when the absolute position belongs to the first set and a second function when the absolute position belongs to the second set.
