摘要:
A method of using a sensing device to read coded data is provided. The coded data is arranged in accordance with a layout having mirror and n-fold rotational symmetry about a center of rotation, where n is at least two. The layout includes n identical first sub-layouts rotated 1/n revolutions apart about the center of rotation, and n identical second sub-layouts rotated 1/n revolutions apart about the center of rotation. Each second sub-layout is a reflection of a corresponding one of the first sub-layouts. At least one sub-layout includes rotation-indicating data that distinguishes that sub-layout from at least one other sub-layout and reflection-indicating data that distinguishes the reflections of reflected sub-layouts. The method includes sensing a layout using the sensing device, decoding the coded data of the sensed sub-layouts, thereby determining the rotation-indicating data of that sub-layout, and using the rotation-indicating data to interpret the meaning of the coded data.

An electronic pen for interacting with a substrate having coded data disposed thereon. The pen comprises: an image sensor for sensing the coded data when the pen is used to interact with the surface; a cartridge having a nib for contacting the surface; a retraction mechanism for slidably moving the cartridge between a retracted position and an extended position; a force sensor cooperating with the retraction mechanism; a processor configured to generate indicating data indicative of the interaction with the substrate; and communication means for communicating the indicating data to a computer system. The image sensor is configured to sense the coded data only when the force sensor detects that the nib is in contact with the substrate.

A system for enabling user interaction with computer software which includes a computer system which transfers print data to a printer which is responsive to the print data to print a form by printing information indicative of a text field coincident with coded data at least partially indicative of the text field, so that when a sensing device is moved in an operative position relative to the text field, the sensing device can sense the coincident coded data and generate the indicating data indicative of movement of the sensing device relative to the text field. The computer system uses the indicating data to determine the movement and then perform an action associated with the text field based on the movement. The computer system determines a handwritten signature using the movement and a predetermined signature using a user identity, and verifies the user by comparing the handwritten and predetermined signatures.

A method of printing a dithered image is provided which includes retrieving a planarized linear image from a memory, interpolating, with a processor, the resolution of said retrieved planarized linear image to an intermediate resolution in dependence of the color planes of said retrieved planarized linear image, interpolating, with the processor, the intermediate resolution to a print resolution, producing, with the processor, a dithered image in real-time from said interpolated image at the print resolution, and printing the dithered image using a printhead.

A method is describe in which an orientation indicator on a print medium inserted into a printer is sensed, the orientation indicator identifying the orientation of content previously printed on the print medium, the orientation of the content previously printed on the print medium is determined, and print data is rotated prior to printing the print data onto the print medium by the printer to take into account the orientation of the content previously printed on the print medium.

A method for authenticating a pharmaceutical product, the pharmaceutical product being associated with packaging having disposed thereon or therein coded data including a number of coded data portions, each coded data portion being indicative of an identity of the pharmaceutical product and at least part of a digital signature of at least part of the identity. The method includes having a computer system receive indicating data from a sensing device, the sensing device being responsive to sensing of the coded data to generate indicating data at least partially indicative of the identity of the pharmaceutical product and the signature part. The computer system determines the identity at least one determined signature part and uses these to authenticate the pharmaceutical product.

A method of retrieving a document from a database of hierarchical electronic document versions is disclosed. Each document version is associated with a unique document instance. In the method a search form is printed. The search form includes a search instruction input field relating to at least one parameter of a search to be carried out within the database and a plurality of coded data tags. Each coded data tag encodes a location of that coded data tag on the search form. The coded data tags are sensed by a sensing device as the sensing device is used to handwrite at least one search term on the search form. Data representing the parameter and the at least one search term is generated, with the data representing the at least one search term being generated from the locations of the coded data tags. Next, a search is carried out within the database based on the at least one search term and parameter in order to identify document versions. A results form is printed, with the results form containing data representing the document versions identified in the search and coded data tags. By sensing one or more coded data tags on the results form, the document version associated with the coded data tag sensed on the results form is retrieved and printed.
