Abstract:
A method of gaining access to goods or services includes the steps of: writing a signature within a verification zone of an encoded base using an optically imaging pen having a marking nib; optically reading a sequence of absolute locations corresponding to the signature from the encoded base; and checking if the locations are within a region registered as belonging to an authorized user. Access to the goods or services is granted if the location is within the region belonging to the authorized user and the sequence of locations corresponds to a previously registered signature of the authorized user, otherwise access is denied.
Abstract:
A system for enabling user interaction with computer software. The system includes a sensing device and a computer system. The computer system generates print data and transfers it to a printer. The printer prints a form by printing information related to an interactive element and coded data indicative of the interactive element in response to the print data. The sensing device has an image sensor for capturing images of the coded data, which is coincident with the information, and a processor for identifying the coded data from the captured images, determine an orientation and position of the coded data, decode the coded data, and generate indicating data using the determined information. The indicating data, which is indicative of the interactive element is used by the computer system to identify the interactive element and perform a corresponding action.
Abstract:
A method of retrieving an image using a print medium is disclosed. The method starts by sensing the print medium using a sensor module of a mobile telecommunications device to obtain data encoded on a surface of the print medium. The data encodes at least a print media identifier. From the data the print media identifier is determined. The image is associated with the print media identifier. The image is retrieved by the mobile telecommunications device, and displayed on a display of the mobile telecommunications device.
Abstract:
The present invention provides methods and systems related to arranging objects (e.g., circles, dots and other shapes) in images and graphics to convey a machine-readable signal. One claim recites a method including: integrating a plurality of objects in an image or graphic, the objects being arranged in a pattern that is machine-readable by a programmed computer processor, the plurality of objects being integrated in the image or graphic so that the pattern is hidden in the image or graphic through cooperation with design elements of the image or graphic; and providing a visible structure for aiding in machine-reading of the pattern by the programmed computer processor. Of course, other combinations are provided and claimed as well.
Abstract:
An electronic pen for interacting with a substrate having coded data disposed thereon. The pen includes: 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; and a processor configured to generate indicating data indicative of the interaction with the substrate. 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.
Abstract:
A data set is transformed to a domain in which values are robust to distortion. The values are then expanded to carry auxiliary data. To recover the data, the data set is transformed into the domain, further transformed to get a set of possibly expanded data, and then processed to extract auxiliary data from the expanded values.
Abstract:
The present invention relates to a method for providing a content stream (5) comprising processing information, comprising the steps of providing (S1) content data (3) comprising image and/or audio data, acquiring (S3) auxiliary data (4) from the content data (3) representing information for processing the content data (3) and embedding (S8) the auxiliary data (4) into the content data (3) thereby providing said content stream (5).The present invention further relates to such a content stream (5) and to a device for providing such a content stream (5).Additionally, the present invention relates to a method and a device for processing a content stream (5) comprising processing information.
Abstract:
A pen system for recording a track of handwritten information created by a handheld electronic pen. The pen system includes the handheld electronic pen and a second memory unit located in an external data storage device. The electronic pen has an image sensor for optically imaging a position-coding pattern printed on a surface, a processor for recording the handwritten information as digital ink and a first memory unit for storing the digital ink. The first and second memory units are connected in such a way that a transmission of digital ink is caused to occur automatically from the first memory unit to the second memory unit. Receipt of the digital ink by the second memory unit causes the second memory unit to associate the track of handwritten information with a stored description of the surface.
Abstract:
A printer for printing an interface is provided. The printer has a coded tag generator configured to generate coded tags based on identity data indicative of an identity associated with the interface and position data defining a relative position of each tag on the interface, and a printhead for printing the interface with the coded tags at the positions defined by the position data and having the identity data.
Abstract:
The present invention relates generally to controlling rendering of video to particular audiences, e.g., children. For example, one claim recites a method including: obtaining video or image data, the video or image data comprising information steganographically hidden in data representing perceptual portions of the video or image data; analyzing the video or image data to obtain the hidden information, the information comprising data associated with suitability for viewing of the video or image data for a particular demographic; comparing the data to predetermined information; and based at least on said act of comparing, determining whether to render the video or image data for display. Of course, other claims are provided too.
