Abstract: A portable device having scanning, imaging or other data-capture capability is described. In some cases, the portable device can indicate to the user when enough information has been captured to uniquely identify a source document. In some cases, the portable device calculates timestamps and location-stamps indicating when and where a data capture occurred. In some cases, the portable device is controlled by gestures. In some cases, the portable scanning device has associated billing and content/service subscription information.

Abstract: Character recognition is described. In one embodiment, it may use matched sequences rather than character shape to determine a computer-legible result.

Abstract: A system for processing a text capture operation is described. The system receives text captured from a rendered document in the text capture operation. The system also receives supplemental information distinct from the captured text. The system determines an action to perform in response to the text capture operation based upon both the captured text and the supplemental information.

Abstract: A system, apparatus and method for filling forms, including using a graphical capture device, are described herein.

Abstract: A facility for initiating a purchase is described. The facility receives a text sequence captured by a user from a rendered document using a handheld text capture device. The facility identifies in the received text sequence a reference to a distinguished product. In response to identifying the reference, the facility presents to the user an opportunity to place an order for the established product. If the user accepts the presented opportunity to order the distinct product, the facility orders the distinct product on behalf of the user.

Abstract: A system for processing text captured from rendered documents is described. The system receives a sequence of one or more words optically or acoustically captured from a rendered document by a user. The system identifies among words of the sequence a word with which an action has been associated. The system then performs the associated action with respect to the user.

Abstract: Systems and methods for quickly and easily getting information about, or included in, a paper document into a public or private digital page. One embodiment of an example system includes a scanner that generates scan information from at least a portion of a paper document and a processing system that receives the generated scan information from the scanner, accesses a database of digital documents, searches the database based on the received scan information, locates a digital document corresponding to the paper document, and sends either the digital content or a hyperlink to the digital content to a predetermined web page.

Abstract: There is provided a screen multiplexor for processing graphical display data and an associated distribution method. A plurality of graphical display data streams is received at the multiplexor, processed and directed to one or more network-connected display devices. The network is a general purpose data network and may be wireless. The directed data streams can be spatially multiplexed, temporally multiplexed, and/or multiplexed in such a way that data from one stream is overlaid on data from another stream. The distribution method and screen multiplexor thus allow a flexible relationship between the number of screens and the sources of the information to be displayed thereon.

Abstract: A display device for transmitting, over a general purpose data network, graphical data to a remote device, the display device comprising a framebuffer memory for storing the graphical data; and a network interface for maintaining two-way network transmission of graphical data to and from the display device and operable to read or write to the framebuffer memory; wherein the network interface transmits the contents of the framebuffer memory to at least one remote device over the network.

Abstract: Systems and methods are provided having a plurality of ultra-thin client devices coupled to at least one display device and a data processing device coupled to the ultra-thin client devices over a general purpose data network, the data processing device being operable to transmit image data directly representing at least a portion of the image displayed on one or more of the display devices over the general purpose data network.

Abstract: An interactive desktop system comprising a work surface, a display device such as a projector for displaying images in a first area on the work surface, a camera for capturing images in a second area on the work surface, and an image processor, coupled to the display device and to the camera, said image processor being suitably programmed (a) for causing the display of barcodes on the work surface, (b) for causing the capture of said barcodes and, in dependence on the captured information, (c) for determining the position of said second area relative to said first area. The barcodes are displayed in a horizontal then vertical orientation, with an image capture in each display orientation being performed by the camera. This enables the camera's field of view within the displayed image to be determined. In an alternative embodiment, glyph codes may be used instead of barcodes.
