    摘要: A mouse incorporating a camera captures an image of embedded data from a substrate under the mouse. The embedded data in the image is decoded to determine address or location information coded in the embedded data. Based on the decoded information and other user input signals, such as mouse button selection signals, the computer executes operations. The mouse also has a display controlled by the computer for providing visual feedback to a user. The display might generate an image of the substrate area under the mouse, making it appear to the user as if they are looking through the mouse directly onto the substrate. The display may also generate visual feedback regarding operations occurring in the computer, such as selection or other computer operations.

    摘要: A user interface is implemented using visual indicia and a background for the visual indicia that encodes address information. The background appears visually as a stipple pattern, but is implemented using glyphs which form an address carpet that encodes address information uniquely identifying each location of the user interface. An image capture device is used to capture an area of the address carpet that is at or near visual indicia of interest to the user while selecting a location in the visual indicia. The image capture device captures the area of interest, and transmits the image area to a computer for processing. The computer first determines the proper orientation of the image, and then decodes the information encoded by the glyphs. The decoding results in an X, Y address identifying the location of the captured area in the address carpet and, by reference, the address of the selected location. Based on the address, the computer may perform an operation associated with the area.

    摘要: A camera pen is made from a pen-like housing contains a camera and has a button for sending a signal to a computer which directs the camera to capture an image. The pen-like housing includes landing gear on one end. The landing gear has an opening which forms a flat surface that is angled such that when a user places the camera pen on a surface, the angle at which the pen rests on the surface is ergonomically comfortable for the user. Furthermore, the camera is oriented toward the opening so that when the user presses the button indicating a desire to capture an image, the camera captures the image in the opening. By combining a camera with a pen-like device, the user can comfortably capture image information from a surface.

    摘要: A viewport lens displays registered information registered using embedded data. An image capture device captures an image from the substrate that includes embedded data. The embedded data in the captured image is decoded to create information regarding the substrate, such as location, orientation, or a label. Based on the information regarding the substrate, information is generated that is registered with the substrate. In one embodiment, the information is registered with the substrate by optically combining the generated information with substrate information in a viewport lens.

    摘要: A captured image includes a portion of a set of two-dimensional address codes. The portion of address codes can be decoded to determine a discrete pointer uniquely defining the portion. The captured image is first processed to determine the orientation of the portion, and then decoded based on the orientation to determine the discrete pointer. To determine the orientation of the portion, the portion is first analyzed to determine values at discrete locations within the portion. The values at each location form a matrix of binary data. The values of the matrix are then correlated to determine an orientation of the captured portion of two dimensional address codes. After determining the orientation of the portion, the values can be further analyzed to determine a discrete pointer that identifies the location of the portion within the address space defined by the two-dimensional address codes.

    摘要: A self-clocking glyph code is provided for encoding n-bit long digital values (where n>1) in a logically ordered sequence of composite glyphs that are written, printed, or otherwise recorded on a hardcopy recording medium in accordance with a predetermined spatial formatting rule. As used herein, a "composite glyph" is a graphical symbol that has a plurality of predefined, substantially orthogonal, graphical characteristics; each of which is capable of assuming any one of a plurality of predefined graphical states. An n-bit long digital value is distributively encoded in a glyph of this type by decomposing its n-bits, prior to or during the encoding, into a plurality of shorter, ordered, non-overlapping bit strings. The digital values of these bit strings, in turn, are encoded in the states of respective graphical characteristics of the composite glyph in a predetermined logical order, thereby preserving the logical ordering of the bit strings.
