  • Publication number: 20130176221
    Abstract: An optical sensing device for controlling a computer system is disclosed. The device has a nib for receiving a nib force upon the nib being pressed against a substrate and a nib switch coupled to the nib. An optical sensor images optically coded data printed on the substrate. A processor effects a mode change between a cursor control mode and a hyperlinking mode upon the nib force actuating the nib switch, generates cursor control data when the optical sensing device is in the cursor control mode, and generates interaction data when the optical sensing device is in the hyperlinking mode. The interaction data indicates a coordinate position of the optical sensing device relative to the substrate. The cursor control data or the interaction data is then communicated to the computer system, where the cursor control data initiates a cursor control response and the interaction data initiates a hyperlinking response.

  • Patent number: 8424774
    Abstract: A process for decoding coded data is provided. The coded data has a plurality of layouts which each have order n (at least two) rotational symmetry and encode a codeword of a sequence of n symbols distributed at n locations about a center of rotational symmetry of the respective layout such that decoding the symbols at each of the n orientations of the layout produces n representations of the codeword. Each representation is a different cyclic shift of the codeword and is indicative of the degree of rotation of the layout. The process involves, at the computer system, identifying a layout from an image including the coded data, decoding the identified layout to determine a codeword representation, and determining a degree of rotation of the layout from the determined representation.
