Abstract

A system for enabling a user to access information, said system comprising: a printed substrate, said substrate comprising user information and coded data indicative of a region identity associated with the substrate and of a plurality of locations on the substrate; and a sensing device comprising: an optical sensor for sensing at least some of the coded data when the sensing device is operatively positioned or moved relative to the substrate; a mode selector for allowing the user to select a mode of operation; a processor for generating mode data using the selected mode and interaction data using the sensed coded data, said mode data being indicative of the selected mode, said interaction data being indicative of the region identity and at least one position of the sensing device relative to the substrate; and means for communicating the mode data and the interaction data to a computer system, wherein the mode data together with the interaction data determine a response in the computer system.

Claims

3-1. The system of claim 1, wherein the sensing device is operable in two or more modes selected from the group comprising:

a hyperlinking mode;

a searching mode;

a content-extraction mode;

a mouse mode; and

a handwriting mode.

11. A sensing device for use in cooperation with a printed substrate, said substrate comprising user information and coded data indicative of a region identity associated with the substrate and of a plurality of locations on the substrate, said sensing device comprising:

an optical sensor for sensing at least some of the coded data when the sensing device is operatively positioned or moved relative to the substrate;

a mode selector for allowing the user to select a mode of operation;

a processor for generating mode data using the selected mode and interaction data using the sensed coded data, said mode data being indicative of the selected mode, said interaction data being indicative of the region identity and at least one position of the sensing device relative to the substrate; and

means for communicating the mode data and interaction data to a computer system, wherein the mode data together with the interaction data determine a response in the computer system.

12. The sensing device of claim 11, wherein the mode selector comprises one or more buttons.

13. The sensing device of claim 11, wherein the sensing device is operable in two or more modes selected from the group comprising:

a hyperlinking mode;

a searching mode;

a content-extraction mode;

a mouse mode; and

a handwriting mode.

14. The sensing device of claim 13, wherein the hyperlinking mode instructs the computer system to send a hyperlink URI or a corresponding hyperlinked resource to a user, provided that the sensing device is positioned within a zone of a hyperlink on the printed substrate.

15. The sensing device of claim 13, wherein the searching mode instructs the computer system to:

generate a query expression comprising one or more search terms, at least one of said search terms being identified using a page description corresponding to the printed substrate and the at least one position of the sensing device;

form a request using the query expression; and

send the request, or a results resource including search results obtained using the request, to a user.

16. The sensing device of claim 13, wherein the content-extraction mode instructs the computer system to extract content from a page description corresponding to the printed substrate.

17. The sensing device of claim 13, wherein the handwriting mode instructs the computer system to associate said at least one position, as digital ink, with a corresponding part of a page description corresponding to the printed substrate.

18. The sensing device of claim 13, wherein the mouse mode instructs the computer system to interpret said at least one position as a cursor position in a graphical user interface.

19. The method of claim 15, wherein at least one of said search terms identifies a concept, a person, an organization, a place, a product, a publication, a weather condition, a geographic location, a date, a time of day, a day of the week, a current user location, a user home location, a user demographic indicator, a user preference, a search history, a click-through history, a user interest or a user language.

20. The sensing device of claim 11, wherein the substrate is selected from the group comprising:

a printed document, a printed form, a page of a printed publication, a package for a product item, a label for a product item and a surface of a product item.
