Abstract

An exploration system is described for assisting the user in navigating within a virtual space that can be represented using a tiled multi-resolution image. The exploration system receives various selection factors that have a bearing on the selection of suggested items from a collection of candidate items. The selection factors can include focus-of-interest information that pertains to a user'"'"'s presumed current focus of interest within the virtual space, semantic association information that describes semantic relationships among different features pertaining to the virtual space, and history information which describes prior expressed interest in items, e.g., as manifested in prior selections of items. The exploration system uses these selection factors to determine a set of suggested items. The suggested items provide recommendations to the user regarding items that may be germane to the user'"'"'s current interests in his or her navigation within the virtual space.

Claims

1. A method, implemented by one or more computing devices, for presenting suggested items, comprising:

receiving selection factors, the selection factors including;

candidate item information that describes characteristics of candidate items, the candidate items being selectable for presentation to a user as the user navigates through a virtual space, the virtual space being represented as a multi-resolution image;

focus-of-interest information that describes a current focus of interest of the user within the virtual space;

semantic association information that describes semantic relationships among features pertaining to the virtual space; and

history information that pertains to prior interest in items;

determining suggested items, selected from among the candidate items, based on one or more of the selection factors;

presenting the suggested items to a user;

receiving a navigation selection from the user in response to said presenting; and

repeating said receiving of the selection factors, said determining, said presenting, and said receiving of the navigation selection at least one time, to thereby define a navigation path through the virtual space in a guided manner.

2. The method of claim 1, wherein the virtual space has at least one spatial dimension.

3. The method of claim 1, wherein the virtual space has at least one temporal dimension.

4. The method of claim 1, wherein the virtual space represents a plurality of categories of items.

5. The method of claim 1, wherein the multi-resolution image is a tiled multi-resolution image having plural image components.

6. The method of claim 1, wherein the focus-of-interest information includes zoom level information that describes a current zoom level within the virtual space.

7. The method of claim 1, wherein the focus-of-interest information includes field-of-view information that describes a portion of the virtual space that the user is presumed to be interested in at a current time.

8. The method of claim 7, further comprising assessing the field-of-view information based on movement by the user of a cursor within the virtual space.

9. The method of claim 1, wherein the semantic association information relates two candidate items based on an assessment of semantic similarity between the two candidate items.

10. The method of claim 1, wherein the history information includes personal history information that describes prior navigation selections made by the user over plural navigation sessions.

11. The method of claim 1, wherein the history information includes current navigation information that describes prior navigation selections made by the user in a current navigation session.

12. The method of claim 1, wherein the history information includes group navigation information that describes navigation selections made by a group of users.

13. The method of claim 1, wherein the suggested items include at least one object within the virtual space as represented by an image component of the multi-resolution image.

14. The method of claim 1, wherein the suggested items include at least one narrative that provides a tutorial pertaining to the virtual space.

15. The method of claim 14, wherein said at least one narrative is linked to at least one object within the virtual space.

16. The method of claim 1, wherein the suggested items include at least one information item that provides supplemental information regarding an object within the virtual space.

17. An exploration system, implemented by one or more computing devices, for presenting suggested items in a course of navigation within a virtual space by a user, comprising:

a suggested item decision module configured to receive selection factors, the selection factors including;

candidate item information that describes characteristics of candidate items, the candidate items being selectable for presentation to the user as the user navigates through the virtual space, the virtual space being represented as a multi-resolution image having plural image components;

focus-of-interest information that describes a current focus of interest of the user within the virtual space;

semantic association information that describes semantic relationships among features associated with the virtual space; and

history information that pertains to prior interest in items;

the suggested item decision module also being configured to determine suggested items, selected from among the candidate items, based on the candidate item information, the focus-of-interest information, the semantic association information, and the history information; and

a presentation module configured to present the suggested items to the user.

18. The exploration system of claim 17, wherein the presentation module is configured to present the suggested items as annotations which accompany a representation of the virtual space.

19. The exploration system of claim 17, wherein the virtual space has at least one spatial dimension and at least one temporal dimension.

20. A computer readable medium for storing computer readable instructions, the computer readable instructions providing an exploration system when executed by one or more processing devices, the computer readable instructions comprising:

logic configured to receive selection factors, the selection factors including;

candidate item information that describes characteristics of candidate items, the candidate items being selectable for presentation to a user as the user navigates through a virtual space;

zoom level information that describes a current zoom level within the virtual space;

focus-of-view information that describes a portion of the virtual space that the user is presumed to be interested in at a current time;

semantic association information that describes semantic relationships among features associated with the virtual space;

personal history information that describes prior navigation selections made by the user in a current navigation session and over prior navigation sessions; and

group navigation information that describes navigation selections made by a group of users; and

logic configured to determine suggested items, from among the candidate items, based on one or more of the selection factors, the suggested items selected from among;

objects within the virtual space;

narratives that provide tutorials pertaining to the virtual space, the narratives having links to objects associated with the narratives; and

information items that provide supplemental information regarding objects within the virtual space.
