Abstract

A technique for providing enhanced intuitive navigation in a virtual world. User selectable hot spots are provided within a virtual world that users may select to automatically be moved to predetermined move-to coordinates within the virtual world. The user may be transported directly to the move-to coordinates or the user may have its motion controlled by the virtual world to in essence walk the user to the move-to coordinates within the virtual world. The selectable hot spot may become inactive following selection of the hot spot by a user until the user moves off of the move-to coordinates, or a plurality of move-to coordinates may be provided such that the hot spot remains active until all of the move-to coordinates are occupied by users. Additionally, the hot spot may be visually enhanced to make it easier to be seen and selected when the user is more than a predetermined distance from the hot spot within the virtual world.

Claims

1. Computer readable code for providing enhanced navigation for participants in a virtual world, comprising:

first subprocesses for displaying a selectable hot spot image within a virtual world; and

second subprocesses for logically moving a participant in the virtual world to pre-specified move-to coordinates within the virtual world upon the participant selecting the hot spot image.

2. Computer readable code for providing enhanced navigation according to claim 1, further comprising:

third subprocesses for making the hot spot image unselectable following selection of the hot spot image by the participant until the participant has moved off of the move-to coordinates.

3. Computer readable code for providing enhanced navigation according to claim 1, further comprising:

fourth subprocesses for associating a predetermined number of move-to coordinates with the selectable hot spot image and moving each participant to an unoccupied one of the move-to coordinates upon participant selection of the hot spot image until all of the move-to coordinates are occupied, and then rendering the hot spot image non-selectable.

4. Computer readable code for providing enhanced navigation according to claim 1, further comprising:

fifth subprocesses for providing a visually enhanced hot spot image to the participant when the participant is more than a predetermined distance from the hot spot image within the virtual world.

5. Computer readable code for providing enhanced navigation according to claim 1, further comprising:

sixth subprocesses for associating moving options with the selectable hot spot so that the participant is moved to the move-to coordinates in a predetermined manner upon selection of the hot spot image by the participant.

6. Computer readable code for providing enhanced navigation according to claim 5, wherein the predetermined manner of movement is to instantly transport the participant to the move-to coordinates.

7. In a computing environment, a system for providing enhanced intuitive navigation for users of a virtual world, comprising:

means for displaying a selectable hot spot within the virtual world, wherein the selectable hot spot has a predetermined set of navigation controls associated therewith; and

means for moving a user of the virtual world in accordance with the predetermined set of navigation controls upon selection of the hot spot by the user.

8. A system for providing enhanced intuitive navigation according to claim 7, further comprising:

means for visually enhancing the hot spot for the user when the user occupies a location in the virtual world that meets predetermined enhancement criteria.

9. A system for providing enhanced intuitive navigation according to claim 7, wherein the virtual world is a VRML-based site accessible by users using VRML-enabled browsers via the World Wide Web.

10. A method for providing enhanced navigation for participants in a virtual world, comprising the steps of:

displaying a selectable hot spot image within a virtual world; and

logically moving a participant in the virtual world to pre-specified coordinates within the virtual world upon the participant selecting the hot spot image.

11. A method for providing enhanced navigation according to claim 10, further comprising the step of:

making the hot spot image unselectable following selection of the hot spot image by the participant until the participant has moved off of the pre-specified coordinates.

12. A method for providing enhanced navigation according to claim 10, further comprising the step of:

associating a predetermined number of pre-specified coordinates with the selectable hot spot image and moving each participant to an unoccupied one of the pre-specified coordinates upon participant selection of the hot spot image until all of the pre-specified coordinates are occupied, and then rendering the hot spot image non-selectable.

13. A method for providing enhanced navigation according to claim 10, further comprising the step of:

providing a visually enhanced hot spot image to the participant when the participant is more than a predetermined distance from the hot spot image within the virtual world.

14. A method for providing enhanced navigation according to claim 10, further comprising the step of:

associating moving options with the selectable hot spot so that the participant is moved to the pre-specified coordinates in a predetermined manner upon selection of the hot spot image by the participant.

15. A method for providing enhanced navigation according to claim 10, further comprising the step of:

visually enhancing the selectable hot spot image for the participant when the participant occupies a location in the virtual world that meets predetermined enhancement criteria.
