Abstract

Space-time trails are annotated automatically and/or manually with meaningful information. Mechanisms are provided for receipt of implicit and/or passive data (e.g., provided by sensors) as well as explicit and/or active data (e.g., provided by users). Extraction techniques are provided to either or both types of data to produce useful information to annotate or otherwise interpret data associated with a space-time trail. Persisted annotated trails can subsequently be employed to glean valuable information. Furthermore, goal-directed recommendations can be generated with respect to annotated trails, among other things.

Claims

1. A space-time trail annotation system, comprising:

a receiver component that receives sensor data; and

an annotation component that automatically annotates a space-time trail with information derived from the sensor data.

2. The system of claim 1, further comprising a mining component that employs one or more data mining algorithms over the sensor and/or other stored data to extract the annotation information.

3. The system of claim 1, further comprising a capture component that captures and provides sensor data to the receiver component.

4. The system of claim 3, the capture component forms part of a mobile device including at least one of a mobile phone, personal digital assistant and media player.

5. The system of claim 1, further comprising an interface component that facilitates active route annotation by a user.

6. The system of claim 1, further comprises a recommendation component that employs one or more collaborative filters and/or matching techniques to generate one or more trail recommendations.

7. The system of claim 6, the recommendation component generates one or more goal-directed trail recommendations.

8. The system of claim 1, further comprising an interface component that renders annotated paths.

9. The system of claim 1, further comprising a context component that supplies context information to the annotation component for use in route annotation.

10. The system of claim 1, the space-time trail is a digital trace.

19. The method of claim 1, further comprising generating route recommendations based on user performance goals and/or user profile.

20. The method of claim 19, further comprising generating route recommendations based on context information associated with the user, location and/or third-party events.

11. A system that facilitates route annotation, comprising:

means for receiving data associated with user state and location; and

means for automatically annotating a route with information derived from the data.

12. The system of claim 11, further comprising a means for affording at least one goal-directed recommendation based on route annotation.

13. A method for annotating physical routes, comprising:

receiving sensor data indicative of user state, environmental state and geographical location;

extracting meaningful information from the data; and

annotating a route automatically with the extracted information.

14. The method of claim 13 extracting meaningful information, comprising executing of one more data mining algorithms.

15. The method of claim 14, further comprising executing one or more of an algorithm that extracts a person'"'"'s pace, road surface smoothness and/or cycling cadence from raw acceleration data.

16. The method of claim 14, further comprising executing an algorithm that extracts a person'"'"'s heart rate from raw ECG data.

17. The method of claim 14, further comprising persisting annotated routes to a network accessible database.

18. The method of claim 17, further comprising displaying the annotated routes to users in accordance with associated permissions.
