Abstract

The gesture-based searching of a line pattern representation amongst a collection of line pattern representations. Upon detecting an input gesture, a computing system matches the input gesture against each of multiple pattern representations. Each line pattern representation represents a line pattern having a changing value in a first dimension as a function of a value in a second dimension. At least some of the matched set may then be visualized to the user. The input gesture may be a literal line pattern to match against, or might be a gesture that has semantic meaning that describes search parameters of a line pattern to search for. The matched set may be presented so that a display parameter conveys a closeness of the match.

Claims

1. A method for searching a line pattern representation amongst a collection of line pattern representations, the method comprising:

an act of detecting an input gesture input by a user into a computing system;

an act of automatically matching the input gesture against each of a plurality of line pattern representations, reach representing a line pattern having a changing value in a first dimension as a function of a value in a second dimension; and

an act of visualizing at least one line pattern representation of the matched set on a display of the computing system.

2. The method in accordance with claim 1, wherein the input gesture is an input line pattern, wherein the act of automatically matching the input gesture comprises an act of automatically searching one or more line pattern representations that have line patterns that most closely match the input line pattern.

3. The method in accordance with claim 1, wherein the input gesture has semantic meaning regarding search parameters.

4. The method in accordance with claim 3, wherein the search parameters correlate to a rate of change of a line pattern to search for.

5. The method in accordance with claim 3, wherein the search parameters correlate to a direction of change of a line pattern to search for.

6. The method in accordance with claim 3, wherein the search parameters correlate to a volatility of a line pattern to search for.

7. The method in accordance with claim 3, wherein the search parameters correlate to a location of a peak of a line pattern to search for.

8. The method in accordance with claim 3, wherein the search parameters correlate to a location of a bottom of a line pattern to search for.

9. The method in accordance with claim 3, wherein the search parameters correlate to a relationship between an input line pattern and a line pattern to search for.

10. The method in accordance with claim 9, wherein the relationship is a cross-over between the input line pattern and the pattern to search against.

11. The method in accordance with claim 3, wherein the search parameters correlate to a general shape of a line pattern to search for.

12. The method in accordance with claim 1, further comprising:

an act of displaying the matched set in a manner that a display parameter conveys closeness of the match with the input gesture.

13. The method in accordance with claim 12, wherein the display parameter comprises a position.

14. The method in accordance with claim 12, wherein the display parameter comprises a darkness.

15. The method in accordance with claim 12, wherein the display parameter comprises a size.

16. A computer program product comprising one or more computer-readable storage media having thereon computer-executable instructions that are structured such that, when executed by one or more processors of the computing system, cause the computing system to perform a method for searching a line pattern representation amongst a collection of line pattern representations in response to an input gesture input by a user into the computing system, the method comprising:

an act of automatically matching the input gesture against each of a plurality of line pattern representations, reach representing a line pattern having a changing value in a first dimension as a function of a value in a second dimension; and

an act of visualizing at least one line pattern representation of the matched set on a display of the computing system.

17. The computer program product in accordance with claim 16, wherein the input gesture is an input line pattern, wherein the act of automatically matching the input gesture comprises an act of automatically searching one or more line pattern representations that have line patterns that most closely match the input line pattern.

18. The computer program product in accordance with claim 16, wherein the input gesture has semantic meaning regarding search parameters.

19. The computer program product in accordance with claim 16, the method further comprising:

an act of displaying the matched set in a manner that a display parameter conveys closeness of the match with the input gesture.

20. A system comprising:

a collection of line pattern representations;

an input mechanism that detects user input;

a matching mechanism that matches input gestures input into the input mechanism against each of the collection of line pattern representations to form a matched set, each line pattern representation representing a line pattern having a changing value in a first dimension as a function of a value in a second dimension; and

a visualization component for visualizing at least some of the matched set.
