Abstract

A system and method for correcting mispositioning of an aiming device including extracting features from an information stream which includes position information for an aiming device and comparing the features with feature profiles to determine modifications to remediate mispositioning actions. The information stream with the modifications is provided as a basis for actions of the aiming device.

Claims

1. A method for correcting mispositioning of an aiming device, comprising:

extracting features from an information stream having position information for an aiming device;

comparing the features with feature profiles to determine modifications to remediate mispositioning actions; and

providing a modified information stream including the modifications to remediate mispositioning actions to replace the information stream.

2. The method as recited in claim 1, wherein extracting features from an information stream includes

extracting position information.

3. The method as recited in claim 1, wherein extracting features includes extracting at least one of velocity and acceleration.

4. The method as recited in claim 1, wherein comparing includes identifying slips and jerks in the information stream.

5. The method as recited in claim 1, wherein extracting features includes extracting time-stamped information.

6. The method as recited in claim 5, wherein extracting time-stamped information includes at least one of accelerometer data provided by an accelerometer attached to the aiming device, velocimeter data provided by a velocimeter attached to the aiming device, pressure data provided by a pressure sensor attached to the aiming device, and trigger status for a trigger.

7. The method as recited in claim 1, further comprising a trigger on the aiming device wherein the method further includes:

extracting features and comparing to feature profiles to identify one of unintentional changes to a trigger status, and intended changes to the trigger status that were not generated; and

correcting a time-stamped information stream in which the effect of unintended trigger status changes and missing trigger status changes are eliminated.

8. The method as recited in claim 1, further comprising providing feedback to a user indicating when a correction of an input stream has been performed.

9. The method as recited in claim 1, further comprising generating an alert to a user if a performance threshold is crossed.

10. The method as recited in claim 1, further comprising:

monitoring user actions;

inferring from the user actions whether a previous assessment of an action was accurate; and

adjusting parameters of comparison used and stored feature profiles to improve future performance.

11. The method as recited in claim 1, further comprising permitting a user to decide whether a correction takes place or not.

12. The method as recited in claim 1, further comprising updating the feature profiles by using user actions with the aiming device and a trigger.

13. The method as recited in claim 12, further comprising defining an initial user-specific feature profile in advance of the user starting to use the aiming device and trigger.

14. The method as recited in claim 12, further comprising generating a report summarizing user performance, the feature profiles that have been calculated, and corrections made.

15. The method as recited in claim 14, further comprising sending the report to a third party.

16. A computer program product for correcting mispositioning of an aiming device comprising a computer useable medium including a computer readable program, wherein the computer readable program when executed on a computer causes the computer to perform the steps of:

extracting features from an information stream having position information for an aiming device;

comparing the features with feature profiles to determine modifications to remediate mispositioning actions; and

providing a modified information stream including the modifications to remediate mispositioning actions to replace the information stream.

17. A system for correcting mispositioning of an aiming device, comprising:

an aiming device configured to provide data features to indicate position information for the aiming device; and

a data processing module configured to compare the data features with feature profiles to determine modifications to remediate mispositioning actions of the aiming device.

19. The system as recited in claim 17, wherein the aiming device includes at least one of an accelerometer, a velocimeter, a pressure sensor and a trigger.

20. The system as recited in claim 17, further comprising a trigger on the aiming device wherein trigger status is includes in the feature profiles and is used to identify one of unintentional changes to the trigger status, and intended changes to the trigger status that were not generated such that effects of unintended trigger status changes and missing trigger status changes are corrected.

18. The system as recited in 17, wherein the aiming device includes one of a computer mouse, a track ball, a joystick, a camera, a video camera and a weapons system.
