Abstract

A method and a system for estimating the intended position of at least one target-inaccurate user inputs applied by a user to an input device are provided herein. The method may include the following steps: analyzing one or more points of contact applied to a an input device, to derive input parameters associated with the user inputs; applying a decision function to the derived input parameters, to estimate an intended position of the at least one target-inaccurate input of the user, wherein the decision function is tailored for the user and is further based on user parameters associated with the user; and overriding, at a level of the input device, the actual user inputs with the estimated intended position of the at least one target-inaccurate input of the user.

Claims

1. A system for estimating an intended position of at least one target-inaccurate input of a user over a gestural or haptic input device, the system comprising:

a gestural or haptic input mechanism;

a computer processor;

an analysis module executed by said computer processor configured to analyze one or more actual points of interaction associated with said target-inaccurate input, over said input device, to derive parameters;

an estimator module executed by said computer processor configured to apply a decision function to said derived parameters, to estimate the intended input from among the at least one target-inaccurate sets of input of said user, wherein the decision function may be tailored for said user and may be further based on parameters associated with said user.

2. The system according to claim 1, wherein the computer processor is configured to override, at the touch-sensitive input device level, the actual points of input with the estimated intended position of at least one target-inaccurate input set of said user.

3. The system according to claim 1, wherein the parameters comprise time stamped metrics of at least one of:

X-Y position, size, duration, intensity and orientation.

4. The system according to claim 1, wherein the computer processor is further configured to obtain the parameters associated with the user via a calibration session that comprises monitoring predefined input events carried by the user over the input device.

5. The system according to claim 1, wherein the computer processor is further configured to obtain the parameters associated with the user by monitoring usage patterns of said user.

6. The system according to claim 1, wherein the input device is a touch screen.

7. The system according to claim 1, wherein the input device is an eye-movement detector.

8. The system according to claim 7, wherein the decision function takes into account a virtual object presented on the touch screen proximal to the X-Y location of the actual points of contact.

9. A method of estimating an intentional position of at least one target-inaccurate set of inputs of a user over an input device, the method comprising:

analyzing one or more sets of input applied to an input device, to derive parameters associated with said points of contact;

applying a decision function to said derived parameters, to estimate an intended position of the at least one target-inaccurate sets of input of said user, wherein the decision function is tailored for said user and is further based on user parameters associated with said user; and

overriding, at a level of the input device, the actual sets of user input with the estimated intended position of the at least one target-inaccurate sets of input of said user.

10. The method according to claim 9, wherein the touch parameters comprise time stamped metrics of at least one of:

X-Y position, size, duration, intensity and orientation.

11. The method according to claim 9, wherein the user parameters comprise at least one of:

X-Y drift, multiplicity of touch;

intensity, duration, and tremor magnitude.

12. The method according to claim 9, further comprising obtaining the user parameters via a calibration session that comprises monitoring predefined touch events carried by the user over the touch-sensitive input device.

13. The method according to claim 9, wherein the touch-sensitive input device is a touch screen.

14. The method according to claim 13, wherein the decision function takes into account objects presented on the touch screen proximal to the X-Y location of the actual finger touches.

15. A non-transitory computer readable medium for estimating an intended position of at least target-inaccurate touch of a user over a touch-sensitive input device comprising a set of instructions that when executed cause at least one processor to:

analyze one or more points of contact applied to a touch-sensitive input device, to derive touch parameters associated with said points of contact;

apply a decision function to said derived touch parameters, to estimate an intended position of the at least one target-inaccurate touch of said user, wherein the decision function is tailored for said user and is further based on user parameters associated with said user; and

override, at a level of the touch-sensitive input device, the actual points of user contact with the estimated intended position of the at least one target-inaccurate touch of said user.

16. The non-transitory computer readable medium according to claim 15, wherein the touch parameters comprise time stamped metrics of at least one of:

X-Y position, size, duration, intensity and orientation.

17. The non-transitory computer readable medium according to claim 15, wherein the user parameters comprise at least one of:

X-Y drift, multiplicity of touch;

intensity, duration, and tremor magnitude.

18. The non-transitory computer readable medium according to claim 15, further comprising obtaining the user parameters via a calibration session that comprises monitoring predefined touch events carried by the user over the touch-sensitive input device.

19. The non-transitory computer readable medium according to claim 15, wherein the touch-sensitive input device is a touch screen.

20. The non-transitory computer readable medium according to claim 19, wherein the decision function takes into account objects presented on the touch screen proximal to the X-Y location of the actual finger touches.
