Gesture controlled login

1. A method, comprising:

activating, at an information handling device, an optical sensor for a gesture based login;

initiating, using a processor, an identification sequence based on a security level for the gesture based login;

receiving, at the optical sensor, a sequence of user gesture input;

determining if the sequence of user gesture input matches a predetermined sequence of user gesture input stored as training data for the security level,

the determining comprising comparing, using the processor, data points derived from a three dimensional limb acceleration of the user gesture input with the stored training data;

responsive to a successful comparison between the user gesture input and the stored training data, providing an identification result; and

responsive to an unsuccessful comparison between the user gesture input and the stored training data, providing a clue to the user, on the security level, for providing user gesture input for the gesture based login.

2. The method of claim 1 , wherein the receiving comprises receiving a sequence of user gesture input that begins with a user gesture contacting the information handling device.

3. The method of claim 2 , wherein the user gesture contacting the information handling device comprises a user gesture touching a touch screen of the information handling device.

4. The method of claim 1 , wherein the comparing comprises comparing both of gesture movement characteristics of the sequence of user gesture input and object characteristics of the sequence of user gesture input to the predetermined sequence of user gesture input.

5. The method of claim 4 , wherein the gesture movement characteristics comprise timing of different gestures performed within the sequence and conformance of the different gestures to an expected three dimensional pattern of the gestures.

6. The method of claim 4 , wherein the object characteristics comprise size and shape of an object performing a gesture.

7. The method of claim 1 , further comprising providing an indication of a sequence of user gesture input is required for identification used as a login.

8. The method of claim 7 , wherein the indication is provided during collection of the training data.

9. The method of claim 1 , further comprising granting login access to the information handling device based on a match between the sequence of user gesture input and the predetermined sequence of user gesture input stored as training data.

10. The method of claim 1 , wherein to provide a clue further comprises providing a visual indication of an additional sequence of user gesture input.

11. An information handling device, comprising:

an optical sensor;

a processor; and

a memory storing instructions that are executed by the processor to:

activate, at an information handling device, an optical sensor for a gesture based login;

initiate, using a processor, an identification sequence based on a security level for the gesture based login;

receive, at the optical sensor, a sequence of user gesture input;

determine if the sequence of user gesture input matches a predetermined sequence of user gesture input stored as training data for the security level;

the determining comprising comparing, using the processor, data points derived from a three dimensional limb acceleration of the user gesture input with the stored training data;

responsive to a successful comparison between the user gesture input and the stored training data, provide an identification result; and

responsive to an unsuccessful comparison between the user gesture input and the stored training data, provide a clue to the user, based on the security level, for providing user gesture input for the gesture based login.

12. The information handling device of claim 11 , wherein to receive comprises receiving a sequence of user gesture input that begins with a user gesture contacting the information handling device.

13. The information handling device of claim 12 , wherein the user gesture contacting the information handling device comprises a user gesture touching a touch screen of the information handling device.

14. The information handling device of claim 11 , wherein to compare comprises comparing both of gesture movement characteristics of the sequence of user gesture input and object characteristics of the sequence of user gesture input to the predetermined sequence of user gesture input.

15. The information handling device of claim 14 , wherein the gesture movement characteristics comprise timing of different gestures performed within the sequence and conformance of the different gestures to an expected three dimensional pattern of the gestures.

16. The information handling device of claim 14 , wherein the object characteristics comprise size and shape of an object performing a gesture.

17. The information handling device of claim 11 , wherein the instructions are further executable by the processor to provide an indication of a sequence of user gesture input is required for identification used as a login.

18. The information handling device of claim 11 , wherein the instructions are further executable by the processor to grant login access to the information handling device based on a match between the sequence of user gesture input and the predetermined sequence of user gesture input stored as training data.

19. A product, comprising:

a device readable storage device having device readable code stored therewith, the device readable code being executable by a processor and comprising:

code that activates, at an information handling device, an optical sensor for a gesture based login;

code that initiates, using a processor, an identification sequence based on a security level for the gesture based login;

code that receives, via the optical sensor, a sequence of user gesture input;

code that determines if the sequence of user gesture input matches a predetermined sequence of user gesture input stored as training data for the security level;

wherein to determine comprises comparing, using the processor, data points derived from a three dimensional limb acceleration of the user gesture input with the stored training data;

code that, responsive to a successful comparison between the user gesture input and the stored training data, provides an identification result; and

code that, responsive to an unsuccessful comparison between the user gesture input and the stored training data, provides a clue to the user, based on the security level, for providing user gesture input for the gesture based login.
