Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for combining authentication and application shortcut. An example method includes detecting, by a device having a touchscreen, a gesture by a user on the touchscreen while the device is in a sleep mode; classifying the gesture, by the device, as an intentional gesture or an accidental gesture; maintaining the device in the sleep mode if the gesture is classified as an accidental gesture; responsive to determining, by the device, that the gesture matches one or more confirmed gestures stored on the device based at least in part on a set of predefined criteria, if the gesture is classified as an intentional gesture: recognizing the user as authenticated; and without requiring additional user input, selecting an application, from a plurality of different applications, according to the gesture and launching the application on the device.

First claim

What is claimed is:

1. A method comprising:
detecting, by a device having a touchscreen, a first gesture by a user on the touchscreen while the device is in a sleep mode;
classifying the first gesture, by the device, as an intentional gesture or an accidental gesture and either (i) maintaining the device in the sleep mode if the first gesture is classified as an accidental gesture, or (ii) determining, by the device, whether the first gesture matches one or more confirmed gestures stored on the device if the first gesture is classified as an intentional gesture; and,
if the first gesture is classified as an intentional gesture, either (i) requiring an additional user input to authenticate the user if the first gesture does not match one or more confirmed gestures stored on the device, or (ii) recognizing the user as authenticated and selecting and launching an application from a plurality of applications on the device according to the first gesture, if the first gesture matches one or more confirmed gestures stored on the device, without requiring any user input in addition to the first gesture to authenticate the user or select and launch the application.

2. The method of claim 1 , further comprising:
identifying the gesture as a drawing of an alphanumeric character on the touchscreen, the alphanumeric character having an alphanumeric value; and
providing the alphanumeric value as an input to the application.

3. The method of claim 1 , further comprising:
in accordance with a determination that the gesture is classified as an intentional gesture and the gesture fails to match one or more confirmed gestures stored on the device:
presenting, to the user, a password-based authentication mechanism; and
requiring the user to input a password.

4. A computing device comprising:
one or more processors;
a touchscreen; and,
one or more storage units storing instructions that when executed by the one or more processors cause the computing device to perform operations comprising:
detecting, by a device having a touchscreen, a first gesture by a user on the touchscreen while the device is in a sleep mode;
classifying the first gesture, by the device, as an intentional gesture or an accidental gesture and either (i) maintaining the device in the sleep mode if the first gesture is classified as an accidental gesture, or (ii) determining, by the device, whether the first gesture matches one or more confirmed gestures stored on the device if the first gesture is classified as an intentional gesture; and,
if the first gesture is classified as an intentional gesture, either (i) requiring an additional user input to authenticate the user if the first gesture does not match one or more confirmed gestures stored on the device, or (ii) recognizing the user as authenticated and selecting and launching an application from a plurality of applications on the device according to the first gesture, if the first gesture matches one or more confirmed gestures stored on the device, without requiring any user input in addition to the first gesture to authenticate the user or select and launch the application.

5. The device of claim 4 , wherein the operations further comprise identifying the first gesture as a drawing of an alphanumeric character on the touchscreen, the alphanumeric character having an alphanumeric value.

6. The device of claim 5 , wherein the operations further comprise:
providing the alphanumeric value as an input to the application.

7. The device of claim 4 , wherein the operations further comprise:
in accordance with a determination that the gesture is classified as an intentional gesture and the gesture fails to match one or more confirmed gestures stored on the device:
presenting, to the user, a password-based authentication mechanism; and
requiring the user to input a password.

8. The device of claim 4 , wherein the operations further comprise:
collecting an intentional gesture from a user who has been authenticated; and
identifying the intentional gesture as a confirmed gesture.

9. The device of claim 4 , wherein the operations further comprise:
while detecting the gesture on the touchscreen while the device is in a sleep mode, displaying a visual aid tracing the gesture on the touchscreen at a reduced power consumption level.

10. A non-transitory computer storage medium encoded with a computer program, the computer program comprising instructions that when executed by a computing device having a touchscreen cause the computing device to perform operations comprising:
detecting, by a device having a touchscreen, a first gesture by a user on the touchscreen while the device is in a sleep mode;
classifying the first gesture, by the device, as an intentional gesture or an accidental gesture and either (i) maintaining the device in the sleep mode if the first gesture is classified as an accidental gesture, or (ii) determining, by the device, whether the first gesture matches one or more confirmed gestures stored on the device if the first gesture is classified as an intentional gesture; and,
if the first gesture is classified as an intentional gesture, either (i) requiring an additional user input to authenticate the user if the first gesture does not match one or more confirmed gestures stored on the device, or (ii) recognizing the user as authenticated and selecting and launching an application from a plurality of applications on the device according to the first gesture, if the first gesture matches one or more confirmed gestures stored on the device, without requiring any user input in addition to the first gesture to authenticate the user or select and launch the application.

11. The non-transitory computer storage medium of claim 10 , wherein the operations further comprise:
identifying the first gesture as a drawing of an alphanumeric character on the touchscreen, the alphanumeric character having an alphanumeric value.

12. The non-transitory computer storage medium of claim 11 , wherein the operations further comprise:
providing the alphanumeric value as an input to the application.

13. The non-transitory computer storage medium of claim 10 , wherein the operations further comprise:
in accordance with a classification of the first gesture as an intentional gesture and a determination that the first gesture matches one or more confirmed gestures stored on the device:
determining, by the device, that the device is in a locked mode; and,
without requiring any additional user input, unlocking the device.

14. The non-transitory computer storage medium of claim 10 , wherein the operations further comprise:
identifying the first gesture as a drawing of a predefined shape on the touchscreen.

15. The non-transitory computer storage medium of claim 10 , wherein the operations further comprise:
in accordance with a classification of the first gesture as an intentional gesture and a determination that the first gesture does not match one or more confirmed gestures stored on the device:
presenting, to the user, a password-based authentication mechanism; and,
requiring the user to input a password.

16. The non-transitory computer storage medium of claim 15 , wherein the operations further comprise:
determining, by the device, that the first gesture identifies an alphanumeric value or a predefined shape; and,
automatically providing the alphanumeric value or the predefined shape identified by the first gesture as a first portion of an input to the password-based authentication mechanism.
