Abstract

Examples of performing an update of a display device are described. In some implementations, user gesture data may be received in response to a user gesture being performed on a touch sensitive surface of the display device. In response to determining that the user gesture data is unrecognized, performing one or more default actions, including performing an update of the display device. The update may include performing a flash of the display device. The user gesture data may be associated with the one or more actions automatically or in response to the user providing input to associate the user gesture data with the one or more actions. The user gesture and the associated one or more actions may be stored such that the update of the display device may be performed when the user gesture is subsequently performed.

Claims

1. An electronic device comprising:

a touchscreen display;

one or more processors coupled to the touchscreen display; and

computer-readable storage media comprising instructions executable by the one or more processors to perform acts comprising;

presenting a portion of a digital item on the touchscreen display;

receiving user gesture data corresponding to a user gesture performed on the touchscreen display;

comparing the user gesture data to one or more stored gesture data items; and

determining that the user gesture data does not match the one or more stored user gesture data items; and

performing a flash update of the touchscreen display, the flash update comprising;

changing each pixel of the touchscreen display to a first color;

changing each pixel of the touchscreen display from the first color to a second color to normalize a contrast of pixels of the touchscreen display; and

re-displaying the portion of the digital item.

2. The electronic device of claim 1, the acts further comprising:

storing the user gesture data in association with the flash update.

3. The electronic device of claim 1, the acts further comprising:

receiving user input;

storing the user gesture data in association with the flash update based at least in part on the user input.

4. The electronic device of claim 1, wherein:

the user gesture comprises a single gesture made using a continuous motion, the user gesture including;

a first swipe gesture in a first direction; and

a second swipe gesture in a second direction, the second direction being different from the first direction.

5. The electronic device of claim 1, wherein the user gesture is performed using a continuous motion.

6. A computer-implemented method comprising:

presenting a portion of content of an item on a touchscreen display;

receiving user gesture data in response to a user gesture being performed on the touchscreen display;

comparing the user gesture data with previously stored gesture data items;

determining that the user gesture data differs from individual ones of the previously stored gesture data items;

performing a flash update of the touchscreen display to reduce a ghosting of the touchscreen display, the flash update comprising;

changing each pixel of the touchscreen display to a first color;

changing the each pixel of the touchscreen display from the first color to a second color; and

re-displaying the portion of the content of the item;

creating an association of the user gesture data with the flash update; and

storing the user gesture data and the association with the flash update.

7. The computer-implemented method of claim 6, further comprising:

receiving second user gesture data in response to a second user gesture being performed on the touchscreen display;

determining a time interval between receiving the user gesture data and receiving the second user gesture data; and

performing one or more additional flash updates of the touchscreen display based on the time interval, each of the one or more additional flash updates comprising;

changing each pixel of the touchscreen display to a first color; and

changing each pixel of the touchscreen display from the first color to a second color.

8. The computer-implemented method of claim 6, further comprising:

recognizing the user gesture data; and

performing the flash update of the touchscreen display.

9. The computer-implemented method of claim 6, wherein the method further comprises:

receiving input to associate the user gesture with the flash update.

10. The computer-implemented method of claim 6, wherein:

the user gesture comprises a single gesture that is made using a continuous motion and includes at least a first swipe gesture in a first direction and a second swipe gesture in a second direction that is different from the first direction.

11. The computer-implemented method of claim 10, wherein:

the second direction is approximately opposite to the first direction.

12. A computing device comprising:

a display device having a touch sensitive surface and comprising a plurality of pixels;

one or more processors coupled to the display device; and

computer-readable media comprising instructions executable by the one or more processors to perform acts comprising;

displaying a portion of media content on the display device;

receiving user gesture data in response to a user gesture being performed on the touch sensitive surface of the display device;

comparing the user gesture data with one or more stored gesture data items;

determining that the user gesture data differs from the one or more stored gesture data items;

performing a flash update of the display device to reduce a visual effect of ghosting, the flash update comprising;

changing each pixel of the plurality of pixels to a first color;

changing each pixel of the plurality of pixels from the first color to a second color; and

displaying the portion of the media content.

13. The computing device of claim 12, wherein the acts further comprise:

prompting a user to perform the user gesture;

receiving the user gesture data; and

storing the user gesture data in association with one or more actions that include performing the flash update of the display device.

14. The computing device of claim 12, wherein the acts further comprise:

enabling a gesture learning mode;

receiving a selection of at least one action; and

storing the user gesture data in association with the at least one action.

15. The computing device of claim 12, the acts further comprising:

receiving second user gesture data in response to the user gesture being performed on the touch sensitive surface of the display device;

determining a time interval between receiving the user gesture data and the second user gesture data; and

setting a timer to periodically perform the flash update of the display device based on the time interval.

16. The computing device of claim 12, the acts further comprising:

automatically performing one or more default actions in addition to performing the flash update of the display device.

17. The computing device of claim 12, the acts further comprising:

automatically storing an association between the user gesture data and performing the flash update of the display device.

18. The computing device of claim 12, wherein:

the user gesture simulates a gesture to clean a portion of the touch sensitive surface of the display device.

19. The computing device of claim 18, wherein:

the user gesture to clean the portion of the touch sensitive surface of the display device comprises a single gesture that is made using a continuous motion and that includes at least a first swipe gesture in a first direction.

20. The computing device of claim 19, wherein:

the user gesture to clean the portion of the touch sensitive surface of the display device further comprises a second swipe gesture in a second direction, the second direction being approximately opposite to the first direction.
