Abstract

Techniques are provided for creating annotations of user input. In one technique, user input is received on a screen while a video is being played. The user input corresponds to a period of time that includes a first time and a second time. While the user input is received, a first snapshot is generated of the user input and a second snapshot is generated for the user input. The first snapshot corresponds to the first time and the second snapshot corresponds to the second time. A first annotation that identifies the first time is created based on the first snapshot. A second annotation that identifies the second time is created based on the second snapshot. Each snapshot is stored in association with the video.

Claims

1. A method comprising:

while a video is being played by a video player application on a portion of a screen of a computing device;

receiving user input on the portion of the screen, wherein the user input corresponds to, in the video, a period of time that includes a first time and a second time that is after the first time;

while receiving the user input;

generating a first snapshot, of the user input, that corresponds to the first time;

creating, based on the first snapshot, a first annotation that identifies the first time;

storing the first annotation in association with the video;

generating a second snapshot, of the user input, that corresponds to the second time;

creating, based on the second snapshot, a second annotation that identifies the second time;

storing the second annotation in association with the video.

2. The method of claim 1, further comprising:

sending, over a network, from the computing device, the first annotation and video identification data that identifies the video.

3. The method of claim 1, further comprising, after storing the first annotation in association with the video:

while a second video player application is playing the video;

determining a current time that is relative to the beginning of the video;

performing a comparison between the current time and the first time;

based on the comparison, causing the first annotation to be displayed on a screen of a second computing device.

4. The method of claim 3, wherein the computing device is a first computing device that is different than the second computing device.

5. The method of claim 3, further comprising:

generating time data that identifies a plurality of times that includes the first time and a third time that is after the first time;

wherein causing the first annotation to be displayed comprises causing the first annotation to be displayed for a time range indicated by the first time and the third time.

6. The method of claim 1, further comprising:

receiving, over a network, a third annotation that is different than the first annotation and the second annotation and that is associated with a third time and a second video;

while the second video is being played by the video player application;

determining a current time that is relative to the beginning of the second video;

performing a comparison between the current time and the third time;

based on the comparison, causing the third annotation to be displayed on the screen of the computing device.

7. The method of claim 1, further comprising, in response to receiving the user input:

identifying a particular section among a plurality of pre-defined sections in the video, wherein frames from the particular section are displayed when the user input is received;

storing, in association with the first annotation, section data that identifies the particular section.

8. The method of claim 7, further comprising, after storing the first annotation in association with the video:

while the video player application is playing the video and displaying the first annotation;

determining whether video data from the particular section is being displayed;

in response to determining that video data from the particular section is no longer being displayed, removing the first annotation from the screen of the computing device.

9. The method of claim 7, wherein:

each section of the plurality of pre-defined sections corresponds to a slide in a slideshow presentation in the video data;

at least two sections in the plurality of pre-defined sections have different time durations during normal playback of the video.

10. A system comprising:

one or more processors;

one or more computer-readable media storing instructions which, when executed by the one or more processors, cause;

while a video is being played by a video player application on a portion of a screen of a computing device;

receiving user input on the portion of the screen, wherein the user input corresponds to, in the video, a period of time that includes a first time and a second time that is after the first time;

while receiving the user input;

generating a first snapshot, of the user input, that corresponds to the first time;

creating, based on the first snapshot, a first annotation that identifies the first time;

storing the first annotation in association with the video;

generating a second snapshot, of the user input, that corresponds to the second time;

creating, based on the second snapshot, a second annotation that identifies the second time;

storing the second annotation in association with the video.

11. The system of claim 10, wherein the instructions, when executed by the one or more processors, further cause:

sending, over a network, from the computing device, the first annotation and video identification data that identifies the video.

12. The system of claim 10, wherein the instructions, when executed by the one or more processors, further cause, after storing the first annotation in association with the video:

while a second video player application is playing the video;

determining a current time that is relative to the beginning of the video;

performing a comparison between the current time and the first time;

based on the comparison, causing the first annotation to be displayed on a screen of a second computing device.

13. The system of claim 12, wherein the computing device is a first computing device that is different than the second computing device.

14. The system of claim 12, wherein the instructions, when executed by the one or more processors, further cause:

generating time data that identifies a plurality of times that includes the first time and a third time that is after the first time;

wherein causing the first annotation to be displayed comprises causing the first annotation to be displayed for a time range indicated by the first time and the third time.

15. The method of claim 10, wherein the instructions, when executed by the one or more processors, further cause:

receiving, over a network, a third annotation that is different than the first annotation and the second annotation and that is associated with a third time and a second video;

while the second video is being played by the video player application;

determining a current time that is relative to the beginning of the second video;

performing a comparison between the current time and the third time;

based on the comparison, causing the third annotation to be displayed on the screen of the computing device.

16. The system of claim 10, wherein the instructions, when executed by the one or more processors, further cause, in response to receiving the user input:

identifying a particular section among a plurality of pre-defined sections in the video, wherein frames from the particular section are displayed when the user input is received;

storing, in association with the first annotation, section data that identifies the particular section.

17. The system of claim 16, wherein the instructions, when executed by the one or more processors, further cause, after storing the first annotation in association with the video:

while the video player application is playing the video and displaying the first annotation;

determining whether video data from the particular section is being displayed;

in response to determining that video data from the particular section is no longer being displayed, removing the first annotation from the screen of the computing device.

18. The system of claim 16, wherein:

each section of the plurality of pre-defined sections corresponds to a slide in a slideshow presentation in the video data;

at least two sections in the plurality of pre-defined sections have different time durations during normal playback of the video.
