Abstract

Automatic annotation of recorded lectures includes the annotation of recorded presentations as presented on a computer screen during a presentation. Such annotation is accomplished with metadata that indicates the original slide and the time in the presentation that the slide was presented. Registration of the presentation tags the presentation with this metadata, which uniquely identifies the presentation and each slide. The metadata enables future searching of the recorded presentation for the annotation, such that segments of recorded presentations in which the slide was presented can be recalled. The searching function can also be used in an integrated system with other applications to enable recall of segments of relevant recorded presentations.

Claims

1. A computer readable medium containing computer readable instructions which, when executed by a processor, implement a method comprising the steps of:

providing access to a presentation comprising a plurality of slides;

uniquely identifying each of said plurality of slides in said presentation with metadata containing a unique identification (UID);

upon receiving a request for at least one slide by a user from said presentation, providing said slide to said user; and

upon accessing said slide, registering said UID of said slide to track each use of a slide within said presentation and to track a sequence in which said slides in said presentation are accessed.

2. The computer readable medium of claim 1, wherein said computer readable medium contains content that is associated with a textbook.

3. The computer readable medium of claim 1, wherein said computer readable medium comprises any of a computer memory, computer disk, remote memory, networked attached storage (NAS), compact disk (CD), digital video disk (DVD), disk-on-key, read only memory (ROM), and non-volatile memory (NVM).

4. A computer implemented method, comprising the steps of:

presenting one or more slides from a presentation comprising a plurality of slides, said presentation of slides occurring in a sequence determined by a lecturer, each slide having a unique identification (UID);

recording a timestamp with each slide presented to identify a time at which said slide was presented; and

storing in memory the sequence of UIDs and the timestamp for each of the slides presented.

5. The method of claim 4, further comprising the steps of:

determining a sequence of presentation of slides of the presentation prior to presenting the slides; and

storing the sequence of presentation of slides in a memory.

6. The method of claim 4, further comprising the step of:

providing a lecturer with a log on facility to allow said lecturer to access and display said presentation.

7. The method of claim 4, further comprising the step of:

selecting a presentation from a plurality of presentations.

8. The method of claim 4, wherein said computer readable medium contains content that is associated with a textbook.

9. The method of claim 4, wherein said computer readable medium comprises any of a computer memory, computer disk, remote memory, networked attached storage (NAS), compact disk (CD), digital video disk (DVD), disk-on-key, read only memory (ROM), and non-volatile memory (NVM).

10. The method of claim 4, further comprising the step of:

associating said presentation with any of an audio track and a video track.

11. A computer implemented method, comprising the steps of:

retrieving a presentation list comprising at least one slide from a plurality of slides in said presentation, each slide comprising a unique identification (UID) and a respective timestamp representing a time at which said slide was presented; and

presenting slides from said presentation in a sequence determined from the presentation list.

12. The method of claim 11, further comprising the steps of:

displaying one or more feedback options;

receiving a user selected feedback option; and

storing the user selected feedback option in a memory.

13. The method of claim 12, further comprising the step of:

associating a timestamp with the user selected feedback, the timestamp being respective of the time from a start of the presentation.

14. The method of claim 13, wherein the one or more feedback options are displayed on any of an overlay to a presented slide and a mobile device display.

15. The method of claim 11, further comprising the step of:

providing a user with a log on facility to allow said user to access and display said presentation.

16. The method of claim 11, further comprising the step of:

selecting the presentation from a plurality of presentations.

17. The method of claim 11, further comprising the step of:

providing any of an audio track associated with the presentation and a video track associated with the presentation.

18. The method of claim 11, wherein the presentation list corresponds to a question, the answer of which corresponds to one or more of the slides in the presentation list.

19. A computer implemented method, comprising the steps of:

identifying a user'"'"'s input device in connection with a plurality of presentations;

selecting a presentation from said plurality of presentations;

receiving feedback regarding said presentation from a user via the user'"'"'s input device;

tagging said presentation with the user feedback; and

retrieving the user feedback.

20. The method of claim 19, further comprising the step of:

displaying the feedback options on a user'"'"'s mobile device.

21. The method of claim 19, further comprising the step of:

associating the presentation with any of a unique identification (UID) of a slide of the presentation;

a timestamp, wherein timestamp is respective of a time from a start of the presentation;

a presentation identification; and

a user identification.

22. The method of claim 19, wherein the feedback is provided in real-time while the presentation is displayed.
