Abstract

A server receives a sound file corresponding to a sound corresponding to a media file. The server compares the sound file to a library of media file sound recordings to identify a media file and a matching position in the media file of a final sound in the sound file. The server determines, from a data structure of media abbreviations, a media abbreviation that corresponds to a final sound data present in the sound file. The server transmits the media abbreviation to the addressable device.

Claims

1. A method for playing back media previously played to a user, the method comprising:

a computer obtaining a media file having a tag corresponding to a grade level among a plurality of grade levels, wherein the grade level indicates a complexity of a media file content with respect to concepts described by the media file;

the computer rendering the media file to a user;

the computer detecting a user distraction, the user distraction comprising a level of inattentiveness based on a threshold ratio of eyes-closed to eyes-open, as measured from camera-originated streaming video of a user'"'"'s eye, wherein the threshold ratio is a duration of eyes closed over a predetermined sampling period such that the threshold is more than 0% and less than 100%;

the computer detecting user absence, as measured by the user'"'"'s eye persistently being not engaged to the rendered media, the user absence corresponding to a quiescent period between user distraction and a user absence;

the computer receiving a playback request, and in response, rewinding the media from a point at an end of the quiescent period to a point that corresponds to a rewind amount calculated from a table that correlates the grade level among the plurality of grade levels to rewind amounts and modified by increasing the rewind amount in proportion to the level of inattentiveness.

2. The method of claim 1, further comprising:

the computer obtaining user-characterized rewind description; and

the computer storing user-characterized rewind description as the table.

3. The method of claim 1, wherein rewinding further comprises:

the computer increasing the rewind based on the level of inattentiveness, and the level of inattentiveness being based, in part, on inputs from a microphone.

4. The method of claim 1, wherein the user absence is detected based on receiving a user input to stop rendering.

5. The method of claim 4, wherein a duration of absence modifies the rewind amount to be greater as a function of increasing the duration.

6. The method of claim 4, wherein the rewinding is an interval of time, in the case of a media file being audio or video.

7. A computer program product for playing back media previously played to a user, the computer program product comprising:

a computer readable non-transitory storage having computer program code embodied therewith, the computer program product comprising;

computer program code configured to obtain a media file having a tag corresponding to a grade level among a plurality of grade levels, wherein the grade level indicates a complexity of a media file content with respect to concepts described by the media file;

computer program code configured to render the media file to a user;

computer program code configured to detect a user distraction, the user distraction comprising a level of inattentiveness based on a threshold ratio of eyes-closed to eyes-open, as measured from camera-originated streaming video of a user'"'"'s eye, wherein the threshold ratio is a duration of eyes closed over a predetermined sampling period such that the threshold more than 0% and less than 100%;

computer program code configured to detect user absence, as measured by the user'"'"'s eye persistently being not engaged to the rendered media, the user absence corresponding to a quiescent period between user distraction and a user absence; and

computer program code configured to receive a playback request, and in response, rewind the media from a point at an end of the quiescent period to a point that corresponds to a rewind amount calculated from a table that correlates the grade level among the plurality of grade levels to rewind amounts and modified by increasing the rewind amount in proportion to the level of inattentiveness.

8. The computer program product of claim 7, further comprising:

computer program code to obtain user-characterized rewind description; and

store user-characterized rewind description as the table.

9. The computer program product of claim 7, wherein the computer program code to rewind further comprises computer program code to increase the rewind based on the level of inattentiveness, and the level of inattentiveness being based, in part, on inputs from a microphone.

10. The computer program product of claim 7, wherein the user absence is detected based on receiving a user input to stop rendering.

11. The computer program product of claim 10, wherein a duration of absence modifies the rewind amount to be greater as a function of increasing the duration.

12. The computer program product of claim 10, wherein the rewinding is with respect to an interval of time, in the case of a media file being audio or video.
