Real-time analysis of participant understanding

A system comprising:

• a memory comprising non-transitory computer readable instructions;
• and
• a processing device for executing the non-transitory computer readable instructions for performing a method for real-time analysis of participant understanding of at least one participant during a presentation, the method comprising:
• capturing, by a first imaging device, a plurality of images of the at least one participant during the presentation;
• analyzing, by the processing device, the plurality of images to determine a level of understanding of the at least one participant;
• determining, by the processing device, a period of misunderstanding of the at least one participant by comparing the level of understanding of the at least one participant to an understanding threshold, the period of misunderstanding being a period of time during which the level of understanding of the at least one participant is below the understanding threshold;
• based at least in part on determining that the level of understanding of the at least one participant is below the understanding threshold, analyzing, by the processing device, the presentation to associate the period of misunderstanding with a portion of the presentation wherein the analyzing comprises performing tokenization and part-of-speech tagging of text from the portion of the presentation associated with the period of misunderstanding;
• re-presenting to the at least one participant the portion of the presentation associated with the period of misunderstanding;
• and
• capturing, by a second imaging device, video of the presentation and a presenter.

A computer program product comprising:

• a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processing device to cause the processing device to perform a method for real-time analysis of participant understanding of at least one participant during a presentation, the method comprising:
• capturing, by a first imaging device, a plurality of images of the at least one participant during the presentation;
• analyzing, by the processing device, the plurality of images to determine a level of understanding of the at least one participant;
• determining, by the processing device, a period of misunderstanding of the at least one participant by comparing the level of understanding of the at least one participant to an understanding threshold, the period of misunderstanding being a period of time during which the level of understanding of the at least one participant is below the understanding threshold;
• based at least in part on determining that the level of understanding of the at least one participant is below the understanding threshold, analyzing, by the processing device, the presentation to associate the period of misunderstanding with a portion of the presentation wherein the analyzing comprises performing tokenization and part-of-speech tagging of text from the portion of the presentation associated with the period of misunderstanding;
• re-presenting to the at least one participant the portion of the presentation associated with the period of misunderstanding;
• and
• capturing, by a second imaging device, video of the presentation and a presenter.
