Video Playback Pausing for Closed Caption Comprehension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In closed captioned videos, the length of the closed captioned text can lead to contextual loss of material comprehension due to slow reading speeds or knowledge density, resulting in incomplete understanding of the content being presented.
Innovation Solution
A method that estimates the time required for a user to read and understand captions, pausing the video playback accordingly to allow for comprehension, utilizing user profiles and collaborative filtering to determine optimal pause times based on reading speed and content complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video playback continues without pausing to allow caption reading, then video playback continuity is maintained, but user comprehension of caption content deteriorates due to slow reading speed and knowledge density
Solution Approach 1:
The system performs preliminary estimation of reading time for closed captions before the user actually reads them. By analyzing caption length, knowledge density, and user reading speed in advance, the system determines the appropriate pause duration beforehand, ensuring the video is paused early enough for the user to comprehend the captions fully.
Solution Approach 2:
The pause duration is not fixed but dynamically adjusted based on real-time analysis of caption characteristics (length, knowledge density) and user-specific reading speed. The system continuously adapts the pause length to match the actual reading requirements, making the playback control flexible and personalized rather than static.
2Reliability
If video playback is paused frequently to allow caption reading, then user comprehension improves, but video playback efficiency deteriorates due to increased interruptions
Solution Approach 1:
The system changes the parameter of pause duration based on multiple factors including caption length, knowledge density, and user reading speed. Rather than using a fixed pause time, the system calculates and applies variable pause durations that are optimized for each specific caption segment, thereby improving comprehension while minimizing unnecessary interruptions to playback efficiency.
3Reliability
If pause duration is extended to ensure complete caption comprehension, then reading comprehension improves, but total viewing time increases
Solution Approach 1:
The system incorporates user feedback mechanisms where users can indicate whether they understood the captions during or after the pause. This feedback is used to adjust and refine future pause durations, ensuring that the pause length is optimized for actual comprehension needs rather than being overly conservative, thereby reducing unnecessary extension of total viewing time.

AI summary
A method, computer system, and a computer program product for playing a video recording that includes captions, wherein each caption includes a textual transcription of an audio portion of the video, a description of non-speech elements of the video, or both, is provided. The present invention may include rendering a video, identifying a first portion of the video that includes a first caption, and, in response to identifying the first portion of the video, estimating a second time period for a particular user to read and understand text in the first caption. The present invention may further include determining whether the second time period for the particular user to read and understand text in the first caption is greater than the first time period for rendering the first portion of the video. The present invention may lastly include pausing the video for a third time period.
