Adaptive Content Replay for Low-Proficiency Subtitle Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assisting language learning through closed captions and subtitles do not account for a user's proficiency level, leading to difficulties in reading and understanding content, especially for those with low proficiency, resulting in stagnation or loss of interest.
Innovation Solution
A system that adjusts the playback of content items based on user language proficiency by generating portions at a level below the user's proficiency, altering language, adjusting playback speed, and rewriting timed text files to facilitate learning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If closed timed texts and subtitles are used to provide text version of speech, then accessibility and language learning are improved, but the text cannot be read within the display time for users with low proficiency levels
Solution Approach 1:
The system dynamically adjusts playback speed based on user proficiency level and reading pace. For users with low proficiency, the playback speed is slowed down to match their reading speed, allowing them to read the timed text within the display time without falling behind the content progression.
Solution Approach 2:
The system changes the timing parameters of the timed text display to match the user's reading pace. By adjusting the duration that text remains on screen and synchronizing it with modified playback speed, users have sufficient time to read and comprehend the text without losing synchronization with the audio-visual content.
2Loss of information
If users rewind and replay scenes to re-read timed text, then understanding is improved, but viewing time and efficiency are reduced
Solution Approach 1:
The system performs preliminary adjustment of playback speed and timed text timing before the user begins viewing. By pre-configuring the playback parameters to match the user's proficiency level and reading pace, the content is made readable at normal playback speed, eliminating the need for users to rewind and replay scenes to comprehend the timed text.
3Adaptability or versatility
If content is provided at user's current proficiency level, then learning challenge is maintained, but users with low proficiency cannot understand or progress
Solution Approach 1:
The system changes the playback speed parameter to match the user's proficiency level. For users with low proficiency, the content is played back at a slower speed, making it comprehensible while still maintaining engagement. This allows users to consume content at their current level without requiring the content itself to be simplified.

AI summary
Systems and methods for replaying a portion of a content item based on the user's language proficiency level in a secondary language is disclosed. The system accesses a user profile comprising a user's proficiency level in at least one secondary language, the secondary language being their non-native language. A command to replay a first portion of a content item is received and, in response to receiving the replay command, the system generates for display the first portion of the content item at a level below the user's proficiency level in the secondary language.
